Imaging Processing

Imaging Processing Software: PixInsight

Processes utilized: Linear - calibration/integration: For each of the LUM, RED, GREEN, BLUE, Flats ImageCalibration with Master Bias, Flat ImageIntegration, Images ImageCalibration with Flat Master & Dark Master, SubFrameSelector
StarAlign all calibrated lights using best LUM image as reference, ImageIntegration of each of the LUM, RED, GREEN, and BLUE sets
Seti_Astro SASpro cosmic clarity satellite trail removal tool to remove trails on all images prior to performing integration.

Linear - Background extraction, Color correction, deconvolution, noise reduction:
LUM DynamicCrop, GraXpert, BlurXTerminator, NoiseXterminator.
RED/GREEN/BLUE DynamicCrop, GraXpert, ChannelCombine to create color image using only Red/Green/Blue, BlurXTerminator, NoiseXterminator, Image Solver script, SpectroPhotometricColorCalibration

Non-Linear: LUM: MultiscaleAdaptiveStretch, BlemishBlaster script to remove artifacts, MultiScaleLinearTransform to sharpen, GAME script to create mask, MultiScaleLinearTransform ro sharpen only the nebula.
Color:MultiscaleAdaptiveStretch, MultiScaleLinearTransform to sharpen
ImageBlend script to combine LUM and COLOR/Narrowband masters, GAME script to create mask, MultiScaleLinearTransform, CurvesTransformation to increase blue and red channels. BlurXterminator to sharpen stars and nebula slightly, DynamicCrop
