Description

Later this month, this will become a Hubble Palette version of the “The Wall” in Cygnus. Since the moon is nearly full, I can only get away with shooting Ha and SII images now. For kicks (and because I’m impatient), I combined the Ha and SII data, minus any OIII to see what would happen. While the resulting color palette is…well…unorthodox, I thought some of you might like this anyway. For better or worse, I submit to you this experimental image. Your comments, positive or otherwise, are welcome.

For those interested, the red channel is 100% Ha, green is a 50/50 blend of Ha and SII, and blue is 100% SII.
