digital camera ISO setting

Of course that one's

There are quite a few cooled CCD options in the low thousands aimed at keen amateur astronomers some of them even with autoguider software to keep the telescope tracking stars exactly and the odd more exotic tip-tilt corrector. It is in the ball park of what amateurs will pay for a decent camera. There is some crossover with scientific CCDs as well for less demanding work the amateur grade gear will do the job OK.

All of them with active cooling need to be tethered to a computer, monitor and power supply. Though battery operation is possible. The tradeoff is weight of battery against hours of operation.

To some extent it must trade speed versus noise, or S/N. It may trade resolution as well.

Check again, f-stop in the lens impacts depth of field due to strictly optical issues.

It reads the sensor before the optimum charge builds up necessary for a perfectly sharp picture
