The Open Clusters of Cassiopeia
Orion 8" f/4 Astrograph

 
 Here
            are a few shots from several weekends ago which Ive just processed
            of some open clusters in Cassiopeia. The 8 inch astrograph excels
            on such objects and reveals a wide range of star colors and brightness.
            All images from the observatory up in Happy Jack.
