Description

An image of the bubble nebula using Quadband  for luminance and Ha, OIII, and SII for RGB. The stars are screened in from standard RGB data. The colors are "synthesized" from narrowband data using the following formulas in PixelMath: 

R: 0.2*SII + Ha*1.0
G: Ha*0.1 + OIII*0.9
B: OIII0*.85 + Ha*0.15
