Photo description / processing

SH2-157 The Crab's Claw and a lot around it. It was shot on a leftover basis after the main summer targets. An extremely tricky object to process in the context of harmonious palettes. None of the SHO versions have pleased me so far. The current one is H+S-O-O, and even then, I can't say I'm completely happy with it. I definitely plan to gather more signal this summer—maybe a new version, and a colorful one, will come out.
