Today's sun. 🧪

Last night's moon and a comparison of images two days apart. Compare the November 4 image (first) with the Nov. 6 image (second). The slight shadows of the just-before-full and just-after-full moon bring out details near the edges. Notice the craters near the upper right edge on Nov. 6. 🧪

The airports that will see a 10% decrease in service are all hubs. That means that ALL US air travel except short local flights will be affected. Are we winning yet?

Too cloudy for the full moon tonight, but here's last night's almost-full moon. If I didn't have a telescope, I'd never appreciate the color differences due to the different mineral compositions. 🧪

Last night's moon before and after processing. An explanation follows in the comments.

Skipping the 60 Minutes interview. He will just lie and evade, and he HATES bad ratings.

October 26, 2025 sun 🧪

Let’s see… the government is shut down, Johnson won’t bring the House back, US Passports fall off the top 10 list, $200 million for a ballroom as 47 demolishes the East Wing, $172 million for two private jets for the puppy killer and $20 BILLION for Argentina. Are we winning yet?

M31, the Andromeda Galaxy. A barred spiral galaxy that is our closest galactic neighbor at 2.5 million light years distance.

So much winning... www.msn.com/en-us/money/...

This is the scariest Halloween I can recall.

Today's sun Oct. 17, 2025 🧪 One more image in the comments.

The Heart Nebula (SH2-190), an emission nebula about 7500 light years away in Cassiopeia. These images I post are better if you enlarge them. 🧪

Any bets that 47 lets the Gaza peace deal collapse now that he didn’t win the Nobel Peace Prize?

Last night's moon. 🧪

Happy to see that this year's Chemistry Nobel was awarded for actual chemistry and not biology again. The biologists got a nice award with the Medicine Nobel this year, so everybody wins!

I wasn't aware of this until I read the post. Honored. 🧪 www.linkedin.com/posts/jeol-l...

Second solar time lapse video from today. Best viewed full-screen, otherwise it's hard to see any activity. Look at the upper right for some faint but interesting details. 🧪

Northern Lagoon Nebula in the middle, Bubble Nebula in the upper right. Starry and star-reduced versions of the image. The Northern Lagoon nebula contains the largest known protostar. The open star cluster M52 is just to the right of the Bubble Nebula. 🧪

IC 5146, the Cocoon Nebula, about 4000 light years away in Cygnus. My software detected over 66,000 stars in the original image. You can also see a dark nebula that looks like a trail below the Cocoon nebula.🧪

Solar images from Sept. 20, 2025. An active day for prominences, and plenty of sunspots, too! 🧪

NGC 7380 and an enlarged view of the Wizard Nebula. About 3 hours from my back yard. 🧪

Video of solar prominences from Sept. 14, 2025 acquired for 45 minutes. There's activity on the top, but the most interesting activity is on the lower right. 🧪

Sh 2-185 is a cloud of ionized hydrogen about 10,000 light years away in Casseiopeia. One of the two nebulae (the red one) is called the Ghost of Casseiopeia. The bluer one is IC59.🧪

I wonder if 47 will autograph the radar footage and send it as a gift to Putin? abcnews.go.com/Internationa...

The level of cruelty in the administration is incomprehensible. #abrego www.msn.com/en-us/news/w...

NGC 7822, an emission nebula about 3000 years away in Cepheus. It's a star-forming region like the Eagle Nebula with the famous Pillars of Creation. The zoomed image shows the "pillars" in a section of this image (the Teddy Bear Nebula). I used a Hubble HOS palette to enhance different features.🧪

Today's H-alpha solar images before the intermittent clouds. 🧪

Lots of prominences on today's sun! 🧪

IC1396 in Cepheus. A large emission nebula about 2400 light years from here. The dark curly part is called the Elephant's Trunk Nebula.🧪

5 hours of data for the Crescent Nebula NGC6888 and its surrounding region. The nebula looks like a cat's face to me. The JPEGS are drastically reduced in size compared to the originals, but there's still a lot of detail. Click to enlarge to see the detailed images.🧪

I'll be at the ACS Fall meeting in Washington DC this week with JEOL. 🧪The title of my talk on Wednesday afternoon is "Pyrolysis. A Hot Topic!"

"Sunny day, keepin' the clouds away..." 🧪

A very active sun today! I'll process the other closeups and Ca K image tomorrow.

Happy to collaborate on this project on oil spill forensics! I anticipated this application way back when I first got DART working. It became a reality in the hands of the ECCC North Vancouver Lab with their extensive experience with oil spill investigations. 🧪 www.sepscience.com/q-a-with-dr-...

Last night's full moon taken with my little SeeStar S50. 🧪

I think I like the monochrome full disk solar image better than the color view. Aug. 9, 2025

I'm not really happy with the H-alpha image, but it's what I could get for an image of today's sun. I got some nice data for the Elephant's Trunk nebula last night. That's waiting to be processed.

I reprocessed my image of the Cygnus Loop to include a little more green because green is present in the emission nebula. I think it brings out more detail. 🧪

🧪Today's sun, August 2, 2025

The Cygnus Loop with the West Veil ("Witches Broom") Nebula and the East Veil Nebula. About 3 hours image collection on 7/28/2025 with a William Optics Redcat 71 WIFD telescope and ZWO AM2600MC camera. Not sure if Bluesky will show the entire image -- the thumbnail looks clipped. 🧪

Less busy a view of the sun than yesterday, but always interesting. 🧪

Busy day for the sun yesterday! 🧪

The sun has horns today. Ozzy...?
