Comet C/2025 R3 (PANSTARRS) imaged with a Dwarf Mini 15 sec subs for ~13 minutes. It is in Pegasus just above 75 Pegasi.

Screenshot from Stellarium showing the comet location.

Managed to capture #comet C/2025 R3 (PANSTARRS) on the eastern horizon during a narrow viewing window before sunrise. Its next pass will be in 170,000 years!

Check out my 12 panel, 71 hour mosaic of the Large Magellanic Cloud in both broadband and narrowband: app.astrobin.com/i/7thh0y

Go full screen & zoom in!

I presented it at NEAIC/NEAF for the first time yesterday and it was the main subject of both of my talks.

Big congrats!!!

An edge-on (left) and a face-on (right) galaxy combo near Ursa Major. Imaged with a Dwarf Mini for nearly 3 hrs.

Galaxy season is here!
Here’s an edge-on (NGC 4013) and face-on spiral galaxy (NGC 3938) combo. They are located near Ursa Major.

NASA's Daily Moon Guide Your interactive map for observing the Moon each day of the year, featuring detailed views from NASA's Lunar Reconnaissance Orbiter, plus special Moon events.

I was on CBC-KW this morning to chat about #Artemis II and got a lovely view of the waning gibbous Moon on my way in to work afterward. We have such a pretty satellite 😍

BTW, did you know NASA has a Daily Moon Guide with Moon-viewing tips & info? science.nasa.gov/moon/daily-m...

The ultimate selfie! Thanks Orion!

View of Mare Orientale from Orion showing areas of the near and far sides of the moon.

Great images from #NASA of impact crater Mare Orientale, now in full view. Blue line is a very rough estimate of where far and near side meet. Its position changes due to lunar libration.

Thank you. Yup, I had mentioned this in the alt text.

Screenshot: Key lunar flyby times, milestones All times Eastern, subject to change based on real-time operations 1 p.m. NASA+ coverage of lunar flyby begins 1:56 p.m. Crew passes distance from Earth record set by Apollo 13 in 1970 2:45 p.m. Lunar flyby begins 7:02 p.m. Orion closest approach to the Moon (4,070 miles) 7:07 p.m. Orion reaches maximum distance from Earth (252,760 miles) 8:35 p.m. Orion enters solar eclipse

NASA #Artemis II flyby coverage schedule; all times in Eastern. You can follow along live on NASA+ (plus.nasa.gov) or on the NASA YouTube channel (www.youtube.com/@NASA).

It should be amazing to watch!

There's a nice #Artemis II mission tracker here: artemis.cdnspace.ca

LOTS of data about its current position, crew activities, and whether or not the toilet is currently "Go"

The Moon as seen by Artems II on 4 April 2026. Mare Orientale is seen side on as the feature narrow feature on the right limb of the Moon, just past the darker blob of crater Grimaldi.

OK this is cool. The first time humans have seen the whole Mare Orientale on the far side of the Moon with their own eyes. See flic.kr/p/2s5HA2X 🧪🔭

An image of the entire Earth, with Northern Africa and the North Pole visible at the lower left. It looks like daytime but it is actually illuminated by moonlight. There’s a bright arc along the lower right where the sun is coming through from behind. There’s a bright dot on the lower right (Venus) and a glow (zodiacal light). A few stars can be seen in the dark beyond the Earth.

An image of the entire Earth, with Northern Africa and the North Pole visible at the lower left. It is dark with muted colors. There’s a very bright arc along the lower right where the sun is coming through from behind. There’s a small dot on the lower right (Venus). The background is dark with a few faint stars visible.

The whole-Earth-at-night photo from the #Artemis II mission was brighter than many expected. That was mostly due to camera settings; here’s another pic taken just before with diff settings. Digital photography is always subjective—even before processing! (HT @swapnakrishna.com @jasonc0.bsky.social)

This image was taken when the Sun was behind the Earth. Moonlight illuminates the Earth here. Notice the city lights from Portugal and Spain “above” Africa and only a slight sliver of sunlight on the right. Both aurora borealis and australis are visible. Space dust scattering sunlight (zodiacal light) is seen right where Venus is.

Let’s unpack the picture taken from NASA’s Orion after translunar injection by Reid Wiseman. See alt text.

