NGC 4565, the Needle Galaxy, is a relatively bright edge-on spiral galaxy in Coma Berenices. Glowing at a visual magnitude 9.6 it makes a fine target for modest size telescopes. It is thought that our own Milky Way galaxy would appear similar to the Needle Galaxy when viewed edge-on. It’s neat to see how these big beautiful spirals that appear so expansive when viewed face-on are actually relatively thin when viewed edge-on. NGC 4565 also shows a prominent dust lane common to most spiral galaxies.

NGC 4565 lies near the northern fringe of the Melotte 111 star cluster, itself a beautifully rich region in binoculars and small telescopes. This region rises in the northeast during the early evening and it high overhead after midnight.
