This image was quite the rabbit hole for me.  I don't think I realized just how faint the area around the dark nebula would be and that it would require a large time commitment to collect enough data to bring it out.  Also there is very little color information in the surrounding dust, but as I collected more and more data I started to see some really nice hues.  A nice band of Hydrogen Alpha streaks into the left edge of this field of view so I put a few hours on HA to bring this out a bit more. 

Beyond the challenges that the target and surrounding area presents the real difficulty was processing the data.  I must have tried a half a dozen different approaches trying all the tricks I could to bring out the color, preserve the details and minimize artifacts from having to push so hard.  It still doesn't match my mind's eye view of what I am going for, but I think for now I need to post it and sit back for a bit and give it some critical thinking and research some techniques for editing. 

In any event, I'm pleased with the image and I suspect that my next target will be nice and bright!  The pendulum usually swings the other way after I put this kind of effort into something so challenging!

C&C Welcome.
