Messier 92

I chose an unlikely location to image M92, I thought since it was in the zenith, I imaged it from the city. So I used my equipment, the N 150/750, Baader MPCC Mark III, Canon 1100D mod, HEQ5 with no naked eye Milky Way. I acquired 11×90 sec ISO 800 frames. Then began the hunting.

To my surprise, many faint, >16^m galaxies are visible too, in spite of the heavy light pollution.
