Thanks Starcrazzy. What brand/type of filter are you using? does it make a difference in light poulluted subbie area? i'm situated around very bring suburbian lights 30 minutes drive to melb city. Sometimes i wish im in the country.
I don't drift align my scope at all. no need i figured out. Think because i have a fast scope F/4 so therefore less exposure time. I just do a very accurate polar alignment matching up the octan's region from the polar scope.
