Total Lunar Eclipse 2015

The September 28th total lunar eclipse was very impressive, as it turned out to be a very dark one, and for once, it happened in a perfectly clear sky.

This is a collage I created from six separate exposures showing the extent of Earth’s umbra. The exposure times and ISO settings are given to show the huge difference in brightness between the partly and fully eclipsed moon. The collage was inspired by this visualisation: https://svs.gsfc.nasa.gov/cgi-bin/details.cgi?aid=4340. The images were shot through a 127mm f/8 apochromatic refractor.

Here is a combination of two timelapse sequences:

Backpacking Astrophotography

My backpack was way too heavy, but somehow I managed to trek from Schattenlagant to the Cavalljoch. The night was the darkest night I ever experienced. M13 was clearly visible with indirect vision with the unaided eye. Read More
