Well, tonight was even worse. I tried 4 different pairs of stars over a period of nearly 3 hrs, and when below 1 deg of error I would get nonsensical readouts, and the scope would miss the next star by 10
or 11 degrees. On the fifth pair, [Rigel and Canopus], I eventually got down to less than a minute of error on both axes, but the best tracking
I got with my 80mm f/5 refractor was 20 secs on M42, and barely 15
on NGC 2070. I normally get around 200 secs with this scope. I have
no idea what is going on. If this carries on I might give up imaging, and
get the trusty 10" Dob out.
