This is my latest version of Messier 95, the previous version is from five years ago. M95 or NGC 3351 is a barred spiral galaxy approximately 38 million light-years away and 70,000 ly across making it about half the size of our own Milky Way. The spiral arms are tightly bound to the central core and contain many young blue stars as evidenced by the blue regions in the rings. Another interesting feature is the bright nuclear ring that surrounds the core. It is not clear to me why some galaxies have this but quite a few do. Also interesting to me is the dark red/brown dust lane across the inner core.
This image is orders of magnitude better than my previous attempts which were captured with less than half the focal length as this version. Also my processing is much improved, however, given the relative size of this galaxy, I believe the focal length was the biggest factor.
