The Dark Shark Nebula. 8 hours (over 2 nights) to capture the beast from the deep! Processed to reveal interstellar gas and dust in the northern constellation Cepheus, appearing as a shark-shaped silhouette against a star field. #astronomy #astrophotography @stormhour.com @photohour.bsky.social

My favourite area of the Moon, the Mare Imbrium region, bordered by the Appenine mountains to the east. Zooming in, Hadley Rille can be seen snaking around the foot of the mountains while, to the north, the Alpine Valley looks like a chisel-cut through the mountains.

Another close-up from the 25th. The seeing was a bit wobbly, but pleased to have captured Hadley Rille, landing site of Apollo 15, snaking around the foothills of the Apennine mountains C11 with x1.58 barlow and Uranus-M camera. Astronomik 642nm filter 🔭

Wow. The rille is to the right of center. RIlles are grooves in the surface left behind by flowing lava, in this case billions of years ago.

It's a little known fact that the #Moon sometimes likes to rest in a tree during the day, before continuing its journey across the sky after night falls. 😄 #Astronomy

•Circumscribed Halo and 22º Halo. •Corona with multiple color bands. Both optical phenomena were seen this morning over northern Arizona. #azwx #weather #AtmosphericOptics

A 'through the clouds' capture this evening's Moon - Have a good week ahead folks! #astronomy #astrophotography @stormhour.com @photohour.bsky.social

Thor's Hammer 🔨

First image from last night. I almost quit after seeing the low 7 fps of the high-res mono camera. You can see some artifacts in this image showing Archimedes in lower center, but it turned out OK. The Apollo 17 landing site is by the small rille at very top center. Details in ALT. #astrophotography

A handy bit of libration gave a nice view of Mare Australe last night

The Lunar Alps at sunrise - captured last night

A little, flapping, UFO of some kind from last night's imaging

A few straight out of the camera. Same scale/field of view for comparison. Moon and Jupiter with its moons, upper left to lower right: Europa, Ganymede, and Callisto. Io actually in front of Jupiter. #Fujifilm X-T4 through a Celestron 8” SCT

Great post:

A timelapse of the 36% lit #Moon close to Jupiter passing through the frame of my camera on the night of 22 April 2026. The tiny dots either side of Jupiter are its moons Ganymede and Callisto. Some passing cloud adds to the scene 😀 #Astronomy #Astrophotography #Space

A bit of last night's Moon. The prominent crater near the left, above the terminator is Maurolycus, its peaks and floor nicely lit here.

Two more Moon images from last night. #CFF160 🔭, #TeleVue 2.5x powermate, #Touptek 585M camera. Best 25% frames from 1000 frame video, stacked and sharpened in AstroSurface. #astrophotography

Love this shot of Saturn near the solstice. The rings are casting those shadows on the cloud tops.

SPACE NARWHAL CONFIRMED.

This is a close-up of M51, the iconic Whirlpool Galaxy interacting with its companion galaxy NGC 5195. I tested a new Spectral Pro filter from Leviathan Optical on this target and was pleased with the result. More details in my gallery: app.astrobin.com/i/dzmjiz #astrophotography

A few photos from observing the Pleiades covered by the Moon. Unfortunately, some of them were taken through clouds. Canon 500D + Tair 3S #astrophotography #Ukraine #Kropyvnytskyi #Canon500D

Success with Comet C/2025 R3 PanSTARRS this morning! Clouds will prevent future attempts. It reaches perihelion Sunday, swings around the Sun and becomes a southern hemisphere object. This is a composite of a tracked image of the sky and untracked foreground image. Details in ALT. #astrophotography

DESI finished its originally planned survey last night!! ..and will keep going :) I made a cake to celebrate. 🌌🔭 @desisurvey.bsky.social

Tricky capture of comet C/2025 R3 (PanSTARRS) this morning. By the time it had cleared the trees to the east the sky was pretty bright. Nice to have caught it at least. #Astronomy #Astrophotography

Seen so much amazing #Artemis art here! Had to do a quick doodle 🌕🌎 #SciArt 🔭

Ye Freaking' GADS I could write 2,000 words about this if you woke me out of a dead sleep. Hmph. Maybe I will. Dang.

