Omega Centauri
While in Namibia, I imaged the largest globular cluster or galaxy remnant we have, the ω Centauri. I used a rather dark 300 mm photo lens, and my Canon 1100D mod on the HEQ5. I have taken 36×90 sec, ISO 1600 at f/7.1, according to the EXIF. I may still have some unprocessed raws hiding in some folders on the external hard drives :)

NGC 6791
I also captured an open cluster, 12x90sec, ISO 800.

It is not particularly interesting for visual/photographic viewing, I chose it because it is on my local zenith – and accessible in spite of the heavy light pollution. It is however a cluster that fell onto the sensor of Kepler during its first mission, and it is a very very old cluster. At 13000 light years, it is also very very far away for a visible open cluster.

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.
