This is a fine effort Roger, certainly at an .86 arcsec/pixel combination. Nice round stars. If anything, I wouldn't skimp on the colour exposures. You've got 9x5min shots for luminance which is great, but your RGB are only a couple of exposures. Try to take at least three exposures per channel to allow you to perform a median or sigma reject/clip combine. If you've only got two, then you can only average or sum combine, both of which will not cancel out noise in an effective manner. The richer your RGB data, the more you can stretch it to bring out the colours. Looking forward to seeing future developments.
