Two different versions of the same two original composite files. One is "normal" while the other has an inverted surface. I kinda like the inverted version myself as it seems to show more detail and also give the image a bit more of a 3D feel to it. Let me know which you prefer.
Lunt 80mm Ha, ZWO 1600mm camera. Processed using AutoStakkert 3! and ImPPG. Composited and colorized in PhotoshopCC.
