Description

This is a color channel combination of my previously posted ring nebula image in Halpha and an older attempt in RGB with my NEX camera.

Color mapping:

Red = Halpha (high resolution data from ASI178, 3x drizzled)

Green = Green from RGB Bayer pattern CIS (CLS filter)

Blue = Blue from RGB Bayer pattern CIS (CLS filter)

Enjoy!
