Description

Another summer highlight. I love the texture of this thing. The red channel got the Ha beautifully, but a little dose of narrowband OIII helped perk up the G and B.

Revision F: Reprocessing project; this version goes much lighter on the OIII data, and as a result there is less emphasis on some of the edges. But it is a little softer and I think more appealing to the eye. Ideally I will go back and capture Ha data on this and make a narrowband + RGB overlay composite.
