Globular clusters are my favorite objects in the night sky. Just stars. Lots of stars. This one is NGC 6760, a compact cluster containing an estimated 200.000 stars. These stars were born together and have been moving as a group through the Milky Way ever since. 280x10s subs, SeestarS50.

There she is! Comet C/2025 F2 (SWAN) 🥰🥰
It was tricky: low on the horizon, light pollution from the city, and even some thin clouds… but I got her! 🥳 (Egmond aan Zee - NL)

🔭 Last attempt to capture the Orion Nebula (M42), it slowly disappears into the evening twilight to reappear in the early morning of September.

Compilation of the partial solar eclipse, during the maximum at 12:10 about 24% of the sun was covered.
It was a bit of a challenge to take the pictures between the clouds. 😊

Exactly 19 years after the total solar #eclipse I observed in Libya, a partial solar eclipse was visible in the Netherlands today. Fortunately, it was clear around the maximum to capture an image.

Zojuist rond 8 uur boven Egmond: een groot vliegtuig begeleid door 6 straaljagers, van west naar oost. Weet iemand wat dit was? Ik zie ze niet op de radar.

Today 10 years ago, March 17 2015: my first BIG aurora!💃 And my first naked eye aurora! It was foggy and humid, but that didn’t spoil the fun. I missed STEVE because I was to focused on the north, but I didn’t know any better back then! 😄

April 8th, Arkansas USA.
I witnessed one of the most unique phenomena in Creation.
..A Total Solar Eclipse.
Gazing upwards together with a group of fellow Dutch countrymen and other eclipse chasers, it was an experienceI will treasure for a long time.
..and hopefully be able to witness again..
