For the moment, I have set up 2 refractors side-by-side each with its own ASiair Plus and each running separate CCDs ( a ASI1600MM Pro with NB filters on a SharpStar 94EDPH and a ASI533MC with an Optalong L-enhance filter) on a SkyRover 72ED. The mount and guiding are controlled with one ASiair (the1600MM) and both CCDs have their own EAF. I have disabled dithering for now, to see what the price may be in added noise. To partially offset, I plan to run the 2 coolers at -20C rather than my normal -10.
So I can run both CCDs simultaneously. I have already identified one drawback to that - the 2 CCDs have different fields of view. The 1600 is wide enough to get M8 and M20 in frame while the 533 points at a spot in between the 2. Bugger!
The bureau suggests the weather may clear in a week or so but by then the moon will be about 2/3 and growing. Still, it should be OK for testing this setup.
More to follow.
