Description

Originally, I started this project a quick one to capture M18.   I ended up liking the framing and used this an opportunity to experiment with some HA/LRGB blends.   This version is my current favorite.   I left the core a bit hot so you could see the "swan" in M17 which is such a dominant feature when you look visually.

In the process of working thru my final blends, I was struck by the detail that came out in some of my starless working files.  I went ahead and then created a starless version  as a revision.    Not sure which I like better...  Take a look.
