I have a question about collimating.
Do people use a particular / favourite star when collimating / star testing?
I need to collimate my SCT as I’ve replaced the screws and was wondering if any old (or young) star will do. Are some better than others? I’ve read about magnitudes, and using stars near your intended target, but thought there may be a certain star out at the moment that, because of the way it looks in the eyepiece, can give a better result, compared to another.
Peoples thoughts on this will be most appreciated.
