Too many stars in color

Time has come to colorize new refractor first light. I collected some exposures of M27 Dumbbell nebula with RGB filters, and here is the result:
M27 planetary nebula in Vulpecula
Total exposure time was 50 minutes for luminance and 30 minutes for each of RGB filters. Each single exposure was 5 minutes long. Below crop 1:1 with nebula centered (right click and open in new window to see full resolution):
M27 nebula 1:1 crop
Image pixel scale is 1.5"/px. Shot under moderate sky - about 5 mag NELM.

Clear skies!
