Description

A secondary target I shot during an unusual week of clear dark skies. I really had to dig into the data on this and kept putting it off since there are flashier targets. What makes it difficult is there's almost zero Oiii and Sii is actually stronger (?). Made me think I put the wrong filter orders in the wheel!

More data would pull the dust out better, but for the limited time I wanted to devote to this target... I kind of like this object describe as a hole in some rocks

Finally ended up on this technique to make the most of the data:
  1. Combined H, S, and O averaged integration into a pseudo Luminance type image
  2. Used LRGB combined, but with SHO and the combo averaged L channel
