Hope I spelled it right. I just got a set of bobs knobs that I am getting ready to install on my LX200 GPS 10" and I have never done a collimation before. When I collimate the scope tonight should I use the most powerful lens? I have a 9.7mm, 20mm, and a 40mm. Does it matter which one I use to do it? Your thoughts and comments are greatly appreciated.
