Re: APCC 1.8.3.1: strange behaviour when parking at Park1 position


Yves Laroche
 

Ray,

I can assure you that my computer clock was well synchronized.  It's part of my ritual before any imaging session since a long time.  If you read carefully my latest message, I unparked the mount from "Last Parked Position" (It was Park5 instead of Park1) and parked the mount again to Park1 and it worked.  NO possibility here of time issue.

I've just remarked that CP3 is set within ASCOM driver instead of CP4.  I really don't know why but... Is it possible that this setting can raise some problem with the new APCC release???  I will find this out at the end of the incoming night.

Regards,
Yves

Yves,

Nothing has changed regarding Park 1 in a long time in APCC.
