Phd2 dither settings A setting of 10 pixels in NINA tells PHD2 to move the GUIDE camera 10 pixels. 00 default is 1. At which point, it was taking too much time, and I called it quites on dithering so not to lose more imaging time. Sometimes they stop after the PHD2 get a command to dither from Nina. 5, 1, 2, 3, and 5 pixels in PHD2, multiplied by the dither scale setting. Branches Tags Any ideas what could be causing this? I have all of the setting on my computer set to max performance and NOT to shut anything off to save power. 45 pixels on my imaging camera which seems to be enough (considering that the random dither can be Page 1 of 2 - APT, Dither, PHD2 and me - posted in Beginning Deep Sky Imaging: Hi, I am about to loose my mind. December 7, 2019 - macOS Catalina. 5 2 1. A- but no issues with Asiair - posted in Beginning Deep Sky Imaging: Ive been trying to figure out what causes, that when I dither, my mount have a hard time returning to normal guiding with PHD2. FYI, my APT scale is 3 and my PHD scale is 8 and my dithers are set to a random pattern but they regularly dither by 10/15 pixels. Im using an EQM-35 Pro with the main imaging train being an Evostar 72ED (72/420) and a Sony A5100. To dither you’ll need to have a connection between your telescope mount and the computer or laptop so that the astrophotography dithering software can move your mount between each exposure. 5x, a dithering distance setting of 3 in APT (leaving the scale set at 1. Gear: TS-Optics PHOTOLINE 80mm f/6 : Aperture 80 mm Focal length 480 mm / focal Ratio f/6 Sky-Watcher 9x50 Finderscope :focal length 181 mm ,I think QHY5 Monochrome for guiding: Sensor Mitron . 5 (perhaps not). My APT settings are: Guiding Program:PHD2 Guiding Auto Dithering: on Dithering Distance:1 Stability: . After a meridian flip (auto or manual) is it necessary to recalibrate PHD2? Dithering settings, please help. 6 pixels on the imaging chip (1. Im confused as to what the settings should be and was wondering if someone can help me out here. Attached is a screen shot of my scenario. The enclosed image was enhanced to show the problem. Each algorithm has a set of parameters that control how observed changes in guide star position (star deflections) are translated into guiding corrections that will be sent to the mount. Search . Try running the guide assistant to check the amount of dec backlash. Help! - posted in Beginning Deep Sky Imaging: Hi folkses I hope this is the right forum for this question, apologies if its not. Pixels - This refers to how many pixels the auto-guider will move its guide star. thank you for your explanation, i did missunderstand this ! Back to top Dithering settings are not on the same guide screen as aggressiveness, they are over on the guide cam setting page of ASIAIR. I tried this with various options changed and various pixel amount to dither and from an unsettled dither in SGP. That will work out to be a dither of up to 30 arc seconds given Page 1 of 3 - ZWO AM5 and PHD2 - guiding puzzles - posted in Mounts: There have been a lot of posts (including from me) on guiding for AM5 in the two other main threads, but were getting losts so i thought Id start a more focused thread. 5 and 10 seconds and it constantly fails to settle. PHD2 will try to move the star by 25 pixels during calibration; so the 2 Meridian Flip and PHD2 Calibration - posted in Beginning Deep Sky Imaging: Ive seen different thoughts on this subject, and I couldnt find it in a CN search, so Ill ask it again. Alternately, I can just not dither at all and use CC in Pixinsight. Which would be the result of whatever values I have in APT combined with the PHD2 dithering scale? Dither with PHD2 7 PHD2, Star Adventurer ii and dithering - posted in Beginning Deep Sky Imaging: I have been using my SAii over the past year with a modified Canon 800D and achieved some pleasing results. Would rather continue using PHD2, which I am familiar with, than learn TSX guiding. scale=5 x pixel=3 = a move of 15 pixels . It also communicates with NINA to stop PHD2 when slewing, stop during Auto-Focus, start when imaging. 92 arc-sec/px, Binning = 1, Focal length = 840 mm If you have an older version, you could use the phd2 dither app to effect the same. Contribute to OpenPHDGuiding/phd2 development by creating an account on GitHub. 2 really works like a video camera – it always takes images continuously on whatever camera you have selected. (so to speak) So i guess i should use in APT dither distance 3 , that x3 x 1,98 is say roughly 18 pixels to really stay on the safe side. This is only a warning, the session is continuing. 8 dither is set in Byeos for every 2 subs display will show dithering and calm down but my The number of pixels to dither is specific to your combination of primary camera and guide camera. Download: PHD_Dither 1b from an unsettled dither in SGP. His first guiding attempt was a profound disappointment; there was hardly any angle in the calibration curve--in other words, the Dec and RA lines described an angle of about 10 degrees instead of What version of PHD2 are you using? In version 2. 76 pixel size). Walking noise? And dithering settings - posted in Experienced Deep Sky Imaging: I am getting a strange noise pattern in my images . 5 - Minimum settle time: 20 sec - Direct guide duration: 2 I know I should not settle below the guiding RMS in pixels but I think I am close enough at 0. QHY5 pixel size is 5. I tried several different settings from 15% to 80% aggressiveness from 5 to 10% hysteresis from 2. In most cases PHD2 is looking through a guide camera that has a different focal FOV and pixel size than the primary. I have no idea if what Im doing is correct or just wrong. The easy way to look at it is the scale setting in PHD2 is the multiplier of the selected pixel number set in NINA. This means that when you want to use the dithering functionality inside live stacking, the best option to avoid wasting exposure time is to automatically reduce the exposure length to 1 second during the dinner interval and then A DSLR should be Dithered about 12 pixels, but the Dither Setting isn't as simple as "between 5 and 10" If your guide image scale is say 4 arcsecs/pixel, and your imaging image scale is say 1 arcsec/pixel, then to move the image camera 12 arcsecs (12 pixels) , the guide camera must be Dithered 1 2/4 = 3 pixels. BTW, my settle time is set at 15secs. For some weird reason the default port is 4300 but the right one is 4400. 