I finally made the jump to a mono CCD which I picked up second hand here on the forums. Of course, I got a huge bump in quality and decrease in required exposure time .. very happy!
In playing around with the HST colour palette I got a nice looking image but then for kicks added a 50% blended layer of RGB data from the QHY12 OSC CCD and ended up with this result that draws out the narrowband ranges nicely, but leans back towards the visual red of the emission nebula and natural blue/orange stars.
Ha + OIII = 30 x 60s subs with hyperstar / QHY9m mono
SII = 28 x 180s subs with hyperstar / QHY9m mono
RGB = 40 x 180s subs with hyperstar / QHY12 colour
