–part 10 of the essay One year on Mt. Wendelstein–
One of the sad things in astronomy is that we often can’t enjoy the sunset. Certain calibration operations, the taking of sky flats and opening up the telescope, have to be undertaken during that time. Here, I simply put my camera into time lapse mode and collected photos while I was working. Normally, sunsets are more beautiful in the visible than the infrared but here I prefer the infrared look.
