Colimarea finala, de mare precizie, se face pe stea, la un grosisment macar egal cu diametrul telescopului in mm (daca nu chiar mai mare):

Colimarea pe stea o faci dupa ce ai facut o prima colimare, cu un capacel gaurit sau cu un Cheshire:

M-a amuzat concluzia autorului:

What about laser collimators? Trust me — you don’t need one. As I noted in my write-up of collimation aids, in the hands of a beginner, a laser collimator is just as likely to make things worse instead of better. Once you’ve mastered collimation with a simple collimation cap, move up to a Cheshire eyepiece if you want. And after that, if your really can’t be dissuaded, get a laser. You won’t need one, but some people find bright lights irresistible.
