Tsuchinshan–ATLAS comet photos album

Mario Tonin0 commentaire

I have been following this new stargazer comet since the end of September. It was kind of a gamble to know if this comet would survive passing so close to the sun and survive. But thankfully, it did survive and what a spectacle it is giving us. It might not be as bright as Neowise in 2020, but this time, I have a better camera to capture it and the pictures are just amazing. Too bad the weather was so cloudy this week… These pictures and videos were taken with my Fujifilm XT4, with the 18-55 mm or the 50-140 …

Rayons crépusculaires depuis Neuchâtel

L'ombre des géants

Prise le 4 janvier 2023, avec mon Fujifilm XT4, XF50-140mm F2.8 R LM OIS WR, à ISO 160, f2/8, 80mm et 1/250s d'exposition.

C'était une belle matinée froide ce jour là, avec deux couches de nuages, une à la surface du lac de Neuchâtel, et une autre à environ 3000m. Juste assez pour toucher la pointe de certains sommets des Préalpes. Le soleil se levait et commençait à projeter des ombres intéressantes le long du chemin. C'est un phénomène que l'on appelle communément les rayons crépusculaires.

Bien que les ombres soient en fait parfaitement parallèles les unes aux autres, la perspective donne l'impression que les ombres des pics convergent vers le soleil.

Diffraction patterns in astronomical imaging

The first image from the James Webb Space Telescope (JWST) was uncover a few days ago [1]. This is truely an incredible image, showing the galactic cluster SMACS 0723, which is slowly becoming the de-facto target for newly deployed space telescopes as it was imaged by Hubble, Planck and Chandra before JWST. This image in particular took the JWST 12.5 hours of exposure to be able to see these objects as they are so dim in the sky. The best way to see how much of an achievement this is, is to compare it to the previous picture, taken by …

NEOWISE seen from my garden

Mario Tonin0 commentaire

I know, this comet was seen 1 and a half year ago, but I didn’t had a blog then, so I have to do it now… I simply wanted to show off some of my pictures I took with a simple EOS100D and a 18-55 mm zoom lens. Nothing fancy really, but it was enough to capture the comet NEOWISE in July 2020, which was the brightest comet in a while visible in the northern hemisphere. These are a bunch of pictures, all taken with a simple EOS100D at various focal length. I stacked roughly 10-15 pictures for each final …
