Hi,
I do use Pempro but it has let me down with inconsistent results so has phd2 and alignmaster. This is an eq6 with a belt drive with very low backlash.
so I fixed a cctv lens to my guide cam, a lodestar, used a 25mm piece of pipe to fix it to the polar scope and it has been the best thing ever.
I've been imaging for about 2 years so have drift alignmed with various methods including the darv method, but the polar scope method has by far been the most consistent and easiest method for me and I do 40min guided subs with virtually no drift. very minor over 30mins.
using a sensitive cam on the polar scope means I can easily see the asterism from light pollution central.
I did test it on a friends mount after he aligned with alignmaster and it was noticeably off even after 3 iterations of alignmaster.
just my experience.
Cheers
Alistair
