There are few objects in the sky as dynamic and as exciting photographically as M82. This nearly edge on spiral has prominent dust lanes, and a rich red spray of hydrogen nebulosity coming out of the core region. Once thought that the core of this object was exploding, we now know from spectroscopic radial velocity measures that it is more of a slow movement outward. I recomend that at least the 1200 size be seen, the detail is worth the extra time of the download!
