NGC 6888 / SH2-105
Exposure: H alpha = 70 min 1x1= Lum , RGB = 60 min 2x2
Date: June 24 - July 31, 2008. Reprocessed Oct. 17, 2010.
Comments: This is an emission nebula (hydrogen plasma in the glow mode). This image was processed via a technique (described by Rob Gendler) wherein the Halpha frame was added to both the original Red channel and the Luminance channel. Also the star color from the original LRGB frame was preserved in this final image.
