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.

14.5 hrs (13x1800s H, 16x600s R, 16x600s G, 16x600s B). Palette is standard RGB with Ha excess, and implied Hb, added to each channel.



The addition of Ha brings out some fainter nebular regions, but obscures the magnificent O-III blue.

--------

Rev B -- Instead of adding Ha to the image in the usual manner, I tried just using Ha as the Lum channel. This does two things: (A) it drastically reduces the field stars without the associated star-reduction fogging, and (B) it preserves the blue Oxygen strength in the image.
