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.

2016-05-09, Mercury transit.

Observed the Mercury transit from Public Observatory Bussloo together with volunteers and visitors. Even though the wind was strong from time to time with a less than mediocre seeing, we enjoyed the transit. After a couple of hours, clouds started to hamper observations more and more but after a dinner break, the skies cleared again and we were given a last look at the Sun and Mercury.
