M10, a Globular Cluster, - this image cropped and reduced from the original photo

M10 is located just on the West side of the summer Milky Way, in the constellation Ophiuchus, about 25 degrees above the bright reddish star Antares (in Scorpius) Like all globulars, it is old - most of the stars being around 11.4 billion years old - almost as old as the 13.8 billion year old Milky. M10 is about 14,500 light years away, half way toward the center of the M.W. It's  about 85 light years wide. In my 11" scope,  it appears a little brighter than the average globular, about 1/3rd the size of the moon. It can be spotted with binoculars, as a fuzzy, small area, just to the left and below another, similar looking G.C., which is M12. The picture here is about 2/3rds the width of the moon. The dimmest stars in this image are about 370,000 times dimmer (mag 19) that the unaided human eye can see
