A splendid cold walk to Fiddlers Gill to see the fab but rusting Victorian #Braidwood Telescope! Once part of the now long-gone Lanark Observatory, its optics are safe at the Lanark Museum. Sadly I see no hope in restoring this beauty tho, that's been long-abandoned in this field ☹️ #histsci 🔭🏴󠁧󠁢󠁳󠁣󠁴󠁿
Catherine (tall, long blonde hair) standing in a wintery field by a large old rusting telescope. The golden setting sun is illuminating the trees in the distance.

3 images of the Moon tonight taken with #CFF160 🔭, #TeleVue 2.5x Powermate, #Touptek 585M camera. Best 25%(Southern uplands) or 5% (Sinus Iridum and Copernicus) stacked from 2500/5000 frame video in AstroSurface, and further processed in PixInsight. #astrophotography
Southern uplands of the Moon. The prominent crater Tycho with its bright ray system is in the upper centre of the picture. Clavius is down and slightly right, and the elongated crater Schiller is on the terminator to the left. Sinus Iridum showing wrinkle ridges. Copernicus crater with its terraced walls and ejecta pattern. Lots of small craters visible around it.

Two images of Jupiter from last night. #CFF160 🔭 with #TeleVue 2.5x PowerMate and #ASI585MC camera. Europa and Io visible in left image from single video (best 10% stacked), and right image is stacked from 12 x 60s videos in WinJupos. #astrophotography
Single 60s video of Jupiter, processed to show moons Europa (left of picture) and Io (right, closer to Jupiter). North is up, and Equatorial belts very prominent, with other belts clearly seen. 12 x 60s videos of Jupiter derotated to bring out some additional detail. More detail visible in N and S equatorial belts, along with white and red ovals.

Absolutely fascinating talk to @astronomyedinburgh.bsky.social on Kuiper Belts around other stars by Tim Pearce of Warwick University, and how you can use images of them to infer existence of exoplanets. Available to watch on YouTube: youtu.be/z0JPizgxe2k #astronomy

How have I only just discovered google maps for space? If you, like me, did not know about this little piece of internet treasure, you must check it out! You can fly over moons and planets - and it's all real data 🤗 🔭🧪

My first go at processing a SeeStar mosaic using Siril and the DSA script. Needed more data than the 84mins used.

The Geminids are already firing and the peak should be tonight (14 Dec), clouds permitting. The Moon is kindly hiding too. These are a few from Friday night. Capturing 200+ in each of our cameras overnight (we have 17 in the Society). 🔭
B&W image of Geminid meteors showing as different intensity and length streaks of light plus star trails around the pole in the background and lights from distant cars along the horizon. Over 200 captured Radiant map of the Geminids showing 245 blue streaks captured by one camera on 2025-12-12 coming from one point, the radiant of the meteor shower

A brief clearing in the skies last night allowed me to get quick snaps of the Moon and Jupiter. CFF160 🔭, #TeleVue 2.5x Powermate, #Touptek 585 mono camera for the Moon and #ZWO ASI585 colour for Jupiter. #astrophotography
Waning Moon from 6 December. Prominent craters on the limb are (from top to bottom): Langrenus, Vendelinus, Petavius, Furnerius. Petavius has a broad, deep rille that runs from the central mountain group to the inner wall. Jupiter and Galilean moon Io. The North Equatorial Belt shows small red spots, and blue streaks, while multiple belts are visible in the southern hemisphere. North is up.

🔊Big in #Biggar!

If you're in the #Lanarkshire area, the Biggar Science Festival's Christmas lecture in the Corn Exchange, will be featuring yours truly. We'll be discussing the 4 questions that I'm most often asked! 🏴󠁧󠁢󠁳󠁣󠁴󠁿🔭

⏰: 11th Dec @ 19:30
🎟️: biggarce.yapsody.com/event/index/...
Catherine (tall and blonde) in the setting Sun with large telescopes behind her (this is the rooftop of the Paranal observatory in Chile). There are 4 questions listed: Will humans ever live on the moon? What are the chances of Earth being hit by a killer asteroid Are we alone in the Universe? What will happen at the end of time?

A fascinating, clear and understandable talk by Dame Jocelyn Bell Burnell explaining how technological developments (for example CMOS cameras, leading to much shorter exposure times) have led to the realisation that many more objects in the universe than we realised are variable.

A big shout out to the P7 class of Stockbridge Primary who took these utterly awesome photos last night on their residential visit to the Lagganlia outdoor learning centre in the 🏴󠁧󠁢󠁳󠁣󠁴󠁿 Highlands. Lagganlia is part of the Scottish Youth Telescope Network and I'm so proud of these kids! 🥳 🔭 #SYTN
An almost full silvery moon in awesome detail, pockmarked with craters. The swirling galaxy that is Andromeda with two little dwarf satellite galaxies, one above and one below it. The pacman nebula - looks like a pink piranha on a star studded sky

2025’s Geminids will be the best meteor shower of the year
With a waning Moon and a denser-than-ever debris trail, 2025’s Geminids might be the year’s best meteor shower, and 2026’s could be amazing.

Note, you don't need to be Scottish to celebrate! How about a nice bowl of porridge for breakfast or a wee dram of whiskey at the end of your day? 🥃

A time-lapse of a typical night observing with our remote telescope in Spain: ASERO. On an average night we observe 6 variable stars, a couple of comets and a chosen deep sky object - all selected by our members. 🔭☄️
Sometimes we do live observing, always fun!

Me and my good pal Andrew from @astronomyedinburgh.bsky.social gatecrashed a local #supermoon gathering last night with his Dobsonian🔭. Minds were blown as we looked at the lunar mare and craters through patchy holes in the cloud cover. Pop-up sidewalk astronomy at its best - loved it!
People pointing up at the stars. In the centre a reasonably large telescope looks up towards the moon. A gathering of people lit up by the supermoon moonlight in patchy cloud People huddled around a telescope, the moon in the sky. The astronomers red light gives the scene an eerie glow.