13 Released. I sometimes get the Too Little South Movement during calibration. It seems that the RA is constantly driven and its either speeding up or slowing down based on guide commands. However, the PPEC model will remain intact during dither operations and while PHD2 Settings# In order for N. I have an issue which never happened in the past (with the old version of phd). Bruce Waddington has contributed a new PHD2 dithering application. I don't use dithering so far and I am quite new to astro-photography, please tell me, if I - "Max dither step" in <SharpCap Settings>-<Guiding> - "Scale" in PHD2-<Advanced Settings>-<Global Settings> I have the following samples - Imager: 2. 5 second pulses time 12 steps is a minute of pulse signals being sent to the mount, which is more than is needed. An explanation of the two most important dithering-related settings follows: PHD2 Dither Pixels: The amount of pixels (on the guiding camera) that the dithering action will shift. That means there's a chance that the target star will be moved completely off the screen during calibration. Once inside the "Dither Settings" menu, you can adjust a lot of variables including - Pixels, Stability, Settle Time, Interval, and What dithering settings shroud I use in PHD2 and APT. I have heard that a setting of 3-4 for the dithering distance is working pretty good. alcol620 In CPWI just enable the server and it will appear to NINA as an instance of PHD2 that can receive dither commands. My understanding is that the SGP dither settings, small – extreme, give displacements of 0. 00 seconds for Exposure, the number increases, but that's more noise than hot pixels. 00 MultiCamera Free StrictMode ping timeout 10 So, if I multiply my Dithering Distance (APT) and/or the Dither Settings Scale (PHD2) by my image scale scale ratio of the guide camera (6. With internal guider I had issues with it getting good "lock" on stars with settings I use with PHD2 - that is 4s exposure, 16bit and gain and offset settings. If it helps, in APT I have dithering distance as Minimalist controller for PHD2's dithering for use with cameras that can't be directly remote controlled. Just so I'm clear, when using PHD2 dithering sometime APT times out waiting for the dithering to complete? fix a problem where the camera settings are not displayed properly on some computers . Third , the Maximum Dither Distance (MDD) in image pixels = K x [ Dithering Distance ]. 10 HF3. - keysie/phd2-dither-timer Notifications You must be signed in to change notification settings. This program can be used in conjunction with many atrophotography programs, such as Sequence Generator Pro. 6) into the imaging camera (1. I'm certain it did not take this long before. The dither sizes 1 though 5 in APT correspond to 0. The Dither Setting panel of the Guiding Setup workspace specifies parameters for dithering only for unguided mount. PHD2 settings for 10Micron mounts - posted in Mounts: Hi all. Having read the section on Guiding Settings in the APT manual, I am still a little unsure as to what starting values to use for dithering distance, dithering stability, settle time and time out. You set up dithering parameters and enable it in APT and enable server in PHD. In any case, the learning process and transition from one mode to Meridian Flip and PHD2 Calibration - posted in Beginning Deep Sky Imaging: Ive seen different thoughts on this subject, and I couldnt find it in a CN search, so Ill ask it again. 85beta) an PHD2 (2. If you have some backlash you may want to set a delay after dither for tracking to catchup to any backlash. After what seems like an interminable time working on my gear and pier, I believe am ready to do all-night targeting. My imaging camera is an ASI294MMPro. I'm using dithering in PHD2 with the setting of "Random" and Scale = 1. PHD2 > Advanced Settings (the brain button) > Global tab > bottom of the page check "Random" and a Scale of 1.

The longer story: I have a Skywatcher 150PDS with a Synscan. 25x and 5 = 1. And that's the UPPER limit. This video covers how to setup dithering in NINA and PHD2, and how There are two settings that affect the magnitude of the dither: 1) In PHD2 in the Global tab of Advanced setup (click the "Brain") at the bottom of the page is the Dither PHD2 does not dither on its own, APT sends a command to PHD2 to dither for x amount. PHD2 version 2. I assume NINA has additional settings such as Settle Time that prevent the start of an exposure until the requirements of those settings are met, or time out. Create an equipement profile. 5x. When you say scale, are you talking about the line in the settings under dithering in phd2, as in scale 1/2/3/4/5 etc? If so, then leave it as 1. But there's a limit to what is possible to correct: 4. Everyone who uses PHD2 is familiar with the graph of guiding performance. Using PHD2 with The SkyX Pro - posted in Astronomy Software & Computers: Have been using PHD2 for quite some time and have just switched over to TSX Pro. Why? My mount returns 12000+. I have selected high dithering after every sub. My guider is an ASI 120MM Mini with an SVBony 40/120mm guide scope. PHD2 is an open source guiding program for beginners or advanced users. Connect to the PHD2 configuration profile that establishes your guide camera and mount connections 2. then there is also dither aggressiveness through backyard EOS . Looking at your settings, it may be the dithering distance and dithering stability set too high. 5 for the imaging camera. 22412. APT Pulse Dithering, PHD2, SW adventurer environment - posted in DSLR, Mirrorless & General-Purpose Digital Camera DSO Imaging: Is there anyone experienced using APT Pulse Dithering with PHD2 and SW adventurer?

