Crazy work... #supermoon of Dec 5 with mineral colors. A large size mosaic with #Celestron C9.25 EdgeHD and #Nikon and #PlayerOne cameras.

On Sunday night the Waning Gibbous Moon will appear close to Jupiter. Should be a fine sight. Weather permitting. 🔭 🧪

🔭 Catching up on arXiv in a quiet moment, I enjoyed this from the abstract of Balser & Burton (arxiv.org/abs/2511.00720). The inner Milky Way is a disorganised shambles, I've always thought that. Not the most disorganized shambles I've ever seen in a bar, but that's a different matter. 🔭
Text: Taken together with decades of work on the bits and pieces of the quite disorganized shambles of the inner Galaxy, we suggest that the Milky Way belongs to the category of Flocculent spirals.

The interstellar visitor 3I/ATLAS ☄️ cruising through our Solar System is no alien spaceship and won't hit Earth. Still, the buzz around it is far from unfounded 🤩 Discover why with #ChasingStarlight: www.youtube.com/watch?v=Y… 🔭 🧪

Hubble went back to observe interstellar comet #3I/ATLAS on 30 November. At the time, the comet was about 286 million kilometres from Earth 👉 www.esa.int/ESA_Multimed... Hubble tracked the comet as it moved across the sky. That's why background stars appear as streaks of light. 🔭 🧪
The comet appears as a white dot in the middle of a large blue halo. A few stars appear as bluish streaks of light against the black background. Credit: NASA, ESA, STScI, D. Jewitt (UCLA). Image Processing: J. DePasquale (STScI)

Der Planet Merkur wird im Dezember am Morgenhimmel heller als der Saturn, aber nicht so glänzend wie der Jupiter. Sehr günstig steht er bis zum 12. Dezember. Man benötigt freie Sicht zum Südosthorizont. Beginnen sollte man mit der Beobachtung etwa 90 Minuten vor Sonnenaufgang 1/2 🔭

Da isser, der letzte Vollmond des Jahres. Damit verabschiedet sich das Thema Supermond erstmal für ein Jahr von der Bühne. 2026 werden wir wir dann ausgerechnet an Heiligabend mit einem solchen gesegnet sein... 🔭

🔭 The Bipolar Jets of KX Andromedae Image Credit & Copyright: Tim Schaeffer and the Deep Sky Collective apod.nasa.gov/apod/ap25120...
Blasting outward from variable star KX Andromedae, these stunning bipolar jets are 19 light-years long. Recently discovered, they are revealed in unprecedented detail in this deep telescopic image centered on KX And and composed from over 692 hours of combined image data. In fact, KX And is spectroscopically found to be an interacting binary star system consisting of a bright, hot B-type star with a swollen cool giant star as its co-orbiting, close companion. The stellar material from the cool giant star is likely being transferred to the hot B-type star through an accretion disk, with spectacular symmetric jets driven outward perpendicular to the disk itself. The known distance to KX And of 2,500 light-years, angular size of the jets, and estimated inclination of the accretion disk lead to the size estimate for each jet of an astonishing 19 light-years.

This is a simple target, one of my favorite visual targets. Double star system but it's actually 6 stars! Any guesses? #astronomy #astrophotography #space
Single 60s exposure of a double star system, it's actually 6 stars located in Ursa Major.

Didn't install my rotator on the scope but I think it still works. The soul nebula may get part of its head cut off during processing but it's a price I'm willing to pay. From protype 45mm f/4.5 scope and a crop sensor astrocam. #astronomy #astrophotography #space

The Cold Moon was a very cold sight here, temperature around 5°F as it crawled up Crestone Peak. The fresh snow is glistening most beautifully in the moonlight tonight. (1/2) Crestone, Colorado USA #astronomy #astrophotography

Since the Moon is currently being obnoxiously bright and inhibiting my ability to do precision photometry and deep sky imaging, I instead tried some planetary photography. Here's Saturn! It turned out a lot better than I expected. I was planning on hitting Jupiter after but it has clouded over. 🔭
A photo of Saturn. The rings are edge-on and appear dark brown. The disk of Saturn is a dim tan color.

Super full moon. 20% of best 1000 frames captured with a prototype 45mm telescope/lens and a prototype astrocam (it wasn't meant for lucky imaging at all....2fps 😱). #astronomy #astrophotography #space #moon
