I am configuring a setup in order to observe exoplanets transit:
Mount Ioptron GEM28
Mak180 F/D 15 F=2700
ASI183MM PRO for imaging
QHY224C for guidng on Orion finder 9x50 with a barlow x3, so F ~ 570, F/D ~ 11
The guiding calibration doesn't complete. It fails on AD reverse always. The AD motion on the graph is always in the same direction, never reverse.
I check the mount but nothing.
This is not going to help you at all but I had experienced the exact same behaviour many months ago. I never got to figure out what happened. But for whatever reason the next time I used my rig it had disappeared. Just like that. Without changing anything, no software update, no hardware changes.
