The trouble I had with collimation was I always turned the bottom screws in the same direction moving the primary mirror closer to the secondary, this made it hard for me to focus on stars properly. I then decided to lower my primary all the way to the bottom and start again.(be careful not to unscrew too far, I screwed one all the way out and it was abugger to get back in) once I had done that and re-collimated i got a lot clearer view on everything I looked at. I haven't touched my secondary mirror at all (too scared) as like others have mentioned I don't really understand the steps involved. Pinching?? sanding?? may as well be double dutch to me.
A few experienced members John B and George have had a look through my scope and they tell me that the mirror is fine and that the views I get are ok, so I'm happy with that. But I would really love to know what to do with the secondary for my own peace of mind.
