Description

I wanted to concentrate more on the dark nebula in the vacinity so I used the Ha data to increase the contrast in the Ha areas instead. This image is a blend of around 33% of Ha in the Lum channel for the Ha areas only. The Ha is a 6-panel mosaic and the RGB is a 2-panel mosaic. I used the new 1.5 version of Startools which seems to do a better job of stretching without bloating the brighter stars. Ha 20x300s for each panel and the RGB was 65x150s for each panel.
