    🔭 - Biggest full moon in almost 70 years  (more…)

    On November 14th, 2016 the biggest and brightest full moon in almost 7 decades could be observed, surrounded by a beautiful halo, created by ice crystals floating through the atmosphere.

    I took the photos and videos with a Canon EOS 50D and a TheImagingSource DMK 41AU02.AS on a 500mm mirror lens from my kitchen window in Brandenburg an der Havel.

    🇩🇪 - Penumbral eclipse in Brandenburg, Germany  (more…)

    On Friday, September 16th, 2016, a penumbral eclipse of the moon occurred. For 3 hours and 59 minutes the moon moved through the penumbra of the earth.

    At the observation site, dense clouds blocked the view althrough the duration of the event. Only through a small gap in the clouds, which opened shortly after the maximum of the eclipse, a short video sequence of the eclipsed moon could be recorded for just a few seconds. At this time, a significant shade was visible at the northern edge. In the foreground a few branches of a tree obstructed the view towards the moon.

    The almost complete view of the eclipsed moon without clouds and trees in the foreground has been rendered from a moon-centered stabilized version of the movie. I used that event to test the functionality of my monochrome astronomy CCD camera equipped with a 500mm mirror lens and connected to my new notebook.

    🇩🇪 - Transit of Mercury 2016 in Brandenburg, Germany  (more…)

    In the afternoon of May 9th, 2016, Mercury crossed the solar disk for the first time since 2006. The video shows the silhouette of the small inner planet in front of the much larger sun in the background, as well as the outline of an approaching passenger plane that crosses the field of view.

    During the seven-and-a-half-hour transit, clouds kept moving through the field of view, blocking the view towards the sun. Therefore some jerky jumps of small planet Mercury are visible in the animation.
