I am helping a friend who owns a CPC1100 with HD Pro wedge and wants to get started in Deep Sky Imaging. He also has f/6.3 focal reducer, Lodestar X2 and ordered ASI1600-cooled color camera. Since he is a beginner, I suggested he start guiding with a finderscope converted to guide scope because it's easier than OAG. Please do not make any suggestions to use OAG because that will come later when he wants to advance to next level.
The eyepiece of Celestron finderscope can be removed and it appears to be 2" or M48 threads because I can screw in a 2" eyepiece barrel into the rear part of the finderscope. I believe I found necessary adapters to accommodate 1.25" guide cameras like Lodestar. Here is what I found so far and I am asking whether they will work:
The first link will screw into 2" or M48 at rear of finderscope. The second link will screw into the first link and Lodestar can be inserted inside the 1.25" eyepiece holder.
