Imaging Processing
Imaging Processing Software: PixInsight
Processes utilized: Linear - calibration/integration:
For each of the LUM, RED, GREEN, and BLUE lights: 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
Linear - Background extraction, Color correction, deconvolution, noise reduction:
LUM DynamicCrop, GraXpert, BlurXTerminator, NoiseXterminator
RED/GREEN/BLUE DynamicCrop, GraXpert, ChannelCombination to create color image using only Red/Green/Blue, ImageSolve, SpectroPhotometricColorCalibration, BlurXTerminator, NoiseXterminator
Non-Linear:
LUM: MultiscaleAdaptiveStretch
COLOR: MultiscaleAdaptiveStretch
ImageBlend of Luminance and color images, HistogramTransformation to darken background.
