The deployment of the immense prominence of May 23 for 135 minutes! 😎 Watch it in full screen and compare to Earth to scale! Takahashi FSQ-106ED, Coronado SM90 DS, Player One Saturn-M YT link: youtube.com/watch?v=xJR2k4…

This is also applicable to partial solar eclipses: the part of the Moon not covering the solar disk is invisible and undetectable. So, any dark disk outside the Sun is just a Photoshop drawing!

Here's a transit of the ISS I took in 2015 As depicted here, the ISS is visible over the solar disk but not over the "sky background" (which is not the corona but only atmospheric and instrumental glow) That's PHYSICALLY IMPOSSIBLE! 🤔

Today's huge and fast prominence, only 15 minutes between each of those images! 😎 The Earth at scale on the left 😲

Today's partial eclipse from Paris in Halpha and calcium K 😎

Vivid and colorful northern lights on Jan 27 from Skibotn, Norway 🤩 Coming soon: the breathtaking show of Feb 1st, thanks to a huge coronal hole 😊 Sigma fp-mod & 14mm 1.8 Art

@Space_Vagabond yes! thanks for the warning!

I did not want to miss Saturday's occultation of Saturn, it was the last one until 2031! So I traveled to Tarragona, Spain 😊 The star besides Saturn is 85 Aquarius (mag 6.7) C8 Edge HD & ASI178MC

@curiosityonx you have used my photo while removing the copyright. It's illegal. It's robbery.

A fascinating view of Saturn and the Moon captured in 2025. 📸 Immanuele la ba

@NellieBly666 no, but I will have a look...

@ThierryLegault Are you on blue sky? I really miss seeing your outstanding images.

@ThierryLegault What did you use as a source for the next Saturn occultation? I know I have once found a website that showed a list of future occultations along with maps but right now I'm struggling to find anything for after 2027

@SyzygyCoffee there were a dozen in 2024, but the next series starts in 2031

@ThierryLegault How rare are these? Because I took this just a few weeks ago 👀 and yeah, we saw it come out from behind the Moon, and it was breathtaking. All a coincidence, too!

I got Bronze medal at the 24/25 German Photo Book Prize! 🤩 <<This award recognizes the exemplary photographic quality of the award-winning work >> Many thanks to dpunkt Verlag 🤗 Or course, the original French 4th edition is also available in all bookstores! 😉

My very last shot of Tsuchinshan-ATLAS from Gran Canaria last night...before going back to France! 🤗 Sigma fp mod & 20mm 1.4 Art DG DN, 15s @f/2

My last shot of Tsuchinshan-ATLAS on Thursday from Maspalomas dunes (Gran Canaria), with a view of the lighthouse 😊 It's amazing to see how fast the comet moved away from Earth, just three days after my Monday shot in La Palma! 😲

Tsuchishan-ATLAS tonight with its tail and anti-tail over the huge Magic telescopes at La Palma observatory, Canary islands 😊 Sigma fp & 20mm 1.4 DG DN

Giant X4.5-class flare in AR3825 today! 😍 Just 15 minutes before this image, the flare ejected matter visible on the left at very high speed: 400 km/s! The Earth at scale in the corner 🙂

Magnificent prominences today including huge loops! 😎 The Earth at scale on top 😮

@frizbee12 c'est déjà quasiment la résolution maxi

The Moon, Saturn...and the ISS! 😎 After the May 31 occultation from Argentina, I wanted something more challenging! 😁 I decided to install my telescope in Spain, in a precise place near the Almendra dam in Castilla&Leon to catch the ISS just 30 min after the occultation 😜
