A 20:5:5:10 minute LRGB CCD exposure taken with an STL-1301E camera thru Kopernik's 20 inch F/8.1 telescope. Image taken at 3:15 UT on April 12, 2005. The field of view is 12x12 arc minutes with North at the top.

Supernova 2005ay:

Follow this Link to a NASA Web site on supernovas. It has a very nice animation and a description of what these objects are.

Spiral Galaxy NGC 3938:

NGC 3938 is a face-on Spiral Galaxy in the Constellation of Ursa Major. It has a small bright, diffuse nucleus in a bright inner lens. There are two bright, filamentary, knotty arms that begin near the center and unwind for about half a revolution, before branching. Thin dust lanes are present throughout the inner arm region, the inner disk, and the inside of the principal luminous arms.

Based on the published red shift, (and a Hubble Constant of 62 Km/sec per Mpc) a rough distance estimate for NGC 3938 and SN 2005ay is 43 million light years, with a galaxy diameter of about 67,000 light years.
