Description

This was three nights of acquisition on this target w/ a TOA 130 and ASI 6200 MM Pro camera.  Worked pretty hard to replace the huge glow of the bright blue star so it didn't dominate the upper left corner.   The RGB were all binned 2x2 and Ha was used as luminance.  Processing in PixInsight using both StarNet2 and StarXTerminator to remove stars.  I'm also using GeneralizedHyperbolicStretch more often than not to stretch nebulosity, while I'm using ArchSinhStetch to get color in the stars.  I combine the two with a screen blend in PixelMath.

Title: SH 2-185 RGB w/ Ha & SII

Description: I redid this data combining RGB w both Ha and SII data in stretched modes. I added Ha to all three RGB channels and SII only to the G band.

As always for me, NINA was used for acquisition control, PixInsight, including all three RC-Astro "XTerminators" ....
