Get a laser collimator for 10 or 12" scopes - necessary!
Every time you move a scope of this size you have an opportunity for the mirrors to become slightly mis-aligned.
True the mirrors are mass produced in China, but the bang for buck is immense! Compare GSO price with hand figured mirror in 12" size.
Outside the beginners budget!?
Colour - ethereal green every time, but it's gonna be a hell of a brighter green in a 12" Dob!
All the best
