Open Star Cluster NGC 1513 in Perseus

An 10 minute exposure with an ST-9E CCD camera thru Kopernik's 20-inch F/8.1 Ritchey Chretien Cassegrain telescope, working at F/4. The field of view is about 16x16 arc minutes, with South at the top.

Quote from: The Deep Sky Field Guide to Uranometria 2000:

"Nine arc minutes in diameter; 50 stars; brightest = magnitude 11.19; Moderately rich in stars; small brightness range; slight central concentration; detached."

Data from the 'Tycho Catalog' shows that the bright star at the bottom of the image is a B-9 blue giant that is at a distance of 1,125 light years. However, this star is probably a foreground object and not a part of the cluster.
