First Light (imaging-wise) on M 32 with a Celestron C6 scope!

M 32 Andromeda Galaxy.

"First Light" with a Celestron C6 scope. Since this scope is naturally f/10, I added a focal reducer to the scope to drop it down to f/6.3, which both abbreviated the exposure times and widened the field of view to include more of the galaxy. I was concerned that my ZWO guide camera and scope might not be powerful enough to guide properly but it guided very well (and even did without the focal reducer.) Here's the data on the image above:
