HF radio interrupted this morning after an X5 solar flare hits Earths ionosphere. #WebSDRtwente

ISS solar transit this morning 🙂 Castricum (NL) #SeestarS50

Last year I captured some incredible video of the aurora during the Gannon Solar Storm. Thanks to @raymondkphoto.bsky.social it’s now beautifully edited and brought to life! 🤩 Watch the full video on Youtube: youtu.be/NGR6kUQebkY

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.

At the peak it was raining, but I still managed to catch some weak aurora :-D Egmond aan Zee (NL) 0:47 CEST #aurora #poollicht

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) #SeestarS50

🔭 Last attempt to capture the Orion Nebula (M42), it slowly disappears into the evening twilight to reappear in the early morning of September. #Astrophotography #seestar #M42 @kat-astro-bot.bsky.social

De zon vandaag, met de Seestar S50 :) Van zonnevlekgroep AR14048 is niet veel meer over helaas.

Wat hebben we genoten van de #zonsverduistering en de heerlijke lunch bij Het Lage Noorden! 🥰#sterrenkijken #friesland

De gedeeltelijke zonsverduistering geprojecteerd op de grond via een vergiet (tip van @govertschilling.nl). De hap uit de zon is mooi zichtbaar!

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. 😊 🔭 #seestar #eclips #solareclips #sun #moon

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.

Composite of today’s partial solar eclipse 🌞🌑 9 images taken with the Seestar S50, timed to capture the full progression of the eclipse. #zonsverduistering #SolarEclipse #Eclipse2025 #SeestarS50

Eclipse day!!! #zonsverduistering

Bitte was das am eben am Himmel? Fast moving bright object (Like ISS) + spiral lights from west to east in the night sky some minutes ago @dlr-next.bsky.social @yousitonmyspot.bsky.social @aswogeosphere.bsky.social @nikzimmer87.bsky.social @manueloberhuber.bsky.social @jureatanackov.bsky.social

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.

She's a bit weak, but she's there!! 💃💃 #poollicht #aurora

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! 😄 #poollicht #Egmond

De totale maansverduistering vanochtend, zoals deels zichtbaar vanuit Nederland. Begin intreden bijschaduw (1), begin intreden kernschaduw (2) en net voor de Maan onder ging (3). @leonoor.bsky.social @johanklos.bsky.social @govertschilling.nl @suerob7.bsky.social @roelvanderheijden.bsky.social

Lunar eclipse 🥰🥰 #SeestarS50

SpaceX out, ESA in.

FINALLY 💃💜🥹 Hello #Aurora, nice to meet you here at 46°N #Koralpe #Austria #NorthernLights @aswogeosphere.bsky.social @nikzimmer87.bsky.social @chrisoutofspace.bsky.social @manueloberhuber.bsky.social @jureatanackov.bsky.social

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..

Messier 51 tonight :-) Seestar S50, 437 10s subs :-) www.astrobin.com/skbzjx/

Another clear night, another deepsky target: Markarian's Chain 🥰 Seestar S30, 1048 subs, mosaic. 🔭

I braved the cold to take some more videos of the planets. Here's Jupiter from my backyard in Purmerend, NL. 🔭 #astrophotography

Last night clear skies! Time to play with the Seestar S30 telescope 🥰 Messier 44, 752 subs (mosaic) (Sorry, I made a mistake, so I posted it again)

This one never gets old… The Horsehead Nebula in Orion. Automated sequence running with the ZWO ASIair Pro + 📷 ASI2600MM Pro + 🔭 Takahashi ε-180ED @ 500 mm f/2.8 + 🔴 Baader Planetarium Hα f/3 Ultra-Highspeed filter (3.5nm).

Nog even zonder leerlingen sterrenkijken #SeestarS50 #Sterrenkijken #Astrophotography #Astronomy #Alnitak #HorseHeadNebula #Paardenkopnevel

Had another go at #Jupiter last night with my trusty 18cm maksutov in my backyard in Purmerend, the Netherlands. With the Great Red Spot, too. #astrophotography 🔭 Stil have lots of data to go through, so more to come :)

Maan door wat lichte sluierbewolking, 22% verlicht, vanavond zondag 2 februari vanuit Friesland. #astrofotografie #maan #sterrenkijken #astronomie #sterrenkunde

Last night we finally had clear skies again 😍 The Seestar telescope was happily at work, and here’s the result: NGC2237 (mosaic), M44 (mosaic) and M61.

Last night's Jupiter #Astrophotography #Jupiter

An impressive cluster of active regions has rotated into view across the NE solar limb. While large & fairly rich in sunspots, these are mostly simple active regions: 3978 - alpha, 3976 - beta, 3977 - beta-gamma. Only 3977 has a more complex configuration, favourable for flares.

On the way home: Yay, clear skies 🥳Got home and set up the telescope: clouds 😭 Welcome to the Netherlands.

Ik heb een starter pack gemaakt met Nederlandssprekende astronomie- en aurora- kenners en liefhebbers. Niet iedereen post alleen in het Nederlands: een aantal woont hier wel al heel lang en spreekt het vrijwel perfect. go.bsky.app/GrRBHxQ

Heute habe ich ein ganz besonderes Geschenk erhalten: Ein Freund hat meine Timelapse vom Kometen #TsuchinshanATLAS - aufgenommen am 21.10.2024 auf der #Koralpe - bearbeitet und ich finde das Ergebnis großartig!

Horsehead Nebula last night :-) 1064 10sec subs, Seestar S50.

It's windy but finally a clear night!⭐️ The Seestar S50 is currently capturing a mosaic of the Orion Nebula + Running Man Nebula 🥰

Jabbah 🙂 #SeestarS50