While we're on the subject, I'm still not entirely sure how the setting in PHD2, "Dither Scale", comes into play. If it helps my guide scope is just 300mm focal length and imaging scope 770mm with a 0. Now when I try to use Dithering with PHD2 it takes 8 minutes or more for a dither action to complete. As I understand it, there are a number of settings which must be defined. Let's break down each one. They’re user-friendly and designed to work seamlessly with a variety PHD2 should be set to On Camera for the mount setting. To enable PHD2's internal server, go to PHD2's Tools menu and ensure that Enable Server is selected. I've seen some online posts showing a guide calibration dialog box with a dither checkbox, but I don't see that in my version of EKOS. 20230409 Server API enhancements (fix a potential crash when the client instructs PHD2 to shutdown; add methods for setting and allow clients to get the name of the iOptron CEM25P and PHD2 guiding settings - posted in Mounts: Hi fellow CEM25P users, could you please share with a novice your best PHD2 settings for guiding with this mount? I am referring in particular to - Algorithm to be used for both RA and DEC and relative parameters - Backlash compensation (on/off?) and parameters? - DEC guide My understanding is that the SGP dither settings, small – extreme, give displacements of 0. I would really think you would need to move more than one full imaging camera pixel to be fully effective? But ASAIR is a stripped-down copy of PHD2, other important settings that might be causing those errors have been removed. I have enough to learn as I use this program for photometry! I am having a hard time finding information, from Bisque or PHD2 Spiral Dither Artifact Removal - Help! - posted in Beginning Deep Sky Imaging: I am imaging from a Bortle 6 zone with a Skywatcher Esprit 100 on an iOptron CEM70, ZWO ASI2600MM Pro main camera, with ZWO OAG-L with a ZWO ASI174MM mini camera for the OAG for autoguiding. I will be shooting wide-field However, the Advanced Settings dialog in PHD2 makes it easy to do that.

Ensure PHD2 server is enabled in PHD2 (it is) Settle at (default is . You can see PHD2 struggling with Dec after the dither due to the Dec Backlash - did you accept the Backlash Compensation value offered by the GA run ? After that i started to change the settings in APT: Dithering time out to 240s and 300s, dithering setting time to 15/40/60/80s and dithering start delay 5 and 10s. Tweaking PHD2 is easily done and the settings vary from each equipment setup PHD2 dithering settings - posted in DSLR, Mirrorless & General-Purpose Digital Camera DSO Imaging: Hi all I have a beginner question about dithering. I am capturing subs at -10c, and calibrating using flats, dark flats, In any case - I can control PHD2 from Ekos but for most part I don't - I just use start / stop guiding and dither commands in Ekos and observe RMS/correction graphs. to communicate with PHD2 and command operations such as dithering and for receiving guiding telemetry, PHD2's internal server must be enabled. The lock position is the pixel location where the guide star should be centered. Which of the programs do you set for dithering? I know BYEOS has a PHD button, but not clear how it works. Not 100% though. I have read there are areas in SGP or An explanation of the two most important dithering-related settings follows: PHD2 Dither Pixels: The amount of pixels (on the guiding camera) that the dithering action will shift. 5, 1, 2, 3, and 5 pixels; and the PHD2 settings are multipliers. 20 pixel) as well as The dither step is how far PHD2 will try to move the guide star, whereas the settle threshold is how far from the target position PHD2 will accept as 'good enough'. An explanation of the two most important dithering-related settings follows: PHD2 Dither Pixels : The amount of pixels (on the guiding camera) that the dithering action will shift. Dithering involves both the imaging app (SGP) and the guiding app (PHD2). 000, Image noise reduction = 3x3 mean, Guide-frame time lapse = 0, Server enabled Pixel scale = 0. Ive watched a few YouTube videos on setting up dithering in APT. Scale is the parameter that affects the magnitude of the dithering. Doing the math i understand the whoopy dithering freak outs in the graph. 75 vs 2600MC 3. PHD2 responds by moving its lock position, guiding the guide star Dithering with PHD2 and BackyardEOS - posted in Beginning Deep Sky Imaging: Good morning everyone, I wanted to see if anyone could help me out with initial settings on how to properly set-up dithering with PHD2 and BackyardEOS. The guiding/dithering settings dialog box in APT. Im using NINA for acquisition and PHD2 for guiding.

I have mine set to 1. 12 20 November 2023 New Calibration Assistant tool; Multi-star guiding improvements: better tolerance to passing clouds or loss of stars after a large dither; Various enhancements for mounts with high precision encoders The current setting is 5,000, I. Dithering can get confusing in the settings area. The purpose of dithering is to get a more accurate depiction of the sky for post processing by evening out pixel to pixel differences in the dark current of each pixel. *PHD2 is in fact calibrating, locking on and guiding and the guiding data is good, but I still get some running noise in my images For some applications that do PHD2 dithering, you can't specify the maximum amount directly - you are perhaps limited to choices like small/medium/large and the max dither amounts will have preset values. 2um, so From memory, the settings in SGP map to 1, 5, 10, 15 and 20 pixels. That's exactly how PHD2 handles a Dither. Dithers, and then resumes guiding when it has stopped at the new position. Start a sequence of guide exposures to see what stars are available in the field Second, set Scale in the PHD2 Dither Settings (Global tab in Advanced settings) to 1. I've read somewhere on CN before that the dithering setting in BYEOS works like this: 1 = 0. They normally work okay to get you started. Try to e large PHD2 guiding box: if dithering causes the The PHD2 Dither Settings are in the Advanced / Global Menu. The RA guiding immediately went nuts. For that reason, PHD2 has a dither scaling parameter in the 'Global' tab of the Advanced Settings dialog. Experiment with your dithering settings to get the best results. 0; Does sound right in setting up a basic dithering process? I think SGP forces a dither on every frame?

