Hello Astromart.com,
Please help me figure out what I'm not seeing here. I have a Celestron C-11 on a CGEM mount. I had a sharply perfect picture with the scope originally, until I installed a set of Bob's knobs to replace the collimation screws. After installing the knobs I collimated the scope to the best of my knowledge using the planets and a few stars, but nothing has brought that sharp picture back. I've cleaned the collector plate a couple times too. I am in Chicago and would really appreciate any help in person or via comments.
Thank you Astromart.com
