is a popular edge on spiral galaxy, approximately 30 million light years distant, in Coma Berenices. Due to it's shape
it is also referred to as the Needle Galaxy. The central region is made up of older stars with younger blue stars in
the perophery. It is similar to our own Milky Way Galaxy, being some 100,000 light years in diameter and having prominant
central obscuring nebulosities.
Additional Comments: Image processing with CCDStack, producing an RGB. The RGB and Luminance images were combined in Photoshop
CS/3 (twice, first using soft light, then using a guassian blurred color image and the composit with the overlay option). Furthere
data stretching, high pass filtering and background smoothing (Kodac Gem) performed with Adobe Photoshop CS/3.
