NGC 457

Combination of 5, 200 second images. Modified Canon Digital Rebel DSLR camera.
5" f/5 refractor at prime focus.

NGC 457 is a large and bright open cluster surrounding the star, Phi Casseopiae. Phi appears to be a foreground object rather than belonging to the cluster. Apart from Phi, the brightest stars appear to be "B" and "A" type giants, although there is one red supergiant visible. It is commonly known as the "ET Cluster" due to its shape in a small telescope.
