Guide camera temperature in top box enclosure #42

Open dsand opened 2 years ago

dsand commented 2 years ago

One concern with the new guide camera, which is air-cooled, is that it will heat up the top box during observing and affect image quality.

this thread will document efforts to a) determine if this is an actual problem, and b) any steps taken to mitigate it.

First step: @jhoscheidt and @griffin-h ran the guider at roughly -25 deg C in the enclosure for an afternoon, and noticed a ~10 degree temperature increase in the enclosure.

~10 degree temperature increase in the enclosure.

Just to be super clear, this is a 10°F increase.
