Description

My first test with a triband filter and a OSC. No Guiding.

I tried to separate OIII and Ha from the RGB channels with pixelmath of PI. With the response curves of the ASI294 one gets three equations (one each for R,G, and B) and can try solve the equations for the approx. OIII and Ha Signal (the third is the offset).

The the OIII signal was attributed to the blue channel, Ha to the red channel and a mix of Ha and OII to the green channel - well, that was the idea.
