The image above was obtained using a Celestron 8" F/5 with Stellacam II at prime focus, and color filter wheel and is comprised of:
L 50 4.2 second Broadband filtered images;
R 50 4.2 second red filtered images;
G 50 8.55 second red filtered images;
B 50 2 second blue filtered images;
L 50 2 second Visible light unfiltered images...
All images dark subtracted then stacked in Registax and LRGB'd using Adobe.
Color levels were tweaked so that the result closely matched what I visually
observed using a 8" F/6 @ 48X
