Description

Two nights from my backyard on the Shrimp with my 12" Goto Dobsonian, my ASi2400MC camera and L-Ultimate filter.   I cropped my capture to about half the sensor frame because the Shrimp is fairly small, just to save processing time and data.

I did pretty standard RGB processing, but added a bit of Oiii enhancement by creating a separate Oiii layer with PixelMath with Oiii = (G*2 + B/3) - 0.15 * R     
This does a pretty good job eliminating the unwanted Ha absorption by the G and B sensors.
