21-01-2019, 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.


La Palma, december 2018.

After my trip to La Palma last year, I decided to visit La Palma again coinciding with the perihelion passage (December 12) of comet 46P/Wirtanen. At closest approach to Earth at December 16, it would probably be visible with the naked eye. Of course this period is also known for the maximum of the Geminid meteor stream. We (my parents and I) experienced exceptionally good weather (sunny, 22°C) and we were able to observe comet Wirtanen every night as well as the Geminids.

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.

After months of little to no activity a nice group of sunspots (AR2674) appeared. In poor seeiing I captured a 1/125s shot from my balcony (overlooking a big tin roof) with a William Optics 61mm, f=360mm telescope and Canon 6Dii ati ISO800.20170903_0959UT_WO61_f360mm_ISO800_1-125s_6Dii_0118_web
