| Having done this… - don’t make your camera the highest thing around. My dome was showing scratches. Eventually I got a nice photo of the inside of a juvenile bald eagle’s talon. A bird’s gonna perch where a bird’s gonna perch. Sacrifice some sky and put a better perch next to it. - the manual focus cameras seem to be temperature dependent. Maybe get something that can be auto focused or add a heater to control night time lows. - for long exposure low light work, you may find you get much better pictures in very cold weather. This relates to charge leakage in the sensor. If you decide to try keeping your sensor cold, consider condensation. Maybe have something in there that is colder. - also for long exposures, the noise in the image from leakage tends to be device pixel specific. You can make a dark view map at a given temperature and use it to denoise your images. You’ll need a shutter though, or do something clever with multiple frames as stars move around to get “darkest sample” or something |
