Description

Pixinsight Process:
Image Integration: Integrate flats and dark frames.
Image Calibration: Calibrate the flats and darks into the light frames.
Star Alignment: Align light frames in LRGB to a single frame.
Blink: Allows to pick out the bad frames with lights from cars, planes, or just plain old nasty haze.
ImageIntegration: Integrate LRGB images
Dynamic Crop: Crop all images to take stacking artifacts out.
AutomaticBackgroundExtraction: Use ABE to remove some of the unwanted gradients, I use division.
NoiseXTerminator: Use NoiseXTerminator to reduce noise of the image
EZ Soft Stretch: Run basic settings on EZ Soft Stretch
PixelMath: Dreamsplease combination:
     R=iif(Ha > .15, Ha, (Ha\*.+(Oiii*.2))
     G=iif(Ha > 0.5, 1-(1-Oiii)*(1-(Ha-0.5)), Oiii *(Ha+0.5))
     B=iif(Oiii > .1, Oiii, (Ha\*.3)+(Oiii*.2))
Range Selection: Create a mask to mask the bright parts off from the background, allowing for an easy deconvolution
Deconvolution: After mask is applied, deconvolute with 5 wavelet layers, and deringing checked.
Curves Transformation: Normal S curve to boost contrast, and saturation curve to bring out some of the colors in the image.
