P.S. returning to OSC and h-alpha filters. Say you have a RGGB Bayer on your camera.
With a h-alpha filter, you have just killed the signal from the GGB pixels and placed a ND filter
over the R pixels.....Sure you will still get a signal...but not very much compared to a Mono camera.

The ZWO duoband seems to work well with OSC cameras, they just seem to show a lot of Red. I was wondering if I added some subs with an SII filter then in effect I could add another channel (say Green) to my processing along with the Ha, O3 and so get more interesting colours. Would this work?
The attached image is 30 by 240 sec subs, ZWO 1600 MC Pro with ZWO Duoband filter.
