2020-05-30, Crew Dragon flyby

A couple of minutes after the Internation Space Station, the Crew Dragon followed in the same orbit. Although I did not see the Crew Dragon, the camera (Canon EOS R and Sigma 135mm/F1.8 ART) recorded the flyby very low over the horizon. Individual images from this movie were stacked to show the Crew Dragon (the trail at the bottom of the image).

2019-11-11, Mercury transit.

Planned my holiday to La Palma (the Canary Islands) as to coincide with the Mercury transit. The weather was very sunny, but incredibly windy. I could only observe the start of the transit as the seeing grew worse and worse every minute. In fact the observatory on the Roque de los Muchachos issued a storm warning. I shot the transit from start to finish but only the images from the first 30 minutes were usable.

All images where shot with a Canon EOS 70D, paired with a Canon EF 300/4 @f/10 and Extender 2x-A, ISO125, 1/6400s.

Shortly after sunset bright noctilucent clouds became visible. Quickly grabbed my photogear and headed out to a spot north of the city overlooking the lake Markermeer.

2019-01-21, Lunar Eclipse.

The lunar eclipse of January 21st, 2019, took place under chilly (-8°C/17°F) circumstances. A big difference with last year’s tropical (38°C/100°F) eclipse when over 500 visitors looked at the eclipse. Despite the cold and the early morning hours some 75 observers payed a visit to public observatory Bussloo to witness another nice eclipse.

2018-07-27, Eclipse of the moon.

On the very hot (38°C/100°F) summer evening of Friday 27 July, more than 500 visitors had gathered at public observatory Bussloo transforming the observatory into a festival site. Armed with drinks, chairs, telescopes and binoculars, the darkened moon became visible for the first time at 22.05 CET, more than half an hour after the rise of the moon.

With 1h 48m, this lunar eclipse was the longest in duration of the 21th century.

After a first presentation, I looked outside through the back door; there were already more than 100 visitors waiting in line for the next presentation.

Observers on top of the hill were the first to spot the moon rising through thin clouds.
