I Bought this GSO Dobsonian 8" as my first telescope, and for my sanity i decided to include a collimation eyepiece (not thr laser one) with the the telescope. For my surprise ( even because a lot of people that i saw on the internet said that "this types of telescope are always collimated after the assemble until arrive at your home") the primary mirror was a little of enter, the secondary i really didn't touched, the primary it looks way better now, at least for me. Anyway, i would really appreciate if you guys could just give me your opinion about it and if it's not good, tell me what can i improve.
