The #SuperbOwl Nebula! 🏈 #astronomy #astrophotography

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. #astronomy #astrophotography #occultation #moon

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

Two stars, two galaxies, two clusters: Canopus - 2nd brightest star (and the home star of Arrakis in Dune) Achernar - 9th brightest star Large and Small Magellanic Clouds - dwarf irregular galaxies NGC 2516 - open cluster 47 Tucanae - globular cluster #astronomy #astrophotography #arrakis #dune

The luminous red #nova (LRN) AT2025abao in the Andromeda #galaxy was discovered by Koichi Itagaki on 10/17/25. Here is M31 on 6/25 vs 11/14 this year imaged with a #Dwarf3 telescope. The lower right inset shows the bright nova after the merger of two stars. #astronomy #astrophotography

The brightest crater on the moon stands out during the waxing gibbous phase (~89%). The relatively young Aristarchus crater was formed 450 million years ago. #moon #astronomy #astrophotography #seestar

Timelapse of Two Travelers — Lemmon orbits with a majestic and dynamic tail spanning a few degrees. SWAN silently sails with almost no tail yet proudly marks its presence with a green glowing nucleus, a signature of diatomic carbon. #comet #astronomy #astrophotography #space

An H-alpha image of the #Sun on Aug. 30. Left: result from raw images aligned and stacked. Right: color rendering of the left image in Photoshop to bring out the prominences. On the disk are spicules or “fur”, filaments and plage (white regions near sunspots). #astronomy #astrophotography

Neptune and Saturn imaged with the #Dwarf3 telescope on August 12. Two of Saturn’s larger moons,Titan and Iapetus, were discernible. #astronomy #astrophotography

2 Pallas, the 3rd largest asteroid in the solar system, is now in the constellation Delphinus. It will be in opposition and at its brightest on 8/10. Currently, it is at magnitude 9.4. The brightest star in each image is Saulocin. #astronomy #astrophotography #dwarf3 #asteroid #minorplanet

Seyfert’s Sextet, found between Hercules and Serpens, consists of 5 galaxies and a long tail of stars of one of them. NGC 6027d is not gravitationally related and is actually 955 million LY away! The other 5 are only 190 million LY away. Such old photons! #dwarf3 #astronomy #astrophotography

The Crab Nebula (M1), the remnant of a supernova that exploded on July 4,1054. It is 6,500 light years away and found in the constellation Taurus. #astronomy #astrophotography #seestar #fourthofjuly

V462 Lupi, 12 days after it turned nova. Imaged ~ 8 degrees above the southern horizon. The comparison star is HD 13380 (HR Lupi) below the nova, at the center of the image. #nova #astronomy #astrophotography #dwarf3

Waxing gibbous moon At the right angle of illumination, two features appear at the southern region of the moon: Rupes Recta (“Straight Wall”) - a 110 km by 2 to km wide fault The Eyes of Clavius - the rims of the 2 smaller craters w/in the Clavius crater #astronomy #astrophotography #dwarf3

The Trifid Nebula (M20) and its open cluster neighbor (M21) near Sagittarius first observed by Charles Messier on June 5, 1764 — 261 years ago today. Imaged with the Dwarf 3 with the duo band filter. #astronomy #astrophotography #dwarf3

A Study of the Sky, Herbert A. Howe (1896)

Asterisms named after Fr. Lucian Kemble: Kemble 1: Kemble’s Cascade (in Camelopardalis) Kemble 2: Little Queen or Mini- Cassiopeia (in Draco) Kemble 3: Kemble’s Kite ( between Cassiopeia and Camelopardalis) #astronomy #astrophotography #asterism #seestarS50 #dwarf3

Beautiful spots today at regions 4079 (34 spots) on the left and 4076 (1 spot) on the right. #sunspots #astronomy #astrophotography #seestar #solarastronomy

A night sky of wonder and beauty: a New Moon, a War God hounded by Bees (Mars and the Beehive Cluster), a Thousands Suns next to a seeming Obsidian Void (M9 and Barnard 64)

In the Great Hercules Cluster (M13), three relatively dark lanes nearly 120 degrees apart seemingly form a propeller. This was first reported by Bindon Stoney in 1850. Globular clusters may look the same but each has its own special traits. #astronomy #astrophotography #dwarf3

Happy #EarthDay, fellow space travellers!

This is the home star of exoplanet K2-18b. It is a red dwarf about 124 light years away in Leo. The bright star to the right is HD 99904 for reference. #astronomy #astrophotography #reddwarf #dwarf3 @kat-astro-bot.bsky.social

From last night: here's 67 minutes worth of asteroid (8) Flora passing in front of galaxy NGC 3628. 🔭

The #Dwarf3 sensor nicely fits Kemble’s Cascade (Kemble 1), an asterism of about 20 stars in the constellation Camelopardalis. It starts from the upper right and ends at the open cluster, NGC 1502 at the lower left. A single 15 sec shot vs a 4.5 min stack. #astronomy #astrophotography #asterism

The Sun was masked but it could not be silenced. April 8,2024. Eclipse math: The difference between a 99% eclipse and a total solar eclipse is still 100%. Go see one. #solareclipse #eclipse #astronomy #astrophotography

WATCH: This visualization reveals the stars of the Orion constellation in three dimensions. Watch as the familiar pattern on the sky distorts into a whole new perspective. 🔭 🧪 youtube.com/shorts/Gwo94...

While imaging the faint dwarf galaxy just above Regulus in Leo last February, I noticed a trail develop nearby after about an hour of integration time. It was pointed out to me by @palomarskies.bsky.social that it was asteroid (526) Jena. #astronomy #astrophotography #seestar #asteroids

More eclipse. You can see the Moon's relief against a sea of solar granules. And it looks like the Mandelbrot set is coming from the left 😆 🧪 🔭

Skies cleared up just enough to catch the end of the #eclipse. #solareclipse #astronomy #astrophotography

An interesting asterism in Draco. Almost like a little Cassiopeia. #astronomy #astrophotography #seestar @kat-astro-bot.bsky.social

Vera Rubin has been selected to be featured on the back of a quarter. She is the first astronomer to be honored this way. Read about her research on the Andromeda galaxy and how it led to the discovery of dark matter in this article written by Rubin herself. doi.org/10.1063/1.24... 🔭 #WomenInStem

How does experiencing 16 sunrises and 16 sunsets every day change your perception of time?
