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.