This shot was taken with a Nikon D5 DSLR at ISO 51,200 which is why it is grainy.

It’s #Artemis II day. Aptly, on the #Moon, a cat seems to lurk.

Rubin Observatory with open dome under a night sky. Text reads "NSF-DOE Rubin Observatory has released its first world-public alerts. Here's what you need to know. El Observatorio Rubin de NSF-DOE publicó sus primeras alertas públicas a nivel mundial. Esto es lo que necesitas"

Rubin Observatory under a night sky. Text reads "What are alerts? ¿Qué son las alertas? Alerts are a "heads up" that something in the sky changed in brightness or position. Las alertas son "avisos" que indican que algo en el cielo cambió de brillo o de posición."

Rubin Observatory during an orange sunset. Text reads "Does an alert mean a new discovery? ¿Una alerta significa un nuevo descubrimiento? Not necessarily. An alert flags a change in the sky, which could be either a new discovery or a known object. No necesariamente. Una alerta señala un cambio en el cielo, que podría tratarse de un nuevo descubrimiento o de un objeto ya conocido."

Rubin Observatory under a night sky during a long exposure shot, causing the stars to streak. Text reads "Why are these first alerts such a big deal? ¿Por qué son tan importantes estas primeras alertas? Rubin is now a real-time discovery machine, enabling scientists worldwide to follow up within minutes! Rubin es ahora una máquina de descubrimientos en tiempo real, que permite a científicos de todo el mundo hacer seguimientos en cuestión de minutos."

NSF–DOE Rubin Observatory has officially started releasing world-public alerts! 🎉

Here's what you need to know about these first alerts and what's coming up for Rubin ➡️

🔭🧪☄️

Illustrated graphic with the boot-shaped Rubin Observatory atop its site on Cerro Pachón beneath a sparkling night sky and the glowing band of the Milky Way stretching from lower left to upper right. Sprinkled throughout are many "Data alert!" popups, labeled with icons that represent supernovae, asteroids, hungry black holes, and more.

A 3-by-4 grid of grayscale astronomical images zoomed in on single objects. From left to right, the columns are labeled Template, New image, and difference. From top to bottom, the rows are labeled supernova, variable star, active galactic nucleus, and solar system object.

The largest spot-the-difference effort EVER has begun!🚨

On the night of Feb 24, NSF–DOE Rubin Observatory officially released its first ~800,000 public alerts of detected changes in the night sky!🔍

A new era of discovery is here✨ 🔭🧪☄️

I’ve cropped the image and boosted the saturation, contrast, etc in iOS photos. Three Galilean moons become apparent. Callisto is not included because at 4x, it is out of the frame.

Sure. I centered Jupiter and went up to 4x. My exposure was around 2 ms and gain was around 50. You can adjust both until you get a hint of the bands in live view. Then, I go to movie mode and set it to RAW. I took a one min video and then stscked it.
You can edit the final image in the app.

Images were taken with a Seestar S50

Eyes of Clavius and Rupes Recta are revealed tonight along the terminator of the waxing gibbous (69%) moon.

Jupiter’s main bands also appear after stacking many frames taken at low exposure.

Stacking of a movie taken with a Seestar S50 shows Regulus reappearing behind the moon at around 10:05 pm EST. Luckily, the S50 was able to capture it at low exposure and gain settings.

Zoom in of Regulus reappearing behind the moon.

Regulus (alpha Leonis, magnitude 1.4), the brightest star in Leo, subtly reappears after its lunar occultation on Feb. 2, 2026. Video stacked with #seestar S50.

a close up high resolution image of the moon showing craters, mountains, and maria. Best 30% of 1474 frame 180s video taken with Orion ShortTube 80 telescope and ZWO ASI178MM camera, stacked with Autostakkert and processed with Registax and Photoshop.

I have had my Orion ShortTube 80 refractor for 30 years. I used it a lot in the 90s with a film camera. Now it is relegated to guide scope duty attached to a ZWO ASI178MM camera. Last night I let them show what they can do on the waxing gibbous moon. Not bad! Details in ALT. #astrophotography

Pardon me, it’s 700 million LY away.

Here’s the farthest galaxy, albeit faint, I’ve imaged on the Dwarf 3 - a member of Seyfert’s Sextet, almost 1 billion ly away.