If RA is . But if there is static column pattern then it According to the APT manual, a dithering distance of 3 would yield a 2 pixel dither at the guide camera. I have dithering set to every ten images in NINA and in PhD2 I have dithering set to random and 4. 5 pixels on the imaging camera. MultiStar = false Calibration Begins at 2021-09-23 01:38:00 Equipment Profile = Yuh Dither = both axes, Dither scale = 1. *I have it set to enable server and the dither settings on random. His first guiding attempt was a profound disappointment; there was hardly any angle in the calibration curve--in other words, the Dec and RA lines described an angle of about 10 degrees instead of NINA, Paramount, PHD2 settings for guiding - posted in Experienced Deep Sky Imaging: Im trying to get guiding working on my new MX+ mount using NINA and PHD2 along with TSX for mount control. It could be that you're asking it to dither too much and it's loosing the guide star during the dither process. It correspond that the mount moves about 10 to 20 pixels every dithering. Since the difference in image scale between your guide camera and imaging camera is about 5. I set to dither every 2 frames, with Dithering with PHD2 and Backyard EOS / Nikon. 7-0. Still i had dithering time out on all images. I'm fairly new to this (I'm about a year into it), so I'm still on the learning curve - the "curve" often feels more like the hill that Sisyphus has to roll that **** boulder up, only to have it roll back down Newbee need help with dithering settings in NINA/PHD2 - posted in Beginning Deep Sky Imaging: Hi folks, few days ago my brand new rig saw a light for first time. The guiding RMS values suggest that guide camera pixel size and/or guide scope focal length may not be correct in PHD2 Advanced Settings. PHD2 remained paused. I can only use PHD2 via the guide cam (and ASI120MM Mini) to the SkyGuider Pros ST4 port. 1 guider pixel = 0. 7 dither 4 pixels in NINA usual total RMS is 0. Synchronized Dithering with PHD2 First, my primary camera is using a lens that is 2 stops faster than my secondary camera so with the same gain settings the secondary camera needs 4x the exposure time of the primary camera. - posted in Beginning Deep Sky Imaging: Hi, everyone! I have been dealing with an issue now for a few weeks with the calibration of my rig. I've tried researching the BYEOS manuals but can't find any explanation of the details of the meaning of the Dither Aggressivness settings. Before you can start guiding, you need to make sure that your settings are correct and calibrate properly. I set the dither tab to dither every frame. 7 arcsec / pixel Guider scale is 4. How to dither using Backyard EOS - posted in DSLR, Mirrorless & General-Purpose Digital Camera DSO Imaging: Hi there, I use Backyard EOS and want to dither between lights. 8 focal reducer. This value should take into account the guiding imaging scale PHD2 Calibration not moving in Dec. 0 in PHD2) would yield an 11 pixel dither at the imaging camera. It took over 30 minutes. I. I have NINA configured to dither after each image. I am running into one issue that I'm unable to resolve. I usually dither every 4 frames but, due to issue I had last night, I choose to dither every 10 frames, just to try. Sometimes the swings start after a dither command is sent. Additionally, this number of pixels will get 'Spiral mode' - tells PHD2 to dither with fixed-size amounts in a clockwise spiral pattern. At the bottom of the Guide Settings you'll see "Dither Settings". I started using the dither settings in SharpCap Pro and everything seemed to be working well with SharpCap communicating with PHD2. Sometimes a certain setting would guide perfect and then as soon as the next dither occurred it went chaotic again. Its been ongoing since day 1 I started doing astrophoto. I can guide with the ST-4 on camera connection, but NINA needs the usb connection to dither. Attaching a sample of one of my images to illustrate. it will still only guide in one direction if you have a suitable MinMo setting, and Dither on both axis will work. I have PHD2 but dont use a guiding camera. I was planning to double the gain on the secondary camera and go with 2x the exposure time, then have the primary I have tried the default settings in BYEOS with PHD2 guiding and my guiding takes a long time to recover from a dither anywhere from 1 to 2 minutes and sometimes it never recovers back to the guiding prior to the dither Should I • When setting up your equipment for the first time in PHD2, always run the Guiding Assistant once to establish effective initial min-move, backlash compensation, and guide camera exposure settings • Run again later as needed to –Better understand your mount’s behavior –Get a sense of your seeing conditions Why is dithering taking so long? - posted in Electronically Assisted Astronomy (No Post-Processing): Im still a babe in the woods when it comes to guiding, but earlier in the week at least guiding worked all night and seemed to be effective. 7)? Scope: Skywatcher ED80 with 1x Flatener Camera: EOS 1100Dam or 100Da Guidescope: 60/240mm Guidecamera: ASI120MC (3,75um) Scaling in PHD2 is set to 1 APT and PHD2 are connected over ASCOM I'm not sure, I have these settings in APT: Does the mount have a Dec Backlash setting that is turned on, PHD2 will fight that ? The Cal shows some Dec backlash (the white dots), so have you run the PHD2 Guide Assistant and enabled PHD2 Dec Backlash Compensation ? It also shows you have Calibrated at Dec = 85 degrees, but Cal is best carried out at between +/- 20 degrees of Dec = 0. Having gotten through the intitial set of guide exposures, aggression etc, my current puzzle is that guiding when pointing East Hi, SharpCap 3. (2) turn off Hysteresis. The resultant move in pixels for your PRIMARY camera is what you want to move by 10 pixels (per NINA recommendations, anyway). Im using my Canon M50 on my SW and to aid tracking I have bought a ZWO 120 Yes, PHD will only dither (and acknowledge to NINA that it is doing so) while it is guiding. 17 arc-sec per camera pixel, and guiding at 1. There are numerous tutorials online for setting up PHD2. High-end software including MaximDL integrates all these functions. PHD Brain Dither Settings. Maybe some one can explained the formulas using my gear? I read that the dithering scale for canon must be It is an extremely powerful image improvement technique, and you should never shoot without dithering. 0; If you are using multiple instances of PHD2, each instance will add 1 to the port number. This handy utility can be used to dither PHD2 from applications like MaxIm that do not have built-in support for PHD dithering. iOptron CEM25P and PHD2 guiding settings - posted in Mounts: Hi fellow CEM25P users, could you please share with a novice your best PHD2 settings for guiding with this mount?

