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, >16m galaxies are visible too, in spite of the heavy light pollution.

M 92, NGC 6341, Mel 168 [globular cluster in Her] M. 92. Very fine example of a globular cluster. Very gradually condensed to a bright centre. 6.5m ø14′ [wiki] [simbad] 750mm

PGC 59938 [galaxy in Her] 15.04m ø1′ [simbad] [photo-planner]
