I would think you would have moisture
issues at that temp even in AZ. I
know they make coolers that fit on
some DSLR's. My choice, drive to 7,000
feet elevation. Or a CCD camera ( with
water cooling)

OK, yes I am since I’m interested in astrophotography! :-)
But more specifically, am I nuts for even trying to do astrophotography
using a DSLR (unmodified Canon SL1) during the summer in Arizona (Chandler)?
My signal to noise ratio seems to be approaching zero. If I increase the
exposure time to overcome some of the light pollution, my background noise
goes through the roof! If I keep the exposure short, then I have no signal.

a plastic bag and strapping it onto the back of the camera?
