Caught a comet tonight! I stacked 75 images of Comet C/2025 A6 (Lemmon), using my Canon 60D/300mm lens. Wish I could do better! I aligned all the images on the comet nucleus, showing some movement relative to stars and a satellite?

I captured my first 22-degree solar halo with sun dogs!

Finally freeing up laptop storage by deleting 10 years’ worth of “bad astronomy.” Thousands of giant .CR2 files of blurry stars, overexposed moons, and what I once swore was Saturn but was clearly just camera shake or bad focus. Hoping to make a new gallery at the end of it all!

A satellite photo of a volcano taken from space FROM THE SIDE
Just spent some time digging through old Maxar/DigitalGlobe blogs to find a reference image and found this incredible capture of Mt Fuji. Incredible.
The satellite was only three degrees above the horizon when it captured this image.

Sun rising at 7:13am ET, with some sunspots visible! First two images taken with my iPhone 16 Pro in Raw Max @ 25x zoom, exposure -2.0 and brightness slider turned to lowest setting. Last image is current data from NASA’s Solar Dynamics Observatory (different orientation than my pics)

Thank you NASA & JPL for my surprise mail this weekend! Being present for the 2024 total solar eclipse at Tupper Lake, NY was the astronomical highlight of my life. Check out my timelapse video of totality!

#NASARoman: NASA has successfully joined the sunshade to the Roman observatory’s ‘exoskeleton.’
The visor-like sunshade will help prevent unwanted light from entering the telescope: go.nasa.gov/4hQItFR

Nearing the end of book One of the Silo series and thought I found a hidden note on “precious paper” tucked into the spine- IYKYK. I’m really sitting here trying to peel it out carefully to see if it’s a secret message, or just a manufacturing defect. How cool would that be?

Ok. Chill out, Kevin.
Here’s one of my absolute favorites from the Cassini mission: Saturn on September 13 2017. The data for it was downlinked only hours before Cassini descended into Saturn. I was so excited when the data did come down, I ran outside and showed a gathering of friends :-)

Behind the scenes from last night’s Lunar occultation of Mars 🔭
✅ I used SkySafari Pro to plan the occultation start timing.
✅ Inside & warm I setup my Sky-Watcher USA SkyMax127 and AZ-GTi mount, connected to a 2x Barlow, universal variable adapter with a 20mm 1.25” plossl lens inside, & Canon 60D.
