Description

The Omega Nebula in HOO. This image was created by combining my exposures in Ha and OIII. I mapped the Ha to red, and OIII to Green and Blue.

I also added a powerful luminance layer on top, created with my SHO version of the image. I wasn't happy with the overall look of the SHO version, so I simply utilized some of the subtle SII details as a luminance layer for the HOO version.

I hope that made sense. lol
