Hi, first post so please bear with me, having issues with autoguiding, looked at numerous forum threads and cannot find the issue specific to my setup and the issue I am having.
Equipment in question:
ZWO 224 using as guide camera plugged into raspberry pi running Astroberry via USB3,
Lynx Astro EQDIR cable plugged from USB on raspberry pi into hand controller port on AZ GTI.
Synscan android app successfully connected to AZ GTI via wifi and can control via mobile phone,
AZ GTI setup to connect to raspberry pi (so it's on the raspberry pi network) AZ GTI connected successfully as it is recognised in PHD2 and EKOS,
In PHD2 the mount is setup as INDI mount (AZ-GTI) and connects.
PHD2 is unable to guide in either RA or declination (see screenshot error showing up), it is always one or the other. I have tried setting up multiple times, tried using the network cable which came with the camera directly from the camera into the hand controller port and setup in PHD2 as "on camera" (I suspect this setup is wrong anyway and was one of the first I tried). Polar alignment has been checked multiple times, the end result is always the same, the star field within PHD2 window will always drift in one direction so any star chosen will eventually disappear out the field of view as the mount isn't moving to follow it.
Looking at the PHD2 graph I know it is trying to send pulses to the mount but either the movement is too much for the mount to move or something isn't happening as it should, in the example screenshot provided I tried this indoors on a fairly fast (compared to in the field) rotating star field looking at a screen so it will fail, though the mount didn't adjust at all, no matter how I've setup prior the AZ GTI refuses to adjust to follow a guide star. I have tried manually moving the mount in PHD2 and it doesn't seem to move in any direction, manually moving however does work in EKOS so the hardware seems to be plugged in correctly. EKOS even knows where the mount is pointing and can issue go-tos (although it is slightly off target at the moment).
I am kind of at my wits end to why autoguiding isn't working, if anyone can help please assist.
On another note if someone can advise how to configure PHD2 so the off yellow warning box colour can be changed so the error message can be read clearly - I know theres a line of code I can use in the terminal window which refers to a resource file to change to the default PHD2 colours and launches the software but the changes are never saved.
Hi guys I have a few questions
I've recently upgraded to an ASI533mc pro from a DSLR. As I am living in the southern hemisphere and in bortle 6 light pollution, I don't have site of Sigma octanis to get a rough initial polar alignment and previously found that using the reticle feature on my DSLR live view with the synscan polar alignment routine, I could get quite accurate polar alignment in 5-10 minutes (180second unguided subs with around 80% keepers, I don't trust the estimates but under 2 arcminutes generally) My initial setup is usually 3 or 4 degrees out in azimuth.
I had a go with phd2 PA last night without much luck, I'm assuming because my initial setup was more than a couple of degrees out. I'm happy to just use the synscan routine as I can complete it quickly enough and achieve a good enough alignment, especially now that I'm guiding, and it would seem I would have to run a few iterations of it anyway to get my initial setup close to simulate you lucky northerners with your bright polaris in the polar scope. So my question is, what is a decent piece of software with reticle live view to use with my Asi533mc pro? I currently have NINA, ASI studio and PHD2 installed and I couldn't figure out how to superimpose a reticle last night.
Also, Sharpcap pro seems to be the most commonly recommended software for polar alignment. However I am using an SCT telescope and a smaller sensor camera so my field of view doesn't meet the requirements stated by sharpcap. Has anybody tried using Sharpcap pro PA at 1500mm and 945mm (f6.3 reducer) with any success?
Besides drift alignment, which would take longer than the synscan routine for me, are there any other pieces of software that I should try that won't cost an arm and a leg?
I'm running an HEQ 5 with a Celestron 6se using an Asi533mc pro imaging cam with an ASI290mm mini on a ZWO OAG for guiding.
I'm open to suggestions for other software to use for imaging, I only installed NINA because the functionality and price point is amazing, and it gets rave reviews.
Thanks in advance wonderful people!

Hi, I'm new to this whole auto guiding thing so bare with me!
So I have a iOptron SkyGuider Pro with a WO Zenithstar 61 and recently bought a ZWO ASI120MM Mini and guide scope to have a go at auto guiding. I followed tutorials online step by step (installing drivers, and changing the settings in PHD etc.) and managed to connect the camera and mount in PHD, start looping exposures and select a star. But when I start the calibration, it counts to 'west step 61' and comes up with "RA Calibration Failed: star did not move enough"
I have tried reinstalling all drivers/software, using a different laptop and solutions other people have found do not help. Guide scope is focused and it's not trying to track a hot pixel.
The star is supposed to move up and down as the mount moves during the calibration although nothing happens. So this makes me think there is something wrong with the mount or the ST4 cable from the camera to the mount. Cable securely clicks into both ends. I have heard the term "backlash" with mounts and not sure if this could be the cause? Not sure what this means or if this is possible with a star tracker?
I can't seem to manually control the mount in PHD although I'm not sure what I'm doing. I can however, manually press the buttons on the mount itself and it moves fine.
I've attached pictures of my setup along with the 'Guide Log' that people often ask for - PHD2_GuideLog_2021-08-23_225305.txt
(Also, the total weight on the mount is 4.7kg and the max payload is 5kg for imaging so this should be fine?)
Any Ideas? Let me know if you guys need anything else.

I have graduated to APT and for the most part it is working. I can plate solve and autofocus with a skywatcher 150p and canon 550d. Pictures are also fine.
The issue I am having is with dithering and PHD2. PHD2 works find with other software but for some reason, despite playing with settings I cannot get it to dither properly with APT. Issues have been:
• the dither starts but does not stop;
• the dithering stops after the new exposure starts;
• APT says the dithering has stopped but the graph on PHD2 seems to suggest it hasn't.
I have seen other threads and have played with settings but am having no luck. Any inspiration would be greatly welcomed!
