Binning calibration frames?

[DaveS]

I had been imaging at Bin 1 with the ODK rig, but that has a sampling rate of 0.61"/px which my seeing won't support. The 'scope and mount will easily support this resolution though (Move the whole lot to Chile?).

Therefore it would make sense to run at Bin 2 and 1.22"/px

However the daytime temp is making getting calibration frames at -25c problematic, as I currently use T-shirt flats in daylight. I have a flip cap with flat field panel on order but it's being delayed.

Options therefore are 1) Bin 2x2 after calibration and stacking, 2) Bin master calibration frames 2x2. I am using a CCD camera which I think is better binned in hardware, but binning in software wouldn't be disastrous.

Your thoughts?

If its just the flats, then there's no harm trying to software bin if you've already got some. If they don't work then you could try some evening flats when it's a bit cooler.
