Description

I imaged this almost exactly one year ago with my old set up and am back at it. The NGC 3190 Series or the Hickson 44, after Canadian astronomer Paul Hickson, is a group of gravitational bound four galaxies about 100 million light-years away in constellation Leo. The two spiral galaxies in the center of the image are edge-on NGC 3190 with its distinctive dust lanes, and S-shaped NGC 3187. The bright elliptical galaxy on the upper central portion is NGC 3193 while the spiral in the lower left portion is NGC 3185. NGC 3193 shows some detail despite being so small with my equipment and I tried to preserve as much as possible. The shape of NGC 3187 is intriguing with its distinctive S-shape. I did crop the image a bit but I like the wide field look so sort of a half in between crop.

I finished this at the end of March it has just taken me this long to process it. I am doing too many things all at once, preparing for a vacation, boy scout stuff, and my normal day job. It is a wonder I have time to do anything.
