I have been carrying around an old CGEM telescope mount for about 20 years. It has been moved to numerous garages and hasn't been used in at least 10 years. Dr. Frankenstein would be proud, I wiped it off, put my camera on it with old spare parts for a computer connection and tracking and decided to test it. Despite doing this on the back patio and the patio low lights and family room lights on, this came out a whole lot better than I expected. This is just 45, thirty second exposures. I think this mount deserves a full service tune up!  No darks and no flats, using a mirrorless camera with a Tameron zoom lens at about 300mm.
