Messier 106 (also known as NGC 4258) is a spiral galaxy in the constellation Canes Venatici. It was discovered by Pierre Méchain in 1781. M106 is at a distance of about 22 to 25 million light-years away from Earth. It is also a Seyfert II galaxy, which means that due to x-rays and unusual emission lines detected, it is suspected that part of the galaxy is falling into a supermassive black hole in the center. The small Galaxy at the bottom is NGC4248. This image, taken on April 3-4, 2010 is a total of 4.5 hours of exposure. Seeing was not good, and I'll add some more exposure time when conditions improve.
