Galaxies are the most remote objects: huge systems of stars, clusters and nebulae, like our own Milky Way. There are several types of galaxy: Elliptical, Spiral, Barred Spiral and Irregular.
The Galaxies are sorted on their catalog number.
All my deep sky images can also be viewed as a slideshow.

, type Sb, in Coma Berenices.<br>
RA 12 : 36.3 [h:m]; DEC +25 : 59 [deg:m]; Distance 31 million light years;<br>
Visual Brightness 9.6 [mag]; Apparent Dimension: 16 x 3 [arc min]<br>
The considerably bright, very large edge-on spiral NGC 4565 is another showpiece for amteurs, and often used in textbooks,<br>
as it is assumed that its view may resemble that of our own Milky Way.<br>
