I wonder what the timber is. It's probably not the boss of yew.
A wooden ceiling boss from Carlisle Cathedral. Dating to around 1400, the boss can be viewed in the Cathedral’s treasury. 📸 My own. #Woodensday #CarlisleCathedral

Happy Birth Certificate Day to my wife.
Legend has it that the ward Sister liked a sherry, and was a bit hazy on the date. So, like the Queen - sorry, King - she has an official birthday and an actual birthday. So we celebrate both :) 🍹🍹

When I started this Christmas card project in 2022 never did I think it would raise £50,000 for @womensaidni.bsky.social in just a couple of years but with your support that’s what we’ve done to this point. Looking forward to seeing what we add to that this year.

I'm sorry but Elon has finally done something wonderful here. He has made a new word, and it's a beaut:
'𝗔𝗿𝗱𝘂𝗿𝗲' noun, portmanteau of '𝗮𝗿𝗱𝗼𝘂𝗿' (meaning passion) and '𝗼𝗿𝗱𝘂𝗿𝗲' (meaning shit).
Usage: when Hatie Plopkins offers to blow you.

Had to stop on the way home this arvo, when the rain got a bit too enthusiastic. Had the opportunity to listen to a few thumbnail-sized hailstones whack the car roof too :-/

Another session with the #Seestar S50 last night. Getting a feel for what it can/can't do, but there's much to learn—including accessing/using the RAW files; maybe this weekend. Also need to test it in a dark sky, not suburban.
Here's 3x Orion neb w/ different exposures, and the Helix nebula. 1/n 🔭

Haven't had many clear skies lately, but tonight obliged so I pointed a camera at comet C/2025 R2 (SWAN). 16 6-second exposures, ISO-1600, f2.8.
In the photo, SWAN is comparable in brightness to M22, but through 9x63B, it was more like M23 appears in the photo. 🔭

Aaannd... the young photographer at The Daily Planet is toting a brand-new Praktica L plus Domiplan lens, with toy flashgun. I reckon Weegee would be turning in his grave (but still getting the shot). #BelieveInFilm

I don't recall being hassled by wee fruit flies in Scotland. Tonight I've resorted to a lid and a decoy glass, but I don't think they're entirely fooled.
Where do they hang out, before the wine is poured?
