ISS Transit in front of the sun

On Sunday, May 1st, I was lucky to have the ISS transit the sun only a few kilometers away. Weather played with my plans as well. So i packed my solar scope and drove to a place right in the center of the transit line.
The transit itself is a very brief event. This particular one lasted for less than 2 seconds. So everything hat to be well set up before the clock reached 08:24:22 CEST.

This image is a combination of 15 individual images captured in 1.02 seconds. The solar surface was further enhanced by a stack of 880 frames adjacent to the transit itself.

High-Res Moon

Yesterday evening, during our astronomy club chat, I had my scope active to observe the moon. Fortunately, there have been quite stable air conditions. So I could record several craters, mostly located near the terminator for best shadows in the crater valleys 🙂

Moon meets Venus

In the morning hours of October 14th, before dawn started to illuminate the sky, Moon and Venus were quite close next to each other. With a distance of 4 degrees and only 10% of the lunar surface illuminated, it was a beautiful sight!
