The best info to take away from the presentation is that the 2 major sources or error. ie Polar alignment and PE can and should be controled first. The info on guiding and stellar profiles is also great.
The software CCD Inspecotr he talsk about to collimate using a CCD camera is awesome. I got the latest version and played with it last night. I never collimate as I hate it, but this now makes it soooo darn easy....
