My article, about how a dream concept by Russell W. Porter was shaped into the curved stairs at Griffith Observatory, has been published today by the Springfield Telescope Makers on their stellafane.org homepage.

Phyllis "Pippa" Latour, born in 1921, was an SOE agent in WW2, who parachuted into Normandy in 1944.
She operated as a radio operator, sending 135 coded messages, crucial for D-Day operations.
"Pippa" passed away in 2023 aged 102.

Here’s a quick look at the Wizard Nebula (NGC 7380), an emission nebula and young star cluster in Cepheus, about 7,200 light-years away. Its glowing gas and dust form a shape that looks like a wizard, with hot young stars embedded in the cloud and still forming new stars.

IC 2118 is a faint reflection nebula illuminated by nearby supergiant star Rigel in Orion. It lies in the Eridanus constellation, at about 900 light-years.

HiPOD: A Flow Intersection
At this location, a portion of the Cerberus Fossae seems to intersect with the edge of a lava flow or other feature nearly perpendicular to the fossae. This could be a good location to investigate stratigraphic relationships.

Blue Origin has stacked the final tower segment for LC-36A!
Nearly 5 months ago New Glenn exploded on the pad during testing damaging the original tower and destroying the lightning tower. Now the tower is fully stacked awaiting the umbilical extensions ahead of New Glenn's Return To Flight on December 28th.
This is record pace for a pad rebuild that many said wouldn't happen until 2028, major congrats to the BO team! 👏👏

M 35 & NGC 2158

Seestar S50 Pro, 64 x 30 sec (32 min.) Bortle 8/9, clear, transparent, 52 °F. Seestar stack processed in AstroWizard w/RC Astro suite, PhotoShop 2026.
This is all the sub-images I took this morning for this object. It came out better than what the Seestar produced mid-stream during the acquisition, I think.
BTW, the newest Seestar update is now keeping a dark library that is accessible, unlike before. After I backed up the Seestar to my NAS, I found a new folder at the root of the storage called, "darklibrary." It had two sets of 30 sec darks in it that it took this morning.
Awesome! 👍

Fresh image of these two open star clusters. AI Enhance options at defaults. I boosted saturation a bit with IrfanView.

Some interesting celestial objects are starting to be visible over the northern horizon.
Here’s the Horsehead Nebula and Flame Nebula, two iconic deep-sky objects located in the constellation Orion. Both nebulae sit right next to the bright star Alnitak in Orion’s Belt.

Gamma Cygni Nebula and Sadr region Sh2-108
Sh2-108, also known as the Gamma Cygni Nebula or the Butterfly Nebula (IC 1318), is a vast emission nebula in the constellation Cygnus.
Spanning about 6 moon diameters, it visually surrounds the bright supergiant star Sadr but actually lies much deeper in space.

Iris Nebula NGC 7023
🔭 Seestar S30 Pro. 144 x 20 secs integration in EQ mode. Bortle 5. Processed in Siril and GraXpert.
The Iris Nebula (also called NGC 7023) is a beautiful reflection nebula in the constellation Cepheus, about 1,300 light-years away from Earth.
It gets its name because the glowing blue gas and dust around a bright central star form a delicate shape that looks like an iris flower or eye, with intricate dark lanes creating petal-like patterns.

I used the Seestar tools and did RGB histogram curves adjustments, then a little PS post-processing. Still taking.
