NGC 4565, also known as the Needle Galaxy, is the finest and brightest example of an edge-on spiral galaxy in the sky. It shines at magnitude +9.5 and therefore is bright enough to be seen with small telescopes. The galaxy is located in the constellation of Coma Berenices. Since positioned at the eastern edge of the sprawling naked eye Coma Star Cluster (Mel 111), it's easy to find.

NGC 4565 was discovered by William Herschel on April 6, 1785. It's number 38 in the Caldwell catalogue and is best seen from northern locations during the months of March, April and May. This spiral is physically large and similar in size to the Andromeda Galaxy (M31).
