#Saturn in 2025 and over the last 5 years👇🏽 I imaged Saturn two nights back & have been imaging since 2020. Notice how the rings have gone from nearly face-on to edge-on? This is a 13 to 15 year cycle and is due to Saturn's ring tilt of 27deg to Earth's orbital plane. Saturn just had Equinox in May!

Haven’t posted anything in a while but here’s something that always amazes me: the Markarian Chain in Virgo is a gravitationally interacting set of 7 galaxies (or 8 depending on who you ask) but there’s many more lurking in the background… in fact 35 more!!👀🤩 Taken from my deck in SF Bay Area👇🏽

Did some first-time imaging with the ASIAir in the live-stacking mode, and boy did I catch some galaxies in their act! 🤩 👇🏽Just 10 min exposures (each 5sec)

At Yosemite Valley for spring break, and trying to stay away from the 24 hour news cycle (highly recommended for the times). The scenery is not only spectacular but the size of some of these formations is also truly mind boggling😳

There was a rainbow 🌈 earlier today, right across my work place.. amazing part was that it was almost at eye level.. felt like you could reach out & grab it.. hint of turning a corner?🤗

Happy Saturn ring-plane crossing Day!👇🏽😎 This is a composite of my own takes of Saturn over the last few years. Looking forward to imagining Saturn in the fall when the rings will still be near invisible!🫥

It's #Saturn ring-plane crossing day! A once in a 13-15 yr event when Saturn's rings are edge on, as viewed from Earth, making them appear to disappear! I'm so infuriated that the Sun is in the way meaning no-one will see it! 😡 We'll just have to imagine it 😞 👇The last time it was seen in 1995. 🔭🧪

Caught this pair a short while back. Bay Area, Calif Venus (upper right) and Mercury (lower left)

The magnificent pair of interacting galaxies, M81 and M82 from my deck👇🏽 M81 aka Bode’s galaxy is a grand design spiral galaxy. M82 aka the Cigar is a starburst galaxy. Repeated encounters between the two is triggering star formation in M82 but also tearing it apart #astronomy #astrophotography

This is the last four years of Saturn … Equinox is coming 🔜!

Venus & Saturn conjunction earlier today 👇🏽 While they are two degrees or four Moon-widths apart from one another in our skies, in reality they are over a billion and a half kms apart Their true distance scale in the alt-txt

I didn’t get to capture the occultation of Mars by the Moon on video this time (too low / clouds) but I did make a video last time it happened (on 2022-Dec-7) This is ingress👇🏽 1/2

👇🏽Eath’s “evil twin”, our closest neighbor in space (apart from the Moon) About the same size as the Earth and formed of the same materials, but a runaway greenhouse effect means surface temps over 900F and clouds formed of sulfuric acid This is Venus! #astronomy #astrophotography

Jupiter, Ganymede (left) and Io (right) from last week #astronomy #astrophotography

👇🏽this is 2 hrs on #Jupiter compressed… my best video yet!😎🤩 Watch the Great Red Spot rotate in & out from our perspective, Io (right) and Ganymede (left) in their orbit The best part? In the first frame, Ganymede is in a partial phase as it has just emerged.. that’s Jupiter’s shadow! #astronomy

My best ever pic of #Jupiter, from last night. Ganymede on the far left and Io on the right. The Great Red Spot bang in the middle🤩 Specs in the alt text #astronomy #astrophotography

Here’s the close up of the first frame showing the partial phase of Ganymede

Just returned from a trip to Bodega Bay, 60 mi up the CA coast from the Bay Area. Bortle 3 zone. Not the darkest skies but oh boy was it AWESOME! WE COULD SEE THE ANDROMEDA GALAXY WITH OUR BARE EYES!👀 And so many other Messier objects! 👇🏽DSLR pics at 20 sec exp Happy New Year to all! #astronomy

2025 is a centennial year, one that marks the end of the classical world for both the Largest and Smallest structures in the Universe, as had been known until then to Science. A short thread below 👇🏽

2025 is a square year coz 45^2 =2,025 January 1, 2025 is a Wednesday The last square year was 1936 (44^2) January 1, 1936 was a Wednesday The next square year will be 2116 (46^2) January 1, 2116 will be a… (wait for it).. Wednesday! 😎😎😎 #funfact

Watch Io emerge from #Jupiter ‘s glare👇🏽 in this 10 sec video (covering a little over 2 hours on Jupiter) The dark “spot” on Jupiter’s southern band is not Io.. it’s Io’s shadow 🕶️ #astrophotography

Happy #Festivus to all who celebrate! Even if you don’t, make the merry of it with a space🎄!

Jupiter and moons from a few nights back👇🏽 The Galilean moons seen here are (L to R): Europa, Io and Ganymede #astrophotography

My best pic of Uranus, from a couple of weeks back👇🏽 I’m pretty chuffed that I was able to get this with my setup😍 #astrophotography

Saturn from a couple of months back👇🏽 That’s right, Saturns rings are closing in from our perspective, and will be entirely edge-on by March (if we can see it then). This is a 27 year cycle (just like Earth, Saturn’s rotational axis is tilted wrt to its orbital plane) #astrophotography

Mars from a few nights back👇🏽 #astrophotography

Happy Winter Solstice! These photos were taken with a pinhole camera I made from a beer can and left out from Summer to Winter Solstice - a 6 month exposure. Bottom line = Winter Solstice. Top line = Summer Solstice. The lines are the Sun moving across the sky w/some reflections. No line = clouds

Happy winter solstice! Not only is it the shortest day of the year in the N Hemi with the Sun at its lowest point in the daytime sky but the ecliptic plane is high at night and the planets are primed for best viewing! All due to the Earth’s tilt! 👇🏽how to find the ecliptic and more in the alt-text

Jupiter & her kittens!

Some nebulae in the constellations of Orion & neighboring Monoceros… or should I say the “Drone” constellation? 🙄Will that catch on? 🤔 #astronomy #astrophotography

Our nearest large galactic neighbors are the Andromeda and Triangulum galaxies and you can image them right from your backyard like I did!👇🏽 Fun-fact: While Andromeda is heading towards us for a collision and merger, the Triangulum could also be joining in the fun! Whatshallwecallit? Milkomedulum?

For those of us old enough to remember Y2K, it feels surreal that we are almost a quarter century into the new millennium & I can’t stand it!!😳☹️
