Operating camera in low temperature conditions

I've been using my E-PL1 and E-M10 in sub zero temperatures for prolonged periods of time. A lot of those times they were on a telescope, which means the sensor was directly exposed to the environment. The cameras are still working perfectly.

Just remember to not bring the camera directly into a warm room. You need to put it in a bag. And don't open it for a few hours after coming back. Let it slowly warm up to room temperature. Otherwise you will have water condensing, which is not a killer on the outside of the camera, but if it happens somewhere inside it, bad things may happen.

Yes, that's what I was thinking too. I think my garage will do nicely As far as bags are concerned, are camera bags alright?

Also, since you are here, I'm testing out different settings for taking wide angle pictures of Orion and other constellations under light pollution (between 14mm and 20mm). I'm doing RAW+JPEG so I need a quick comparison of different settings I'm using (shutter speed, aperture and ISO). Would you set contrast and saturation to default (0) and sharpening to its lowest (-2) (in natural picture mode) to get the best possible OOC Jpegs to compare the results at different settings quickly or would you use a different combination of settings for contrast, saturation and sharpness? I want the optimal settings to preserve star colors, and to achieve clear easily detectable differences between stars of different colors and classes and to detect the dimmest possible stars above the noise floor and background sky while keeping ISO noise to a minimum.
