Messier 45 ... The Pleiades Star Cluster
I took this picture Sunday evening in between many passing clouds. There were a total of 41 usable images (1hr 22mn worth) but many of those were on the fringe of usability and more than 50 (nearly 2 hours worth) that had to be trashed due to clouds. I used the wide filed Canon USM Telephoto 70-200mm zoom lens, zoomed all the way in at 200mm. I plan to photograph this target soon with the lens zoomed all the way out (70mm) to show a super wide field of view, but that will have to wait until these clouds move out along with the waxing moon.

This beautiful cluster, Messier 45, 'The Pleiades' or Seven Sisters, is the finest open cluster in the sky of very young stars located in the sky in the constellation of Taurus the Bull. The stars are only 115 million years old and are only about 425 light-years away. This naked eye object is best viewed during the autumn and winter months. To the naked eye, it looks like a fuzzy patch of stars high in the NE sky after a few hours of rising.
