M11 is a bright and wonderfully rich open cluster just off the tail of Aquila. It is an easy binocular object that just gets keeps getting better in large telescopes. The cluster lies approximately 6000 light years away and contains an estimated 2900 stars in a volume of space about 20 light years across. The average distance between the stars in the cluster is about 1 light year, making this a very crowded neighborhood!
This is the first in a series of images that I will be taking to explore deepsky imaging using fairly basic equipment and techniques.
