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.
I am currently researching which setup to purchase as my first proper scope (once they are back in stock).
I thought I had settled on the Skywatcher Explorer 130ps AZ GTi but then I saw the Skywatcher Star Discovery 150i for just a little more money.
Could anyone please tell me the difference between the 2 OTA's (other than the different aperture size), and also the difference between the 2 mounts?
I realise that the AZ GTi can be modified to run in EQ mode whereas the Star Discovery can't.
Can the Star Discovery view all the way to the zenith or does the OTA catch the mount or tripod before it gets there?

Hi! I purchased a Raspberry pi 4 4gb not so long ago with the intention of running a NAS and some other stuff on it. I have since then considered the possibility of using it to control the alt/az position of a mount like the Skywatcher AZ GTi with a python script running on the raspberry pi. I haven't purchased the mount yet since I'd like to hear if it would be possible.
A little more information on my main objective:
Weather satellites and radio has recently caught my attention and I'm therefor considering to mount a directional antenna on the skywatcher AZ GTi mount which then tracks a chosen satellite across the sky. The raspberry pi would be running a program that would send the alt/az coordinates to the mount. I have thought about sending the alt/az coordinates through a TCP socket but I'm not sure how I would connect (and if it's possible) the mount to the raspberry pi or the opposite way.
Here's a video of the current software I'm working on:
I've seen people control mounts like the Celestron nexstar ones but it would be ideal to make the small and light weight AZ GTi perform the same job. If you have any experience with the AZ GTi mount and raspberry pi I would highly appreciate your advice:)
Thank you in advance!
Can confirm my second project with the lattepanda has been a success. 😁 Chuffed to bits,
Flashed my az gti to the az/eq firmware
Installed,, CdC, Ascom, eqmod onto my Windows 10 laptop. Plugged az gti eq mod cable from FLO into laptop and azgti, configured to cdc and eqmod,, azgti now controlled via cdc..
Disconnected the laptop,, plugged the lattepanda in its place,, had to reconfigure comm port,, working via lattepanda now,,
Last bit of the project,, install tight vnc on laptop,, put in panda ip address,,
Laptop,, lattepanda are connected to my smartphone hot-spot.
I now have wireless remote desktop control of the panda,, eq gti / eq panda is born,, 😁
since i started work on my observatory there hasn't been much time for AP, but since lunar photography is done in minutes i had a go yesterday.
SW AZGTI with the Skymax127 and Sony A6300 and Baader Neodymium Moon & skyglow filter.
