Don't know what happened with my drift alignment 2 weeks ago.
I used the polarscope, and my laser on the SCP method. Checked it on the lappy for accuracy and it was lovely. All GoTo's were spot-on all over the sky, and no drift over 1/2 an hour with Autoguiding turned off.
Then I did a drift alignment.
It was sooooo close it wasn't funny, but I wanted to practice, so I moved the mount a smidge in both Alt and Az. Then after about 2 hours of verrrrrry fussy drift aligning, I once again had no drift for well over 20 mins
I re-started the whole 3 star alignment again. For the rest of the night it would not do accurate GoTo's and Autoguiding was chasing all the time. It was hell to image!
I re-did my original method and all GoTo's were spot-on again
I think I'll stick to my laser method and give the Drift aligning away
