This is one of the first images taken with our TURMX remote setup at the E-EyE observatory. The target ist a classic, the globular cluster M13 in the constellation Hercules, one of the most magnificent clusters in the northern sky and also known as the Great Globular Cluster in Hercules. It consists of several hundred thousand stars in a distance of 22000 light years from earth. For a dark location you can see this cluster with the naked eye as fuzzy patch of light.
The total exposure time is only three hours and it was meant as a test of our optics. The end results turned our very nice with good resolution even in to core of the cluster and nice colors. This image is a crop of the central part of the camera frame.
