M31 -- The Great Galaxy in Andromeda

M31 is the most distant object that can be seen with the naked eye. It is a magnificent object to image and it graces the cover of many astronomy books and many web pages. This image was captured with a Mallincam DSm using my grab n' go ST-80 and EQ Pro. The imager was fitted with a UHC filter and sky conditions were moderate. The image consists of 11 x 30-second exposures. The dark lanes of gas and dust are clearly visible among the millions of unresolved stars that make to the glow of the galactic disk.

For reference, here is a single, processed image for comparison. Note the much higher noise level in this image.