Comet C/2025 R3 (PanSTARRS) Ashurst Lake, near Flagstaff, AZ Blend of two images: (1) comet and stars; (2) foreground and lake. Was hoping for some reflections in the water but it was too breezy. Nikon D850, 35mm, ƒ/1.8, ISO 100, 2x240 seconds. #astrophotography #comet

#M101 #Galaxy Total or 3 nights (2 nights with L-Pro filter and 1 with L-Ultimate for H-alpha layer. About 13 hours total on this target)🔭 There’s still quite a lot of hot pixel noise in the L-Ultimate master after WBPP, I’m trying to figure out the cause, but overall the result is quite satisfying.

The Tadpoles Nebula. This cosmic cloud that looks like tadpoles swimming through the cosmos... Zoom in!! It is actually an area of massive star birth, the tadpoles shaped by intense stellar winds. It took 12,000 years for this light to hit my yard in Victoria, BC.

Mark diaries: solar #eclipse 4 months from today! UK #scicomm chums, if you're planning an event for the 🌞🌚🌍 partial alignment, @gostargazing.bsky.social are offering v reasonable rates for solar-spec bulk-buys: 200 for £25. Deadline for orders is end of May! ℹ️: gostargazing.co.uk/solar-glasse...

The Leo Triplet is a small group of galaxies bound together by gravity in the constellation Leo. It lies approximately 35 million light-years from Earth and consists of three prominent spiral galaxies: Messier 65, Messier 66 and NGC 3628. Captured over two nights in March 2026. #Astrophotography

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. #astronomy #astrophotography #space

TONIGHT (Saturday 11th April) at 7:30pm I am delighted to be visiting Cotswolds AS again, to give my Astrophotography Highlights talk. They meet at Deer Park Archers archery club, Shurdington Road Cheltenham. Non-members are welcome - £2 entry fee

With a change in the weather, possibly my last image of the Sun for a while. This is the area around active regions 4008 and 4009 and shows some nice bright faculae near to the limb. Taken with an Esprit 4" refractor, Herschel wedge and Player One Uranus-M camera from my garden

Crescent Moon and Crescent Earth from Artemis II. 🔭 🧪 #astrophotography #ArtemisII

This might be one of my favorites from Artemis II. A cinematic alignment of the Moon and Earth, each cradled within the warmth of sunbeams. Taken from behind the Moon on April 6th. flic.kr/p/2s6BABn

Drew it. Experiments with colored pencil (& sharpie for some black). 🔭🐡

finished this right as the astronauts went behind the Moon 🥹 #SciArt

1 hour on Rosetta Nebula just now as I awaited my next galaxy to rise above the trees. That’ll be tomorrow’s image. This cluster of bright, young, hot stars is excavating a cavity in this enormous cloud of hydrogen gas and dust. An annoying satellite crossed into the FoV. Captured on SeestarS50.

二十日余の月 寝坊しました！明るい！ #月 #moon #二十日余の月 #天体写真 #moonphotography

Comet! C/2025 R3 (panSTARRS) Maybe my last clear morning for a while. Had to be creative to find a small window of visibility with trees and my house in the way but 10 mins x 15 secs exposures & there it is, cropped/processed. #astronomy #astrophotography @stormhour.com @photohour.bsky.social

The 62.7% waning gibbous at 4 AM (UTC+7) on Thursday.

Can you imagine the cataclysmic impact that formed the Orientale Crater on the lunar far side? look how big it is. It punched a hole in the lunar surface, lava welled upwards (dark patch) and it made concentric rings of mountains. Ooooft. Source: images.nasa.gov/details/art0... #ArtemisII

Whoa 🤯 The Moon, in full eclipse, with the #Artemis II Orion spacecraft. Part of the Moon and spacecraft are lit by Earthshine, and both Saturn and Mars are visible to the lower right. Incredible. Details: images.nasa.gov/details/art0...

Earthset from Artemis II. I am overcome.
