NGC 3239 galaxy with numerous other galaxies.  32 inch Schulman telescope with STX camera on Mt. Lemmon, AZ.  Data capture and reduction by Adam Block, University of Arizona. LLRGB processing by JDS using CCDStack and Photoshop CS5.  Note the apparent tight cluster of 3 stars below and to the right of the very bright star superimposed upon the main galaxy; the object in that triad closest to the main star is actually in NGC 3239, unlike the other stars, and is a supernova known as SN2012A.
