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.

2 hrs total integration (8x300s R, 8x300s G, 8x300s B). The palette is RGB. Optimally weighted Luminance was derived from the three color channels and applied. Star erosion was applied to diminish the overwhelming field stars.

Processing in PixInsight.

This is the initial cut on a data set that also includes S,H, and O channels. This RGB image is superb. The deep red carbon star near the center of the image, just above the Crescent Nebula, really comes through as an anomalous kind of star.
