I bought my GSO dob 2 weeks ago and never thought of collimation as particularly scary. I think the thing that scares people the most, is that they don't want to touch the collimation for fear they may never get it back to how it was in the first place. After I had, had a look through my scope the first thing I did was play with the collimation
. I figure if I adjust it so it's way off then at least I'll know I'm doing the right thing if I can get it roughly back in line.
Incidently, I still don't know if my scope is collimated as well as it could be, the star tests look nothing like those i've seen on the internet. My previous scope was an 80mm refractor so obviously even if it's not collimated my new 12" will show much more. Any advice on an object I could use to test my scope on? eg a double star.
Cheers
Daniel
