Notes: Image acquisition with TSXPro using MaxPilote automation software.

All Processing completed using PixInsight and the following steps:

- Blink/WBPP/Pixinsight Gradient Correction/BlurXT/NoiseXT/StarXT/GHS/RGB Color combine - I didn't like the Foraxx method with this data so instead I used Channel Combination, SHO normalization, SNCR,Saturation
Created separate Lum layer using Ha channel/BlurXT/StarXT/NoiseXT/GHS/Mask/LHE/MLT/Add Stars back. I didn't like the synthetic RGB stars with this data, so used Ha stars
LRGB combination/Saturation/Histogram Transformation/Crop/Annotate

Calibrated w/30 Darks, 100 Bias, 10 Flats of each filter using a flat panel. CCD temperature was -20C. Image was taken from my backyard Observatory.
