Description

In 2017, I subscribed to one of Deep Sky West's (https://www.deepskywest.com/) programs, which provided data from a 135mm Rokinan lens attached to a QSI 583 WSG5 camera.  This image is a reprocessing of that data.  The system was located in New Mexico.  The data consisted of 14.7 hours of LRGB subframes plus 6.5 hours of Ha.  It was processed using Pixinsight and, to a lesser degree, Photoshop.  GraXpert AI was used to remove gradients.  Color calibration utilized SPCC.  The Ha data were not added to the RGB but were included in the super luminance (all masters), which was used to create the LRGB.  Star reduction employed Bill Branshan's method 3.