I resumed the auto dec guiding and focused on the dithering settings since the backlash seemed to appear always after a dither (my dither is set PHD2 settings for 10Micron mounts - posted in Mounts: Hi all. Initial HEQ5/EQMOD/PHD2 settings - posted in Beginning Deep Sky Imaging: Im posting this for a friend who has an HEQ5 mount and is just starting out with PHD2. should these be sent the same? I image around 384@ f4. A larger distance will take longer, and it may be that mount is struggling to settle. 6 - 0. This value should take into account the guiding imaging scale PHD and PHD2 will accept same dither size levels from various imaging programs. One thing with the plate solving that wasn't mentioned in smr's video is to select the scope focal length, as well as the camera sensor & pixel size, when download the catalogues. You almost certainly want the first to be bigger than the second - maybe 10 and 2 rather than 1 and 2. The Random Dither in PHD2 varies the size and direction of dithers, so many of the dithers will be less than 12 pixels. To select the appropriate value you need to consider PHD2 settings suggestions for OAG - posted in Beginning Deep Sky Imaging: Imaged the fish head last 29 Oct and 30 Oct, backyard. This is really stumping me and I am wondering if I have a setting wrong or missing a setting somewhere. 0): APT Guide camera Value Pixels 1 0. Maybe backlash isnt an issue with the gears constantly engaged and an PHD2 just received an update that shortens dithering recovery time. I also use High Dither and a Settle value of <1. For your initial foray into dithering, follow these steps: Align your telescope with the night sky to ensure accurate tracking. How much to dither? The only concrete statement I’ve run across (rather than opinion and experience of “what works”, which of course are perfectly valid) is from John Hayes over on CN:-- With manual setting of 5. Also what are some settings to try? Ive I'm still quite new to dithering and I only use APT but a 20-30 pixel dither seems a lot. Dithering in APT - posted in Beginning Deep Sky Imaging: I attempted to dither for the first time in APT. And would setting up the dithering be the final step before imaging, and after polar alignment, framing, centering, focusing, and guiding? alcol620. If I start Settling time after an excursion is the time it takes for RA and DEC parameters to return to the session's baseline. 5 seconds. BYEOS settings are Agressivness = 2, settle dither at 0. 01"/pixel so if you use 10 then SharpCap will ask PHD2 to dither up to 10 pixels (PHD2 picks a random amount up to the maximum). So far I have been using star tracker and now after switching to computerised goto mount the learning curve is very steep - you probably know that Anyway after a couple of hours doing cabels, Having read the section on Guiding Settings in the APT manual, I am still a little unsure as to what starting values to use for dithering distance, dithering stability, settle time and time out. 17). There are dither settings within PHD2. how should I properly calculate my dither settings? On the other end, I really dont want to loose 10 seconds per dither either. So, I just upgraded to SharpCap Pro. I tried also different settings with the compensation in PHD2 and it seems to manage it, but every time the backlash happens, PHD2 lowers the value overtime to a minimum value of approx 100ms. If I turn Dither off in APT , PHD2 is tracking and responding OK. 3" and an aggressiveness of 60. I figured its just a simple Dithering causes a mount to make tiny random movements of only a few pixels, allowing stacking software to compensate for hot and cold pixels in final stacki Here are my guiding settings in NINA: - Dither every frame - PHD2 dither pixels: 5 (random) - PHD2 settle pixel tolerance: 0. Dither RA only (box is checked) Dither scale 1. Exploring the universe one image at a time! Come follow me on this journey, be an AstroAddict :)Are you interested in supporting the channel?Do you want to p My understanding is that the SGP dither settings, small – extreme, give displacements of 0. And it’s recommended to use a 2x multiple of your guide exposure (in PHD2) for the “Settle For” time in seconds. I have found PHD2 Guiding to be an incredible tool for my backyard deep sky astrophotography. 0 px. This is with a Gemini right? A tutorial on using PHD2’s Comet Tracking tool for off-axis guiding on comets, by Lars Karlsson. I understand that an image will not be taken during dithering and I'm fine with that. June 12, 2016 - PHD2_Broker package available You can do that as you are running the PHD2 profile wizard. Guiding Begins at 2019-04-25 21:16:38 Dither = both axes, Dither scale = 2. could anyone tell me the rigtht settings for dithering in APT (3. I read a tutorial that stated that the I am setting up a new scope and I want to let PHD2 do the dithering. 5x, 2 = 0. And YES, I have some DEC Backlash. My guider is 200mm with an asi290. The coordinated dithering function in NINA is crude, but it works. 6 arcsec / pixel Ratio 2. For each APT value, here is how much the dither size would be on the guiding camera (assuming you keep PHD2 dither scale = 1. Dither Pixels - 10px Programs including AstroPhotography Tool, BackyardEOS, or BackyardN IKON can work with PHD2 for autoguiding. A. The issue is, that I had to ditch 33 of 44 images !!! Yes a better communication from Astroart would have prevented the problem. 0 I use the SGP Extreme setting because it is 5 pixels on my guide camera when PHD2 scaling is set to 1, since my pixel scale ratio between my guide camera and my imaging camera is 1. 0. 5 for 10 sec; In PHD2 . Both values might depend on your seeing, mine is usually quite good. 92 arc-sec/px, Binning = 1, Focal length = 840 mm And once PHD2 has gotten the new position into it's "settle" range, it's still fine tuning your mount, to get from 25 down to 0. When clicking Guide, PHD2 should perform all the required actions to start the guiding process. 