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. This image was taken over two nights, May 3 and 4, 2014. It totals 5 hours of exposure. The composition is a little lopsided but I wanted to include the bright star at the upper left. The small galaxy at the extreme right is NGC 4248.
