Description

Trying to improve though this image brought me a lot of frustration. I think it is much better than previous M51 attempts but I still see a long way to go. This is the first time that I have used narrowband on a galaxy as well, I am interested in the "hot"regions of the galaxy. I was pleased that some detail came out.

65x320" L-Enhance filter

45x600" L-Enhance filter

Almost 12 hours integration time over two nights. Then, I added the full RGB data from a previous M51 session for "luminosity" - an additional 3 hours of RGB data.
