Hi everyone,

Just a question about my ongoing quest for collimation perfection. I noticed that there is a lot of travel on the collimating screws for the primary mirror. I can for example wind the mirror down close to the end of the tube and collimate it there. Or I can wind the mirror away from the end of the tube as far as the screws allow and collimate it there.

Does it matter where the primary mirror is positioned along the length of the tube before collimating?

Hope that makes sense.

Shane
