Innovant - L'actualité des innovations · « On l’a vue avant la NASA » : des astronomes amateurs révèlent cette planète géante gazeuse, une découverte qui ridiculise les pros du spatial - InnovantLa découverte d'exoplanètes est une aventure fascinante qui ne cesse de captiver l'imagination des scientifiques et du grand public. Parmi les récentes découvertes, l'exoplanète TOI-4465 b, située à environ 400 années-lumière de notre planète, se démarque par ses caractéristiques hors du commun. Son orbite elliptique et sa masse impressionnante, six fois celle de Jupiter, suscitent
Lunchtime daystar imaging.
I still have no idea how to use CCDCiel or Siril, I wish someone could teach me how, I think I got it working once and then it refused to work again. I hate using default OS camera software with autoexposure.
Anyway, there's some cute starspots up there right now.
I recently updated the HYG star database and the AT-HYG (HYG + Tycho-2 and Gaia) star database to include updated proper names for 34 stars that the IAU has approved since May, 2024. If you're using these databases (or are interested in checking them out), get the updated files from Codeberg. https://codeberg.org/astronexus. #Astronomy #AmateurAstronomy

For astrophotography,
Are skies clear tonight?

Many years ago during a particularly warm night, which had exceptionally viewing I was able to capture a short video of Saturn through my Meade LX90. Please keep in mind this was filmed with my phone through the eyepiece all the while I was being eaten by mosquitoes. #saturn #astronomy #meade #telescope #amateurastronomy #feedingmosquitoes
M51 (Whirlpool) Galaxy
You see here two galaxies coliding and a lot of new stars forming.
The galaxy is ~24 million lightyears away…
Clearing out some more editing backlog. Here's the Tulip Nebula from the Spring 2024 Bootleg Astronomy Star Party. More details on Telescopius and Astrobin. Thanks for looking and Clear Skies!

@AstroHawk C’mon #AmateurAstronomy Empiricists, we have to get that figure up, a lot.
If you only count cases where I’ve seen light from ‘em directly in an eyeball (with at most a couple of lenses or mirrors along the way, no computers or CCDs), then I’m up to 25: the Big 8, two dwarf planets (Pluto and Ceres), another asteroid (Vesta), and 14 satellites (1 for Earth, 4 for Jupiter, 6 for Saturn, 2 for Uranus, and 1 for Neptune).
Is there a #amateurastronomy bubble here. I think i joined the club. (Gearwise not skillwise. 
)
Continued thread
It's hard to find pictures on the internet that capture the level of detail that you can see visually on a target like Jupiter, since so many are either from close-up missions, or from ultra-powerful observatories like Hubble, or are the result of capturing the best of hundreds of images and "stacking" them into a clean final image. The top image (the one with all the labels of Jupiter's cloud bands) on this web page is pretty close to what I was seeing, except in general, what I was seeing was sharper. The time lapse image a little further down is also close. #Astronomy #AmateurAstronomy https://britastro.org/2017/jupiter-and-the-amateur-astronomer

A very lovely #AmateurAstronomy night even with city lights. The sky was unusually steady for an hour or so and the views of Jupiter and Mars were among the best I’ve ever seen with this scope (a 12.5”(32 cm) Dobsonian reflector). I also said a likely goodbye for the season to M42, the Orion Nebula, and also got very nice views of open clusters M48 (Hydra), M35 (Gemini), and M37 (Auriga) #Astronomy #AstronomyInPDX
Another animation of #Jupiter with three of its Galilean Moons. Note the little dark spot on the planet: that's the shadow of Europa, which is moving to the left. It still amazes me what can be observed with an 8" telescope. #Astrodon #astrophotography #amateurastronomy
And another account cleanup is under way.
I've maintained a star database, the HYG database of stars (a mashup of the data from the Hipparcos, Yale Bright Star, and Gliese catalogs) since the early 2000s.
In the early 2010s I moved a copy of the DB to Github, where it's been actively maintained for almost 15 years. So it's been around for a while. It's gotten "starred" on Github over 700 times and been forked 145 times.
And I've finally got tired of various Github shenanigans recently, mostly having to do with generative "AI" training, but also for various other flavors of enshittification I could have scarcely imagined in 2010.
I am moving this repository to Codeberg tonight.
For the foreseeable future, the Github repo will be available as a read-only resource, but I do not expect to maintain the Github account indefinitely.
#M41 and #M42 taken with a 80/480 scope and an EOS450D DSLR camera. I'm still waiting for an adapter to use the flat field corrector and the camera still uses the original IR-cut filter, so there's still room for improvement. #astrodon #astrophotography #amateurastronomy
Pictures of our neighbor planets #Mars and #Venus, as well as #PlanetaryNebula NGC2392 taken with an 8" Newtonian and a ZWO ASI462MM camera. Color images are composites taken separately with corresponding filters. They're not perfect, but I'm pretty happy with the results. #astrophotography #Astrodon #amateurastronomy
