IC 2082


Combination of 8, 3 minute exposures, SBIG ST9XE CCD camera.
300mm f/6 newtonian telescope at prime focus.

IC 2082 is one of the brighter members of a rich cluster of faint galaxies in Dorado, about 1.5 degrees north of alpha doradus. In the image above, it is the bright galaxy near the bottom of the image. At magnitude 13.8, it is readily visible in an 8" telescope under dark skies.

There are over 50 PGC, ESO and anonymous galaxies in the above image plus two other IC galaxies. The IC galaxies are the 14th magnitude IC 2079 (the brighter of a pair of galaxies near the right-centre edge) and the slightly brighter IC 2081 near the top of the image. These are also visible in an 8" telescope under dark skies. This cluster would be an interesting challenge for a large telescope as many of the galaxies are below 16th magnitude. The galaxies are indicated on the image below and their details listed in the table.
