NGC 457, the Owl or ET Cluster (Sept. 2020)

NGC 457 is one of my favorite open clusters.  Through a telescope, it is stunning, partly because of the contrast between the brighter stars and the dimmer diamonds.  This image is 19x300" with the Atik 460EXC through the 203mm f/4.95 Synta-ONTC Newtonian and an Astronomik CLS filter.
