Nordic landscapes and northern lights – 13
It was a truly magical night, as we crossed the aurora crown and it danced right above us. It was so freezingly cold that only two of us remained, but it was worth it!
Nordic landscapes and northern lights – 14
The last night of northern lights had a particularly eerie feeling to it, as the aurora was quite faint but very active. The infrared sky emission made itself known again, as well. As before, there is a remarkable difference in water reflections between full spectrum and infrared.

Here, full spectrum truly shows what firework we could see if our eyes had infrared capabilities as well. The sky has a purple taint due to the infrared sky emissions and the horizon again shifts colours due to visible light absorption.
Nordic landscapes and northern lights – 16
On the last full day, Norway said goodbye with a particularly scenic sun setting above the coastal mountains. I couldn’t be happier with what we have seen and experienced on that voyage.

I couldn’t be happier with what we have seen and experienced on that voyage and, if times change and travel becomes more free again, I would love to return.
Historic Fraunhofer refractor of USM
The old observatory of the Universitätssternwarte München in Bogenhausen and its Fraunhofer refractor used to be one of the most modern of its time. However, more than a century has passed and it is now under monument protection. It provides a very nice background for our new office building!
Infrared Isar
The first color infrared photo I ever took with an ancient Sony F717 in night mode, showing boats docked at the Isar river close to the city of Landshut.
Roadtrip in Texas
After a week-long observing run in Texas, having collected data in sufficient amounts to keep ourselves busy until next year, we enjoyed the scenic route back to the airport, the road leading up into the magnificient mountain pass below the clouds.
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.
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.

–part 5 of the essay An astronomer in Texas– The weather cleared (more or less) nicely for the first night of the observing run. However, several thunderstorms were still visible on the horizon, which led to a sight I never thought I could see: lightning arcs below the milky way. Taken in full spectrum, lightning […]
