A photo of the partially eclipsed moon, with just a sliver at it's lower right still in sunlight and overexposed with no detail. The rest of the moon is a gradient of increasing reddish color across it's middle, and very dark in it's upper left. Even as dark as it is, features are still visible, such as craters and dark seas or mare. Even some large craters are visible still. The moon is still in a segment of the Earth's shadow called the "Penumbra", Latin for 'almost shadow'. The deepest dark portion of the Earths shadow is called the "Umbra", Latin for 'shadow'. In the penumbra, direct sunlight no longer reaches the moon to reflect back strongly, as in the bright part to the lower right of the moon. The light that reflects back to us is refracted, or bent through our atmosphere, and are longer redder wavelengths. Like the light from all the Earth's sunsets and sunrises coloring the moon. A light haze of cloud is visible all around the moon, and a few faint stars shine in the blacker areas around the edges of the cloudiness.

I've found it's best to include clouds in scenes I decide to photograph. I mean, this is the PNW after all... 🌧️

That's about as good as it got, before the opaque clouds rolled in!

I'm glad I got to see as much as I did! It looks like it was a really nice ruddy eclipse this time!

Choreography of the Cosmos: Why the Sky Never Stands Still Join us for a journey into the night sky for the week starting January 18, 2026.

This week on Star Trails:
Why the night sky moves the way it does.

We talk rotation, orbits, retrograde motion, the Moon’s strange behavior, drifting stars, and why constellations are only temporary patterns.

Look up. You’re already in motion!

A photo of the gas giant planet Jupiter. Prominently featured are its Northern and Southern equatorial dark cloud bands, contrasting with much lighter colored equator clouds, and lighter areas toward the poles at top and bottom. The planet occupies the center of the image in a circular area that you could cover with your finger. The rest of the image is dark black. I could have waited another hour or more to wait for the Great Red Spot to rotate into view on the face of the planet, but my feet and hands were getting numb from the cold out on this night. 🥶

Last night was full of technical foibles and follies. 🤪 But considering this was the first telescopic astro session after moving, I'll take it! #Jupiter and its equatorial dark cloud bands.

A night sky photo full of stars. The brightest one sits above center left, and is many times brighter than the next brightest. It is not a star, but the gas giant planet Jupiter. At this resolution and field of view, Jupiter's moons are not visible. There is a small star next to Jupiter at about it's 6 o'clock position. The two brightest stars of the constellation Gemini are at top center, and at top center right. The one at top center is Pollux, and the one to the right is Castor. Tracing a line down from them each, roughly parallel to the bottom of the image toward the left, there are two "foot" stars for each twin. The left one, roughly middle lower left center is bluer, and almost directly to the right is a redder one, just right of bottom center. If you can see toward almost the bottom right corner, there is a fuzzy, or blurry patch, which is a distant tight cluster of stars associated with each other. Known to astronomers as M35, or The Shoe-Buckle Cluster, because it is where one of the twins shoes might be imagined. It is almost 3,000 light years away. And right below it is another fuzzy patch, though much dimmer. It is another smaller star cluster (NGC 2158), and it looks smaller and dimmer because it is nearly 12,000 light years away. All the many stars visible in this image are within our Milky Way Galaxy

A close up photo of a star studded night sky with several prominent bright stars toward the center of the image. This is The Pleiades star cluster. Called "The Seven Sisters", and many other names in different cultures around the world that have seen it through our shared history. Though the whole image contains stars all over, the main stars at center are brightest, and stand out easily. Roughly, seven of them form a small close group that is shaped like a small ladle with s very short handle with two stars at the end of the handle. The opposite side of the ladle cup has two stars at the tip of the cups right hand tip. The Pleiades cluster has far more than just seven stars that astronomers have found are truly associated with the cluster. The total number is likely in excess of 1,000 members. Only a handful are actually visible. The main stars we see in this image are hot young stars that are a characteristic blue color. There is also some faint wispy nebulosity visible. The nebulosity is not part of the cluster, but caused by some interstellar gas in the light path to us. The stars that show the nebulosity the best are the inner, upper right side cup rim star, and the lower left bottom cup base. Longer exposures and filtered light images can capture much more diffuse dust and gas. Other colors that can be seen in stars around the main cluster are reddish and yellow to orange. Between all the stars is deep dark background.

The Pleiades, from last night (1-16-26).
This is a combination of 11 - 60 second images, so a total of 11 minutes of exposure. The ISO was 200. Processed and edited in Sequator and LRc.

A deep sky astrophotograph imaged on 10/17/25 as Comet C2025 R2 Swan passed though the same field of view as the Eagle nebula M16 upper right, and the Swan (or Omega) nebula M17 lower left. This comet is currently not displaying any characteristic tail so only the green head of the comet is visible. Photographed in bortle 7 skies with a OMDS OM-1 full spectrum camera, STC Optics MS Astro filter, OMDS 50-200/2.8 lens at 186mm, f4, Skywatcher SA-2i mount. 109 frames at 25 sec., iso1000. Processed in Siril, finished in Photoshop.

Alt text: Text describes C20, also known as the North American Nebula, located about 1,800 light-years away in the Cygnus constellation. The nebula is an emission nebula. The observer captured around 400 one-minute exposures using a dual-band filter that isolates Hα (656.3 nm), OIII (500.7 nm), and Hβ (486 nm) wavelengths. This setup records only light from hydrogen alpha, hydrogen beta, and oxygen III emissions over 6.5 hours of total viewing.

A dense star field in deep space with countless white stars scattered across a dark sky. Nebulous clouds of reddish-brown gas and dust weave through the scene, creating bright and dark regions with subtle texture. Some areas are more heavily populated with stars, while dark patches indicate interstellar dust blocking starlight. The image has a cosmic, ethereal quality, showcasing the vastness of the Milky Way. This is C20 (Caldwell) or the "North American Nebula", ~1,800 light-years away, in the Cygnus constellation. It's an emission nebula I shot ~400 images of at 60 seconds apiece with a dual-band filter that allows only Hα (656.3nm), OIII (500.7nm), and Hβ (486nm) light. This means only light emitted by hydrogen alpha and beta, and oxygen 3 was captured by my scope across 6.5 hours of viewing.

The North American and Pelican Nebulas are lower left, the Veil Nebulas are lower right, the small Crescent Nebula is top center with Sadr below that. This image uses 202 x 40 second exposures during a dark new moon from Savannah, GA USA.
