Images captured with TheSkyX
Session orchestrated by CCD-Commander
Calibration and processing of the RGB and Ha and OIII in PixInsight as follows:
RGB: SPCC, BlurX, NoiseX, Gradient, Curves, HistogramTransform
Ha and OIII: BlurX, NoiseX, StarX, Curves and HT and LHE
Ha / OIII combine with their respective stars done via the Foraxx script in PI

Photoshop processing:
Split channels: Added the Starless Ha to Red at 100% and Blue at 20% using Lighten Blend mode. Added the starless OIII to Green and Blue using Lighten at 50% then Selective Colour and Curves adjustments.
The HOO image from PI was also used. I layered the RGB over that using Lighten and some subsequent adjustment layers.
Small tweaks and small noise reduction then Save-for-Web
