NGC 4565 - EDGE-ON SPIRAL GALAXY in COMA BERENICES

About this Object:

This might be the most famous of the non- Messier galaxies, with good reason. This edge-on spiral, with prominent dark dust lane, is a delight through just about any telescope with moderate aperture. The smaller galaxy at the bottom is NGC 4562, a 13.7 magnitude spiral, and of course many other smaller, fainter galaxies litter the field. NGC 4565 is assumed to resemble our own Milky Way galaxy if we were to view it from the outside, looking in. It rests approximately 31 million light years away. It can be found close to the unusual cluster of stars known as Mel 111 in the constellation Coma Berenices. It's one of my favorite galaxies and a wonderful springtime object.
