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.
CometAlignment: Select blinked frames, check first and last image.
ImageIntegration: Integrate comet images, Image Integration: (Combination: Median, Normalization: None), Pixel Rejection (1): (Rejection Algorithm: Sigma Clipping, Normalization: Scale + Zero Offset), Pixel rejection (2): (Sigma High: 1.5 (Play with sigma high to get the best comet rejection results))
ImageIntegration: Integrate star images, Same settings as comet images, just lower sigma high.
Automatic Background Extraction: Normal settings for ABE.
EZ Soft Stretch: Normal settings to both RGB stars and comet. (https://darkarchon.internet-box.ch:8443/)
LRGB Combination: Combine RGB Comet images, check Chrominance NR.
LRGB Combination: Combine RGB Star images, check Chrominance NR.
PixelMath: Subtract comet data from star data, (Stars-Comet), then add the comet to the star data (Stars+Comet) (this helps not clip the data.)
Curves Transformation: Normal S curve to boost contrast.
Color Saturation: Apply color curves to desired saturation.
