Hello,
Lately I'm having issues calibrating my AVX mount in PHD2, via ASCOM.
The guide star never seems to move enough, regardless of whatever setting changes I care to make in PHD2.
Some weeks ago, I started noticing my tracking was terrible, even with short subs, good balance, polar alignment and cable management.
I have made no hardware changes and my rig has previously worked without issue for many months/years.
Over the course of the past three days, I have tried:
Changing cables.
Changing the Autoguide rate in the handset (and PHD2) from 50 to 90%.
Turning the Anti-Backlash setting on and off.
Updating ASCOM platform from 6.5 to 6.6.
A spare laptop running a previous 100% stable build of PHD2.
Running ASCOM wirelessly, via Celestron SkyPortal WiFi adapter, without the cable and handset (Celestron CPWI).
Using a Shoestring Astronomy GPUSB adapter.
All without success (the same issue every time).
But when I switch to calibration and guiding via ST4 cable, everything works perfectly. Ultimately, I need ASCOM over ST4 for my automated imaging plans.
The mount is physically good order and under normal circumstances, autoguides great.
TBH, I'm now at my wit's end and don't know what to look at next.
Here is my log
Many Thanks,
Kevin
