NGC 2808

NGC 2808 is a bright and well condensed globular cluster in Carina, that seems to be largely unknown and ignored. It deserves to be much better known and probably would be if it were accessible to northern hemisphere observers. A good object in any telescope, the cluster is visible to the maked eye, and good resolution is obtained in an 8" telescope.

Combination of 6, 1 minute images, SBIG STL-1001E CCD.
300mm f/6 newtonian telescope at prime focus.

Combination of 10, 3 minute exposures using red, green and blue filters.
SBIG ST-8XE CCD. 5" f/5 refractor at prime focus.

The strange colour pattern in the lower right corner was caused by frost on the CCD chip that slowly disappeared during the imaging.