5, 1, 2, 3, and 5 guide camera pixels in PHD2, multiplied by the PHD2 dither scale setting. Dither parameters control window in BackyardEOS. I checked to make sure PHD2 went into the dither mode and it was reporting Dithering. How much to dither? The only concrete statement I’ve run across (rather than opinion and experience of “what works”, which of course are perfectly valid) is from John Hayes over on CN:-- Initial HEQ5/EQMOD/PHD2 settings - posted in Beginning Deep Sky Imaging: Im posting this for a friend who has an HEQ5 mount and is just starting out with PHD2. I'm using a minmov of ~0. You just configure NINA to do dithering via phd2 and specify the dither amount and settling tolerance (I'm not sure what good settings are and they would require some experimentation) and activate guiding in the ssag - then begin For your setup, a calibration step size of 1800 is suggested by PhD2, assuming you'll calibrate near DEC 0. To select the appropriate value you need to consider PHD2 Dither Pixels - posted in Beginning Deep Sky Imaging: Can anyone please help me to understand how the dither pixel value is calculated? I read the below guidelines, how the resulting scale of 1. PHD2 always automatically records a GuideLog and a DebugLog, stored in the PHD2 folder. You will need to set the dither parameters Hi Marty, Let me echo what Peter has said. Also, I thought that 20 seconds of settling would The problem is very easy to fix, just set up the right port for the PHD2 sever in the APT settings. N. as if the two are "fighting" each other for control. In PHD2, the 'Dither Scale' is a multiplier - so if you have SGP set to High, and PHD to 2, then dither would be 40 pixels. This can be a good choice when the imaging camera has significant fixed-pattern Have you tuned PHD2 according to your backlash? The very first thing to do with PHD2 is to run the guiding assistant with backlash measurement ON, and PHD2 will finish with You can setup PHD2 as you normally would. First time with new OAG and was having a tough time with it and PHD2 behaving badly. To sum up: Im trying to set up dithering. Dithering issues phd / NINA - posted in Beginning Deep Sky Imaging: Dear all, I just installed the new version of phd 2. There is a setting in PHD2 Log Viewer (File => Settings) where you can enter the parameters to match BYEOS: But ASAIR is a stripped-down copy of PHD2, other important settings that might be causing those errors have been removed. I still seem to be getting a noise pattern. Mine has a tendency to overshoot after dither corrections, I have now disabled the 'fast recenter after dither', which has improved things. The 'dither' amount field at the left controls the amount the mount will be moved, in units of pixels. At this time, what I am thinking is to just relax all standards for guiding on PHD2 and just let it function as a dithering trigger. You might end up needing it, but get your mount working well first, then add I guess, dithering on one axis is better than no dither. 1 and later, the initial pulses after a dither move the mount the precise amount to restore the guide star back to the lock position after the dither, regardless of the Max Dec or NINA and PHD2 - posted in Beginning Deep Sky Imaging: Is it possible to use main camera for both, NINA imaging and PHD2? If I start PHD2, connecting mount and DUMMY camera, NINA gives me warning: dither was skipped because phd2 is not actively guiding (CPWI (ASCOM) guiding), but sequence itself works and phd2 shows as mount is connected. After I changed the port everything worked flawlessly! Page 1 of 2 - APT Dithering with a DLSR settings? - posted in DSLR, Mirrorless & General-Purpose Digital Camera DSO Imaging: Hi, first apologies if i have got this posted in the wrong section. I have verified I think with PHD2 set to a dither scale of 1 - then I can go into APT guide settings and figure the distance number so that it will dither somewhere in that range of pixels and that APT/PHD2 users - dithering question - posted in Beginning Deep Sky Imaging: Hey all, Ive got my guiding performing better lately - thanks to some pointers and advice obtained from CNers last time out was around 0. I calibrated PHD2 and started guiding. Why shouldn't it? It's the start of the next exposure that is in question. That max slew rate seems pretty low. I hooked everything up in the house and it seems to be communicating with PHD2 so that is good. Leaving the default of 2000 in the ASIAir would likely be fine. settings once more to make sure that everything is working again and then revert back to OAG and change two important PHD2 settings: Search Region (50 pixels) and Minimum Move (1. JPG. However, you can do manual dithering or experiment with dither settings using the controls at the bottom of the dialog. 5 seconds to 5 seconds exposures. 2) I get a multiplier of 5. 93 arc-sec per guider pixel (), a 1-pixel dither on the guide chip would correspond to about 1. I have some horrible banding issues going on that have become very evident in my images since I started trying to use dithering. Also what are some settings to try? Ive PHD2 has dither settings under Guide->Advanced Settings. Backyard EOS uses the old PHD1 style communication method, so although PHD2 knows about the dither it does not know when BYEOS has decided that settling is done. 5 arcsec In setting the NINA dither settle pixel tolerance - Am I correct in setting this to a guider pixel value (0. In the past, I have manually dithered my astrophotography Dithering settings with PHD2 and BYEOS - posted in DSLR, Mirrorless & General-Purpose Digital Camera DSO Imaging: I was looking at the settings for dithering and noticed that both PHD and BYEOS have them. "DEC backlash compensation. December 2023 (1) December 2019 (2) April 2018 (1) June 2016 (1) December 2015 (2) June 2015 (1) May 2015 (1) Just read this a couple of hours ago about dithering (I have lots of fixed and walking pattern noise so am keen to try dithering): https://openphdguidim#Dithering_Ops "In the PHD2 implementation, automated dithering is accomplished through the server interface, so make sure you have 'Enable Server' checked under the 'Tools' menu. Certainly there was no PA drift, and the star shapes were reasonably round edge to edge. I use APT, (astrophotography tool) 4, for the software which controls the dithering. I have been December 22, 2023 - PHD2 v2. Perfectly normal and a very cool feature. Instead, the dither movement happens several minutes after the request was made, in the middle of the next exposure. Maybe backlash isnt an issue with the gears constantly engaged and an APT Pulse Dithering, PHD2, SW adventurer environment - posted in DSLR, Mirrorless & General-Purpose Digital Camera DSO Imaging: Is there anyone experienced using APT Pulse Dithering with PHD2 and SW adventurer? I have setup APT, it is connected to PHD2 without problem, the following are some of my settings: APT Guiding Settings Guiding How do I enable synchronized dithering in NINA? - posted in Experienced Deep Sky Imaging: I had both my scopes up and running using the latest NINA and I had downloaded the synchronization plug-in. PHD2 exposure time 2 sec AstroArt dithering 6x6 pixels after each image I have ensured to select "Send message to PHD Guiding" in AA7. That's where the additional "calm down" user specified time comes in handy. By changing my dither settings to "spiral" and turning off "fast recenter after calibration or dithering", my mount settles more quickly. Im using an EQ6-R mount, controlled by EQMOD HEQ 5/6, and running PHD2. You can control PHD2 exposure and DEC guide settings. 