M57 - Ring Nebula


M57 is the expanding gas shell from a supernova explosion tens of thousands of years ago. This image was taken at GMARS in September 2008 through the 14-inch LX200R with an SBIG ST4000 and an AO-8 unit. Captured in Equinox Image and processed entirely on a Macintosh in Nebulosity 2.0, Photoshop CS3 and Leopard Preview. Note the tiny galaxy, IC1296, to the upper right of the Ring Nebula; it is at least 50,000 times farther away than its celestial companion.
