Re: Collimation Proceedure
Once done, one can repeat it with much higher magnification on a focussed star in order to get a nice concentric first diffraction ring around the Airy disc. Never used a tool.

Re: Collimation Proceedure
My question is: will the possible off-axis aberrations of the eyepiece interfere with the collimation process? Also, how critical is for the collimation that the star arrives at the exact centre of the

I know that many people use DIY Duncan masks, but I bought this one because it is a precision-cut mask with a nice matte black finish, so I thought the little extra spending was going to be worth it. I glued three tiny plastic handles onto one side of the mask in order to avoid touching the corrector plate with my finger when applying the mask.
This mask is extremely lightweight and fits perfectly on my C9.25. I had the opportunity to try it out for the first time yesterday night because I found that my
Seeing was not very good with lots of intermittency. Nevertheless, I managed to collimate the scope with the mask much more easily than using the concentric rings of a defocused star. With the mask, it is very easy to find out which screws to adjust. I am sure that with better seeing, collimation with the mask will be a breeze.
I think
