Description

I wanted to image this object again to see if I could improve it. I think I succeeded. It's only 4.5 hours but from the dark site. I purposely Left the background on the lighter side to try and reveal the IFN in the region. I obviously need more time on it to show more of it. Getting colorful stars are difficult in this area, I'm thinking because of the nebulosity in the region. I am happy that I captured a lot of distant background Galaxies too, if you scan the lower half of the frame.
