–part 8 of the essay One year on Mt. Wendelstein–
Of course, when you are an astronomer, you should do astrophotography from time to time. Armed with a small tracker, I photographed a part of Scorpius with Antares, its central red bright star. Thanks to full spectrum, I could increase the amount of light for the red hydrogen region, called H-alpha, which is unfortunately quite diminished with unmodified cameras. The farther infrared parts were cut to retain this visible-light look.
