Nice work Phil.

What are you narrow band filter mappings? Are they "SHO" (hubble style) or HOS?
SHO = R: SI G: Ha B: OIII
HOS = R: Ha G: OIII B: SII
HOS gives a more natural view, but depends on the object being framed.
What is absent from your information is exposure lengths per channel... would you mind telling us (including the subs). I'm expecting something in the order of a few hours at least.
