Description

This image combines the H-alpha data with the RGB image posted here.  To do this I added 85% of the H-alpha to the red channel, and 15% of the H-alpha to the blue channel (where H-beta is).  The green channel was left alone, as there is no Hydrogen emission in those wavelengths.  Then an RGB image was created from the modified channels.  This did shift the color balance of the nebula in comparison to the straight up RGB, likely due to the increased strength of the red channel.  But the nebula is deeper and smoother.  Star colors didn't shift as much.
