I have a usually reliable AP1600 mount.
It is slewing fine but autoguiding suddenly went wild a little while ago.
So normally I get very small guide errors .2 to .6 arc sec
guide errors. They suddenly went to 15-20.
I couldn’t get it to callibrate either using relays.
I switched to pulse guiding and I could callibrate.
But guiding is still wild. I tried various settings
for the guiding.
I pulled apart the electronics box and inside it looks lile
I noticed in the driver you can set the guide rate and it was set at 1 so I reduced that to .5 and I can set it lower. I will disconnect the hand controller
tonight in case that is having an effect.
I am using SkyX, ascom mount and the AP driver. Its an AP cp3 electronics.
I am able to do plate solving, polar alignment using TPoint so go to’s are working.