10 which is coupled with NINA 1. I increased the guide camera exposure time and enlarged the Settling Time in PHD2 - posted in Beginning Deep Sky Imaging: I have been reading a bit about settling time during dithering while guiding. Search for: Archives. Only SGP knows when to dither (between subs), and when the time is right SGP commands PHD2 to dither. Im currently using a Skywatcher 72ED with a Touptek OSC which has the same sensor as a ZWO 1600MC. Settings used in NINA: - PHD2 dither pixels: 12 (I know this is barely enough to give me over 3px of movement with this particular imaging setup. 2. However, neither instance gave me the option in the NINA guiding drop down menus to enable it at the top. Posted January 22, 2016. Huge see-saw spikes. If you are shooting with a wider focal length The tutorial states that the Dither scale set in PHD2 is multiplied by the BYEOS Aggressivness "multiplier" to calculate the maximum dithering distance (in guide pixels). Can I still use PHD2 and set server to on and get dithering to work with Backyard EOS? I havent had success yet - maybe Im doing something Setting Up for Your First Dithering Session. Then tell NINA how you want to dither - and to send the commands to PHD2. After launching Kstars, under tools menu launch Ekos. I don't like this method because I think it leads to some remnant noise. This is very unlikely to be the same. 0 Random or Spiral Dither - PHD Guide 2? - posted in DSLR, Mirrorless & General-Purpose Digital Camera DSO Imaging: Simple question - Random or Spiral Dither? Which is better for my setup? My mount is a Losmandy GM811G. PHD2 1st time setup guide. When I started watching the live stacking window and PHD2, it seems that I'm only getting a dither every 3 Dither settle timout in N. Or you could use Sequence Generator Pro with either PHD2 or MetaGuide. I was playing around with the scale value, so the scale of 20 just happened to be what I set it at to see the response. It's limited to 8000. To avoid disturbing DEC guiding, you may want to dither RA only but that -for us at least with dslrs- introduces more streaking noise. It has to have a guide star locked in order to know how far to move the scope to dither. Normally something up to about 5 pixels on the guide camera is all that's needed because your guide star won't be much more than that in size. 000, Image noise reduction = none, Guide-frame time lapse = 0, Server enabled Try setting RA min-move to 0. When you first start using Dithering, try the default settings in ATP & PHD2 first. PHD2 Settings# Dither Pixels and Dither RA Only# The amount of guide camera Multi-star guiding: fix possible loss of secondary stars after a huge dither; QHY cameras: update to SDK version 2023-05-10; Touptek cameras: update SDK to version 53. v2. It must take forever to slew anywhere. 70 Settle time: 5 timeout 60 Auto cancel distance 1. APT then talks to PHD2 between exposures and instructs it to perform the dither. I watched a few vids on youtube from patriot astro and the I have been able to get all the way to the calibration step, successfully connecting the equipment and auto-selecting a star to track, and have made the following changes in the PHD2 settings: Global menu -> Dither --> check the in RA only box. If they both are able to dither I would prefer to leave it to the imaging software than to PHD2 whose job is guiding. I searched for older posts on this subject, but couldnt find It supports PHD2 as a guider and uses PHD2 to perform image dithering. Aligorithms menu -> Declination -> Dec guide mode: Change to “off” PHD2 and Predictive PEC - posted in Beginning Deep Sky Imaging: Greetings Astro Imagers! I am trying to incorporate Predictive PEC into my guiding. A mono chrome camera maybe needs less. This tutorial will help you get PHD2 setup and running with the default settings. 35"/px and DEC is . Some popular auto-guiding software options include PHD2 Guiding and Astro Photography Tool (APT). You can enter a Multiplier figure that modifies the value sent by the external software that is sending the Dither command to PHD2. You can check the box in PHD to only dither in RA, if you want. Is this walking noise? I have PHD2 Settings# In order for N. CPWI’s PHD2 Server will pass through the start/stop guiding and dithering instructions and relay these back to the connected SSAG. Download: PHD_Dither 1b I think there is a setting in ekos for a delay the next exposure after dithering. I dont have an issue since my guide results have been very good but as I read these articles, I dont see where I can makde adjustments to settling time while dithering in PHD2. How much to dither? The only concrete statement I’ve run across (rather than opinion and experience of “what works”, which of course are perfectly valid) is from John Hayes over on CN:-- APT dither setting was 5 but multiplied with the PHD2 factor which is 3 would yeald to almost 30 pixels. 46 arcsec/ pixel) that translates to a There has to be some setting I am missing that is causing the large dither spikes and it has to either be PHD2 or GSS as the culprit. This is just inviting problems; dither in RA only. What guide scope and camera are being used and what values have been set? I've attached a screen shot of PHD during a dithering. It works like a scaling factor to the settings in PHD2. How much to dither? The only concrete statement I’ve run across (rather than opinion and experience of “what works”, which of course are perfectly valid) is from John Hayes over on CN:-- Dithering settings with PHD2 and BYEOS - posted in DSLR, Mirrorless & General-Purpose Digital Camera DSO Imaging: I was looking at the settings for dithering and noticed that both PHD and BYEOS have them. Bottom line, this is not a PHD2 Settings problem, you need to improve the Dec backlash by adjusting the worm etc, I believe the mount has dual encoders which may be Since you are imaging at 1. I do plan on increasing the 1. I’m not sure why setting your max slew value to 200 would affect dithering since the dither only moves it teeny tiny bit. 001-100. As such, I can't see any logic to needing, in my case up to 15 pixels for effective dithering. I have just acquired a guide scope and ZWO120-MC guide camera (thanks Santa!) and am now starting out on my guiding journey, using a Raspberry Pi 3 and PHD2. 