Celestron Focus Motor

Celestron Focus Motor

Although I had a Bahtinov, I found that my focus was still suffering. Doing a little research I discovered that my Schmidt Cassegrain telescope suffers from mirror shift as the temperature changes during the night. This is even more of a problem considering I’m right beside a giant body of water that heats and cools during the summer.
