OBJECT DESCRIPTION AND IMAGE SESSION

M93 is one of the latest deep sky objects found by Charles Messier personally. It was discovered and catalogued on March 20, 1781. The cluster is rather small but bright and gathers approximately 80 members covering an area of 20 to 25 light years across. The brightest stars of M93 are blue giants of type B9 and its age has been estimated as roughly 100 million years.

A great object to image from a light polluted area as my home backyard. In this case I was testing the Starizona Correctors which seems to work very well with Schmidt Cassegrain Telescopes. The image was cropped only for aesthetical reasons.
