This image was processed in the "modified" Hubble Palette as outlined by Bob Franke, where SII = Red, H-alpha = Green, OIII = Blue with the selective color tool in Photoshop being used to shift the colors to the popular and well-liked turquoise and gold motif.
This image is a collaboration with Bill Snyder. He captured all the data and we processed it. A big thanks to Bill for sharing his data and allowing us to process it and share our results with everyone.
