Ulmer Mnster
One of my passions is infrared photography of churches in Europe, gothic churches in particular. The Ulmer Münster has the highest church tower in the world and infrared gives it a rather menacing feeling.
Infrared ash and full moon
Sometimes, strange things occur in astronomy and this was one of those nights. While observing in Texas, we realized that our instruments recorded almost no light but the sky was cloud-free. I therefore went outside to take infrared images which is when we finally realized what was going on. Seen here, the pink glow in […]
Rain in the alps
With autumn approaching, the stormy season has begun on Mt. Wendelstein where I work as an astrophysicist. Infrared is able to show the structure of the incoming rainclouds with almost no haze, making it look all the more threatening.
Lunar eclipse
While solar eclipses are a class of their own, lunar eclipses are exciting events as well. During last summer, Europe witnessed the longest lunar eclipse of the century and we observed it on Mt. Wendelstein. Right after the main event ended, I used infrared to decrease the contrast between the bright and dark regions and […]
A sea of clouds in the night
Full moon is a good time to attempt night-time infrared photography. This night, while working on Mt. Wendelstein, I was still covered in clouds with only very short moments of clear sight. While I couldn’t observe due to the high humidity, taking photos that night was rewarding enough.
An astronomer in Texas – 3
–part 3 of the essay An astronomer in Texas– The first time we could see the observatory. The road divides the image and provides a nice visual cue as to the difference of the telescopes: the left one, called HET, is an experimental, modern 10 meter class telescope that however can only rotate and not […]
An astronomer in Texas – 4
–part 4 of the essay An astronomer in Texas– Having reached the top, weather got worse quickly. Here, one can see the HET, which is located on the opposite hill, in more detail. Infrared was able to pierce the fog while visibility was much worse in the visible.
An astronomer in Texas – 8
–part 8 of the essay An astronomer in Texas– Our visibility was extremely poor in the following night, i.e. while we couldn’t detect a cloud with our sky surveillance camera, stars appeared to be much fainter than they should be. Since we wanted to do spectroscopy where every photon counts, this was a huge problem. […]
One year on Mt Wendelstein – 6
–part 6 of the essay One year on Mt. Wendelstein– While solar eclipses are a class of their own, lunar eclipses are exciting events as well. During last summer, Europe witnessed the longest lunar eclipse of the century and naturally we had to observe it. Right after the main event ended, I used infrared to […]
One year on Mt Wendelstein – 10
–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 […]
One year on Mt Wendelstein – 12
–part 12 of the essay One year on Mt. Wendelstein– With autumn approaching, the stormy season has begun. Infrared is able to show the structure of the incoming rainclouds with almost no haze, making them look all the more threatening.
An astronomer in Texas – 12
–part 12 of the essay An astronomer in Texas– A more zoomed-in photo reveals supernumaries. Rainbows are created by water drops of equal size, where light gets reflected inside the drop and, depending on the wavelength, exits the drop at a certain angle. However, if there are several similar-sized types of water drops in the […]
