Quick image of M81 using just L frames. The picture was unguided using an AP1100, ONTC 10" Newt, and a QSI6120 camera. Image scale was 0.56"/px, data taken in my backyard. Just over an hour and a half of data, so not even close to a good set of time on this subject.

Looks like the core blew out on capture. Likely going to need to use some shorter frames at this speed and size of optics.

Anyhow it was fun to test.
