Not trying to hijack the thread.... I'm doing a polar alignment on a pme atm.
I seem to get pa elevation with a consistant result of under an arcminute out, I think from memory around 50 seconds from the true pole. But azimuth seems to fluctuate, there is no pattern in the tpoint model that tells me that there is a mechanical problem. I ended up doing a drift align and adjusted till I was getting no pixel drift in 10 minutes (.86 arc sec per pixel). Tpoint still tells me that I am 2 minutes out.
I guess my questions are;
How many arc seconds out do consider a good polar alignment?
How consistant are your result from a 30 point models? (eg within 20 arc seconds etc)
Thanks
