Marcus & Greg (& other PME users),

How good is your poining accuracy after power-down and power-up between nights?

I'm finding with my current model it is off by about 180 arc seconds (consistently - across whole sky). With a previous model it was only off by about 30 arc seconds, but I did probably only try it a couple of times back then.

From what I understand I shouldn't need to do a shot mapping run and also should not sync. Yet at the start of a night I need to some how tell it "tonight, you're 180 arc seconds off - move north 180 arc sec and you'll be right for the night!" - exactly a sync.

Wondering what others find.

Thanks,
Roger.
