Having fun with a GoPro Hero3 camera. Before any night time observing occurs, the telescope and instrument require set up, and calibration images need to be taken. We arrive about an hour before sunset (which was roughly 6:15pm local time during the week I was there) to start setup. First we fill the instrument’s dewar with liquid nitrogen to keep the instrument cold. Then we do calibration images. This time-lapse shows the hour of set up and calibration we did on one of our observing nights.
I couldn’t capture a time-lapse of the whole evening because the GoPro doesn’t work well at night. GoPro’s are designed for day time use. Ah wells.
