I was finally able to catch some color data for this but am still lacking some blue (about 30 minutes). Total exposure time is now 250 minutes. I will return to this with more blue and some Ha.

This great galaxy is so obvious target that you usually skip it. At least I have done that for years. This fall I decided to go for it and here is the start of project. It is a 50 minutes (5 x 10 mins) exposure with luminance filter. I’m planning to take total of 6 hours of data for this galaxy, so this is only beginning.
