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.

--------

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.
