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?

Fuuuuucccccckkkkkk

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!

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)

Chandrayaan2 Orbiter high resolution camera at a distance of only about 100km (62 miles) I processed ISRO's publicly-available raw data and explain how I did this on my website in detail:

🚀👨‍🚀👨‍🚀 On this day: July 20, 1969: Neil Armstrong and Buzz Aldrin landed on the Moon during NASA's Apollo 11 mission. The clearest photos of the Apollo 11 & 12 Lunar Descent Stages that were left on the surface from were taken in 2021 by the Indian Space Research Organization's (ISRO)…

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!

FACT THREAD on New Interstellar Object #A11pl3Z

This story unfolded pretty fast yesterday for a few reasons. The object was discovered on July 1st UTC by the Asteroid Terrestrial-impact Last Alert System, or ATLAS team. A #NASA funded survey at the University of Hawaii. atlas.fallingstar.com 🔭🧪

Snapped this #sunset on my way home with some snow geese flying through.

Maybe, just maybe… everyone should stop getting so excited about SpaceX launches.

Finished “Wool” in 3 days! So good. Can’t wait to start the next two books on my shelf.

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?

That’s a beauty for sure.

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 :-)

✅ Moved outside to a concrete surface for improved stability vs. deck, leveled mount legs, used the SynScan Pro app to connect to the AZ-GTi WiFi. Worked for 20 minutes on focusing on lunar craters, then moved to Mars and fine-tuned focusing and camera video exposure and shutter speed settings.

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.
