RISSO Catalogue

31.03.2026 - 1:00 pm
The common star catalogues do not contain any brown dwarfs (failed stars) or free-floating planets, so I have created a corresponding catalogue myself. It currently contains 869 objects, 15 of which are within 20 light-years.

Space projects 2029 to 2035

15.03.2026 - 3:30 pm
From 2029 onwards, space exploration will be more interesting than it has been for a long time. ESO's super telescope will be completed, and several big spacecrafts will arrive at their destinations and will flood us with new images and findings.

Balcony Seasonstart 2026

It's actually still a bit early, but because of the very nice weather in Cologne since the beginning of March, I spontaneously started my balcony season.

Space projects 2026 to 2028

As a very space-exited person, I have looked at and listed corresponding projects that will be interesting in the next three years. The Roman Space Telescope is about to be launched, a Phobos lander is being sent on its way, several ESA probes are arriving - it won't be boring.

Lunar Crater Catalogue

16.01.2026 - 10:00 pm
Since I searched in vain for a long time for a reasonable database that contains data of craters and other surface features of our Moon, I created it myself. The basis was two text files in CSV format, which I was able to convert and expand.

New rubric Space

Two freshly created pages for my new rubric Space, one of which lists the most interesting launch vehicles, the other deals with current positions of unmanned spacecrafts, landers and rovers.

Raspberry HQ-Cam and our Moon

05.01.2026 - 11:50 pm
During the pandemic, I bought a 6-inch telescope and have hardly done anything with it so far. Two of the few videos, recorded with a Raspberry Pi HQ-Cam, are halfway presentable. Maybe that will put me in the mood for more.
