Description

Three nights on the head of the Seagull Nebula w/ my CDK 14 and ASI 6200MMPro and Astronomic Deep Sky Filters.  Formed a Synthetic Luminance out of two copies of Ha and one of SII with PI Image Integration.  The integration weights were by PSF Signal Weight and approximately 0.7 for Ha and 1.0 for SII.  Typical SHO pallette stretched w/ a bit of STF/HT, then GHS.  The SynLum was sharpened in two steps w/ BXT (one w/ stars one w/o) and imprinted onto SHO w/ LRGB combination, but that image was mixed into the original with PixelMath using a 1:1 combination.
