Update to my Saturns. This goes: 2015, 2016, then annually from 2020 onwards.

🌔 Oct 19, 2026: Moon in Capricornus, about 397,500 km away and 61% lit. Through a telescope, Plato, Tycho and Clavius look crisp along the shadow line. Copernicus sits right at the edge, waiting for its sunrise. Handheld, Sony A7RV + 70-200mm f/4 + 2x TC. #Moonphase

Last night, before the clouds ruined the fun…, I got to test the new #SeestarS50Pro 🔭. Only 6 minutes on the Veil Nebula... Pretty stunning result, right?

Saturn from last night. Now that it's passed opposition, the disk shadow on the rings is just beginning to show at left, as is the ring shadow on the disk, visible as a thin line just above the rings 🔭

This is good news! I can't wait for the first science images from Roman (though they're so damn big I'm not sure how I'll peruse them). I wrote about this last month, too. badastronomy.beehiiv.com/p/nancy-grac...

One of the things that I love about research is the bringing people smart talented people together and then watching how everyone's skill sets bring us to some cool new understanding of the Solar System

Saw it... caught sight of this AM's Crew Dragon launch from Bristol Tn...

4 still photos of the beautiful #aurora display on Sat 10 Oct '26 from North #Oxfordshire, UK. The brightest part was between 7:35pm-8:45pm. I took 700+ photos for the timelapse I shared earlier so it was hard to pick 4! #SonyA7iii + Samyang 14mm lens #AuroraBorealis

Timelapse of the evening's aurora as seen from Buckfast, Devon

Treated to a lovely display tonight! Took these from the bridge over the Ythan here in Newburgh. #northernlights #aurora #nature #outdoors #scotland @davidbflower.bsky.social

Aurora spotted from North Yorkshire this evening 😀

Aurora from South West England. Can’t really make much out visually

Andromeda Galaxy (M31) again. This time I used more spacer rings on my focal reducer to get a slightly faster exposure. Better than yesterday at least, right? #astrophotography #astronomy

Fab story from Margaret Hamilton, RIP, showing why Science-Mums are brilliant scientists! When innovating at the cutting edge of technology, it's so important to bring together a wide range of lived experiences. Sad that only ~20% comp-scientists are female 👩‍🔬🧪 ℹ️: www.theguardian.com/technology/2...

i was fortunate enough to profile Margaret Hamilton in 2019. A really kind and curious person. This was my favorite story she told me:

A quick 30 minute capture of the Andromeda galaxy from my driveway tonight. This is a target I'll be going after for longer in the future!

An attempt at capturing Andromeda Galaxy (Messier 31) #astrophotography

Good morning. 6am shot of a fabulous Moon. 6.7% waning crescent with lots of Earthshine. #astronomy #astrophotography

Little time-lapse from last night. I don't know what they were doing on that field in the distance, whatever it was, it was loud!

Jupiter is about to go behind the moon. And I’m watching.

This morning's pre dawn waning crescent Moon - just 22% full! #astronomy #astrophotography

First go at processing last night's Saturn data. 8 x 3min videos, stacked in Autostakkert, derotated in Winjupos and processed in Astrosurface. 🔭

Good to be back looking at planets after a break - #Saturn is nicely placed around midnight and its rings are beginning to open out once more. #EAA #astronomy #planets #astrophotography

Last night’s Wizard Nebula from Yorkshire via our Seestar S50

A few hours last night to capture The Triangulum Galaxy, also catalogued as Messier 33 (M33). A stunning face-on spiral galaxy located approximately 2.73 to 3 million light-years from Earth. #astronomy #astrophotography

The just-past-full moon setting behind the neighbor’s house. Dwarf Mini time lapse

Last night's gorgeous #HarvestMoon, photographed from Kendal using my Seestar S50 (mosaic of two images, cropped and processed)...

Full #Moon & #astrophotography don't make a good mix, except on star clusters or emission nebulae...so here goes for the Persei double cluster (NGC884 & NGC869) and the Horse Head #nebula (IC434) in H-alpha. Images shot yesterday. Aren't those cute 😊? What do you see @kat-astro-bot.bsky.social ?

Tonight's just-barely-past-full moon casting a moondog onto some high clouds. You can see Saturn Hanging out to the lower left of the moon.

Here is tonight's moon through a telescope.

Excited to reflect, absorb, and emit light EXTRA WELL today ✨💃⚡️ #BiVisibilityDay

十日余の月 お久しぶり過ぎます。やっと晴れました。 #月 #moon #十日余の月 #天体写真 #moonphotography

Vi do il buon pomeriggio con un Saturno brutto, meglio che torno al cielo profondo 😂

Callisto and Voyager taking over this planter! #sciart

It’s international observe the Moon day. If your skies are clear, the one day past first quarter Moon will be great viewing. Images taken here last night with a little 50mm F10.8 refractor and an iPhone 15 Pro handheld #Moon #astronomy #astrophotography
