Description

The title refers to a thread on Cloudy Nights, and the fact that Alnitak is the curse of ASI1600MM sensors. As seen here. 

I combined the Ha data with each channel as follows:
Red = 0.5 x Ha + 0.5 x Red
Green = 0.1 x Ha + 0.9 x Green
Blue = 0.05 x Ha + 0.95 x Blue

Description: I notice the awful diffraction pattern around the bright stars was most prominent in the green layer, so I created a synthetic green layer from the red and blue layers and used that instead of the original green layer. I also used Russell Croman's BlurXTerminator for deconvolution on the luminance layer.