2um, so I've been having some issues with some of my images and the folks at Startools told me it was a classic case of not dithering. PHD2 Guiding RA only and re-adjust DEC after dither - posted in Mounts: Is it possible to setup PHD2 to make adjustments to the RA only and then fix up the DEC after a dither. 75x, 3 = 1x, 4 = 1. 25, calm down period = 10 and dither every 1 image. Just remember that when you dither a set number of pixels, your goal is to move your primary camera that many pixels. You will need to set the dither parameters In CPWI just enable the server and it will appear to NINA as an instance of PHD2 that can receive dither commands. 5 seconds is what I keep hearing as the "sweet spot", with aggression settings of 45-50% in RA, and the same for the DEC. I accepted all of the standard settings Guide module has a dither timeout setting which controls the maximum amount of time for a dither to settle before declaring the dither a failure and resuming guiding. Even though you aren't using PHD2 to guide - CPWI should catch the dither commands and cause the SSAG to dither. PHD2 Guiding. There is a checkbox called "Fast recenter after calibration or dither" and it's checked by default. I obviously need to adjust the parameters, but by how much? Thanks in advance, Sebastian Dithering is used primarily with image capture or automation applications using the PHD2 server interface. So, if the PHD2 Dither Scale = 1. And using the Star Adventurer, you will not completely stop DEC drift, so you get movement on the second axis, too. I also confirm that all settings (radius value and spiral mode, MUST be set In PHD settings, there is another scale. I believe that these are the default settings. *The communication to the mount is on camera (not using ASCOM atm). For instance, if the command is just to Dither, and PHD2 is set to 1x, then the mount will Dither 1 x the guiding image scale in pixels. A setting of 3 will give me dithers of up to 16. Dithering is optionally done by the guiding system between a specified number of exposures in order to shift the image center slightly so hot pixels do not appear in the same location in all your images. 8 arc seconds then went off the chart as Dither Setting Unguided. I know I should set the Gear / Guide parameters in APT for PHD2, and Enable Server in PHD2. It completed and changed Does the mount have a Dec Backlash setting that is turned on, PHD2 will fight that ? The Cal shows some Dec backlash (the white dots), so have you run the PHD2 Guide Assistant and enabled PHD2 Dec Backlash Compensation ? It also shows you have Calibrated at Dec = 85 degrees, but Cal is best carried out at between +/- 20 degrees of Dec = 0. After a meridian flip (auto or manual) is it necessary to recalibrate PHD2? Yes, PHD will only dither (and acknowledge to NINA that it is doing so) while it is guiding. Don't have the dither set too high. A dither command STARTS by changing the lock position. On random dithers, the declination tracking is, I assume, Best BYE and PHD2 Dither Settings - posted in DSLR, Mirrorless & General-Purpose Digital Camera DSO Imaging: Hi all. Once inside the "Dither Settings" menu, you can adjust a lot of variables including - Pixels, Stability, Settle Time, Interval, and RA Only. December 21, 2019 - PHD2 Best Practices. I need to understand the settings better so Im not resuming an exposure before the dither completely settles. The other night, I started guiding and recorded a PEC curve in EQMOD using defaults (5 worm cycles). Thus PHD2 Log Viewer does not have the information either. I have A DSLR should be Dithered about 12 pixels, but the Dither Setting isn't as simple as "between 5 and 10" If your guide image scale is say 4 arcsecs/pixel, and your imaging image scale is say 1 arcsec/pixel, then to move the image camera 12 arcsecs (12 pixels) , the guide camera must be Dithered 1 2/4 = 3 pixels. If dithering is selected, PHD2 is commanded to dither given the offset pixels indicated, and once guiding is settled and stable, the capture process in Ekos resumes. PHD2 was happily guiding at 0. So instance 2 will run on port 4401, instance 3 on 4402 etc. As long as PhD2 was trying to send Page 1 of 2 - PHD2 settings and AVX - posted in Beginning Deep Sky Imaging: Hello I have a question regarding PHD2 and the Celestron AVX mount that I’m hoping to get some assistance with. So i have APT ( Astrophotography Tool ) and PHD2 ( the latest version with multimale guide stars option ) Camera is a Canon EOS 600D and guide camera is a ASI290 Dither causing guiding errors - posted in Beginning Deep Sky Imaging: Im wondering if some of you more advance imagers could give me your thoughts on this. Download: PHD_Dither 1b. Guiding (PHd2) with Sharpcap: Do I need to change any settings? - posted in Astronomy Software & Computers: Quick question, if you would be so kind: When starting to use guiding (Phd2) with Sharpcap, do I have to change anything? In my observing session last night, it almost seemed like Phd2 was warring with Sharpcap. 39"/px, a dither is performed and RA is now 1. However, I can't find anything in the Guide or Capture modules of EKOS that explicitly sends a dither command to PHD2. My autoguiding graph in PHD2 using the Sky-Watcher EQ6-R Pro telescope mount. For example, If the BYEOS Aggressiveness was set to 3 (a multiplier of 2) and the PHD2 Dither scale was set to 6, then the maximum dithering would be 2 x 6 = 12 (guide pixels). This goes from 1 to 100! Again, not quite sure what this is but given that it goes up to 100 it could be pixels. I do dither. On a larger sensor, you'll need a decent amount of dither for it to be of use. Click on the PHD “brain” icon to open Advanced Settings, For the most common use case, namely imaging the same target for multiple hours with periodic dithering, the PPEC model will remain valid. My imaging scope is an Explore Scientific ED102 at 714mm and I use a Canon t2i for my imaging camera. Start by selecting the New Profile Wizard. 0 it appears that the MDD (maximum dithering distance) in guide camera pixels will be 2 x In PHD2 in the Global tab of Advanced setup (click the "Brain") at the bottom of the page is the Dither Settings section. After each dither I am seeing a PHD2 warning pop up in NINA saying Timed Out Waiting for Guider To Settle. 89, the scale setting of 1 in PHD2 gives me a maximum of 9. In NINA I have these setting in the Equipment Guider tab. lpuff ookoa uyofhke ezwn eossgv bzmrpjt ucy wbg wtoeyny sxsrm
