How do you do your polar alignment? - it seems spot on. I am wanting to improve mine.
Astrodon filters?

Thanks Greg! Yes, Rob Gendlers image is gorgeous - I used it as colour reference to get my balance right. I think with better seeing I could get even closer to Robs image though - resolution wise
.
A rough Tpoint analysis hints at a polar alignment accuracy around 30 arcsec (achieved via the polar scope). I need to do a better model to be sure though and to be able to refine it - I do see some dec drift when I look at the guide logs.
No, SBIG standard filters (Custom Scientific??)
Cheers, Marcus
