Description

This is M17, AKA the Swan or Omega Nebula, shot in narrowband filters. Even though it's only about 7 hours of total exposure, it took over a month to get that much time on it - the weather in Florida's been that bad! But, that's normal in the summer.

This was processed using my own not-so-secret recipe for approximating visible colors from narrowband emissions:

R = 0.5*Ha + 0.5*S2
G = 0.695*O3 + 0.094*Ha
B = 0.411*O3 + 0.1*Ha
