I am in northern hemisphere (southern US) and am new to astrophotography.
Regarding the best time of year, I know winter is typically the best (October - January).
Right now I am using a redcat 51 so 250mm and have hard time finding targets to image. Due to field of view, Galaxies are far too small for the most part and nebulae seem to be almost out of season. By the time it is actually dark, most are close to the horizon and I can only do the orion nebula so many times before I need something fresh. I have looked at telescopius but not finding many options that are suitable.
Any advice?
