Description

Raw frames courtesy of Deep Sky West Remote Observatory in New Mexico, USA. (deepskywest.com) Data obtained with FSQ 106EDXiii / QSI683wsg / Lodestar / Paramount MyT.

21 hrs total integration (16x900s R, 16x900s G, 16x900s B, and 18x1800s H-alpha). The palette is RGB with H-alpha serving as Luminance.

Processing in PixInsight.

-----------

CFH (HOS) shows subtle details a lot better for this nebula, IMHO, than the conventional SHO palette.

------------

Revision shifts the color axis toward the way it is probably supposed to be done. Use the entire nebula to get the white reference. This tones down the excessive H-alpha and produces even greater color contrast between the O-III and S-II rich regions.
