NGC6946, Supernova 2017eaw just for fun
I had a hard time finding a suitable guiding star for the MGEN guider on the OAG, hence the galaxy got cornered. And sunrise was closing in so I did not reposition anymore.
The resulting image has a satellite track and also some corner (Right lower) shading from the OAG prism. This was an M48 OAG from TS which was performing very well, but for a full frame sensor it would always shade the image area. Meanwhile I switched to the M68 OAG from TS hoping for the best! Need some clear skies to test. In addition I missed the correct distance holders for the corrector/sensor distance (ordered).
