NGC4157


alan4908

This galaxy doesn't often appear on SGL. It's located in Ursa Major about 56million light years from Earth and is approximately the same size as our own Milky Way. It is receding from us at 774 km/s.  From Earth you see it almost edge on, however, a little of the core detail is visible.  Three supernova explosions have been recorded in this galaxy.

Processing this galaxy was less than straightforward due to the fact that it has a low surface brightness but it is also surrounded by bright blue stars.  The LRGB image below represents 14.5 hours integration time and was taken with my Esprit 150. I've also attached an annotated version for the background galaxy fuzzy hunters.
