A Totally New Mirror Lock Design for a C11 SCT
Mirror Flop, or more accurately, Mirror Drift. Over time most Telescope that achieves focus by moving their primary mirror will experience it.
I tried to solve the problem by tying the two cameras together
Flexure between two scopes can introduce unwanted image drift But after tying the two imaging trains together I saw no improvement. At that point, I felt sure my drifting issue was in the mirror system, and not in the mountings between the two scopes.
I began to research how other people had solved this fairly common astro imaging issue. Mirror locks, for the most part came in two flavors before I introduced my fairly unique design. #1 Involved locking the focusing mechanism, Meade and Celestron both offer this solution on some of their higher end scopes. and a retrofit focuser lock is available for most SCT's. It is my opinion that they do not work. They do lock the focuser, but not the mirror. #2 Involves actually ...
