Description

"Mouth" of the cave nebula. Emission nebula in Cygnus, with the "cave" caused by dust which obscures both the emission nebula and the background stars.

I used the Ha as the luminance image, with the RGB providing colour.

Reprocessing: was struggling to get a good red colour. Merged Ha with R - didn't help. Finally used the colour saturation adjustment in the LRGB combine tool in PI (normally I do saturation adjustment in curves later). This finally brought out the red!
