Wonderful work Greg! 8)
Lots of detail, and great colors!

Question: to what color channel you apply the SII and OIII data?

Fabulous!

I wonder if it's possible to see this from the Northern Hemisphere from a place like Mauna Kea in Hawaii or Haleakela on Maui. I was at 10,000 foot level on Haleakela and was able to see down to -70 degrees in the southern hemisphere. The air was crystal clear and transparent right down to the ocean surface at the horizon. I did see one nebula that was cut in half by the horizon line, and it seemed to be rising from the deep waters of the ocean.
