In the previous posts, I promised you some fancy photos.
If you want to see the same thing with Hubble's eyes there it is HST - Dumbell nebula.
This is my first ever taken picture with a professional telescope (60cm one in Serbia) a few years ago. You haven't seen it in the last post, exactly for the reason of not repeating the same stuff also the one in Australia is better looking.
As you can see... nothing is automatic here, brute force solves everything - opening the dome and we even have another handle for rotating the dome - but that thing is semi-automatic, yet needs to be observed as it can go nuts.
This is CCD Camera Apogee U42 with an active cooling system. There is an effect called Dark current which affects your super fancy shots with super fancy equipment, then you need a bit more super fancy stuff - for example, dark current on this CCD is making noise on your image up until -25˚ C, and this cooling system can keep the constant temperature down to - 45˚C and it uses only air. The telescope in Ondrejov uses liquid Nitrogen and one in Australia liquid Helium.
And since you need to be out of the civilization to have minimum light pollution, there are always cool landscapes and fresh air. Also the cold nights and LOTS OF ANNOYING MOSQUITOS!
