Well, for my msc thesis we observed neighbouring galaxy IC1613 with 5 images per 20 minutes exposure time. combining them in particular software gave us 100minutes exposition. :) Thats the biggest one I have worked with, hopefully in the future I will go for more :)

100 minutes!! That is crazy long! Even as a combined 5x 20 minute exposure is epic, hahaha
Do you have to have a really fancy camera that's specifically designed to do this type of photography? Sorry for all the questions, I just find this really interesting :)
It is crazy! :D Luckily for us we get to sit in the comfy and warm room (thank you technology) instead of spending times in a freezing cold nights. :)
I like answering thoughtful questions. :) well, usually all telescopes have mounted camera (some have two-three-four) depending what their goal is.
This 60cm telescope used this Apogee U42 and the blue thing is Peltier Cooling system it cools the CCD camera 25-40 degrees below zero.
Just to have better image and reduce the noise. :)
If this was helpful keep coming with questions or suggestions :)
only $45k MSRP! lol! well that is amazing - I know a lot about film cameras and photography cameras, but I've never investigated "Quantum Efficiency" cameras. but that makes total sense that it heats up enough to justify a cooling system of its own - that's a lot of power in there. Really cool, I'm looking forward to more of your posts!
100 freekin minutes?! whoaaa!!
