I don't know what that means ? I'll upload a couple of photos in a bit

Ok so I just did a simple test. I'm using a barlowed laser collimator to collimate the primary. I collimated on a flat service perfectly and while leaving the laser on slewed the scope to about 45 deg. and the collimation just went way out. This is definitely not how it should be. I can even feel the mirror moving. The clips are almost touching so if I tighten them more I guess that would be too tight? What should I do?

Ok but should they be touching the mirror? I mean if I don't tighten the clips but tighten them just enough so they barely touch the mirror to prevent it from tilting and to prevent any slop, would that be fine?

Hello! I just checked my Newtonian's primary mirror clips and they were really tight (from factory). I loosened them a bit (fits a business card or a bit less) but I noticed when I move the mirror from facing the ground to facing the ceiling, the mirror is moving inside the cell ( towards the ground it's touching the clips, and towards the ceiling it's not) which if I'm not mistaken could lead to tilting the mirror and losing collimation when using the scope on the field? Is that normal or should I tighten the clips a bit more? From what I read, the mirror should be able to rotate inside its cell so maybe I should tighten the clips just so the mirror can still rotate but not tilt (up & down) when it moves? Appreciate any help on the subject. Cheers! -Anthony
