Hi fellow astrophotographers,
I try to gather much info about the best ressources you have found - books, dedicated websites and youtube videos - about « collimation » of your instruments.
Please post a brief title (Collimation of Ritchey Chretien / Newton etc…
and your links.
Thanks for your help !
