NGC 457 NGC 457

NGC 457 is an open cluster located in Cassiopeia, often called the Owl cluster, or a more recently the E.T. cluster with the two brightest stars forming eyes. I tend to see it more as an Owl. The cluster contains some 150 members and has an estimated age of around 21 million years. Less than idea weather for imaging, with a thin cirrus clouds, but a good bright target for commissioning the RC 10 scope and the ZWO 2600 mono camera.
