Telescope remote controlled (itelescope.net)
Mosaic of 2 frames, cropped
Processing Flow: PI, each channel of each frame separately: ImageRegistration with StarAlignment, ImageIntegration, DynamicCrop (12 pixels on each side), DBE, then both frames merged to a preliminary mosaic frame with StarAlignment (Working Mode: Register/Union-Mosaic, Frame adaptation), StarAlignment of the separate frames with the preliminary mosaic (working mode: Register/Match Images, Frame adaptation), GradientMergeMosaic
PI, mosaic: ChannelCombination (color channels to RGB), DynamicCrop (RGB and L-channel), again ImageRegistration with StarAlignment (RGB with L-Channel) and DBE.
PS: Combination of L-channel with RGB to LRGB, curves and levels
