Overheating camera sensor with astrophotography?
"special astrophotography cameras" ... well 'yes' but they often start out with a $20 million pricetag
However - many keen astro-togs can bolt a small camera - even a smart-fone onto a decent $2000 telescope with azimuth-guidance geometry and as the telescope follows a target group of stars, the camera keeps clicking away, but building upon a single target ~ thus revealing the beautiful depth of detail and colours that are "up there". Once the images are stacked (after removing any cloudy ones) the remaining images provide a wonderful result
Hope this helps

"This is not like commercial CCD camera that you can buy.
It's optimized for very low light it has 4x 9 megapixel CCD
chips in it that record a field of view about the size of the full
moon they're in a vacuum can they're cooled to liquid nitro-
gen temperatures"

Light is free… capturing it is not!
