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 https://t.co/Lrc44lMu6l homepage.

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
Oct 17th, 2026

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! 👍

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.

🔭 Seestar S30 Pro. 156 x 30 s integration (78 mins). Bortle 5/6.

Stacked and denoised in the app.

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.

🔭 Seestar S30 Pro in EQ mode and 30 sec exposures. 28 min total integration. Bortle 5. Processed in Siril and GraXpert.

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.

「魔女の横顔星雲」
先週末の好天に撮影した魔女の横顔星雲（NGC1909、IC2118）です。オリオン座の1等星リゲルの近くにある大変淡い反射星雲です。淡く難物ですが独特の形をして好きな星雲の一つです。

先々週の蔵王で撮影したシャーク星雲です！
画像処理に難儀し遅めの完成になりましたが、F6.7の非冷却カメラでもここまで写すことが出来ました！！
初めて2夜かけて撮影し、11時間の露光となりました。
暗黒星雲の画像処理って難しい…

80 years ago today, the first images of Earth from space were taken. A 35mm camera mounted on a captured V-2 rocket launched from White Sands Missile Range in New Mexico. This photo is a frame from the rocket's journey to 65 miles (105 km) above Earth's surface.

Timelapse of the rising Moon over the limb of Earth during the March 2025 lunar eclipse. Crew in orbit is lucky to see this a few times per year!

[Chris Hadfield @Cmdr_Hadfield]

I was seated in the audience front row, and recognised Heide's symptoms. The crew, behind her, couldn't see that she was about to faint, so I jumped onto the stage and luckily caught her in time. Ever since then, astronauts sit during the debriefs immediately post-spaceflight. Don't need anyone falling and getting hurt.

📹🌎 Spectaculaire : il y a 80 ans jour pour jour, le 24 octobre 1946, avaient lieu les premières prises de vue de la Terre depuis l’espace.

Une fusée V-2 décollait de White Sands pour atteindre 104,6 km d’altitude, emportant une caméra DeVry de 35 mm.
