My log for the Basic Level of the Open Cluster Program can be found here.
The Canary Three scope with a field of view of 112x84 arcminutes was used for all one hundred twenty-five targets for the program. Three one shot color images with a 50 second exposure were stacked for the images below. Slooh stretches the images so they are non-linear.
See the Slooh Scope Information tab at the top for information on the sites, scopes, imaging presets, and sky conditions.
The target, NGC 1807, is the small open cluster in the center of the image. The larger NGC 1817 is above it and to the left.
