NGC 253: Dusty Island Universe

Explanation:
Shiny NGC 253 is one of the brightest spiral galaxies visible, and also one of the dustiest. Some call it the Silver Coin Galaxy for its appearance in small telescopes, or just the Sculptor Galaxy for its location within the boundaries of the southern constellation Sculptor. Discovered in 1783 by mathematician and astronomer Caroline Herschel, the dusty island universe lies a mere 10 million light-years away. About 70 thousand light-years across, NGC 253 is the largest member of the Sculptor Group of Galaxies, the nearest to our own Local Group of Galaxies. In addition to its spiral dust lanes, tendrils of dust seem to be rising from its galactic disk laced with young star clusters and star forming regions in this colorful galaxy portrait. The high dust content accompanies frantic star formation, earning NGC 253 the designation of a starburst galaxy. NGC 253 is also known to be a strong source of high-energy x-rays and gamma rays, likely due to black holes near the galaxy's center.

I'm going out of town for a couple of days for a busy work trip -- I'll try to keep up with my daily posts, but if I don't, I think this image should tide you over for a bit...

This is the Hubble ULTRA Deep Field 🤩 most of what you see in this image are *GALAXIES* (not singular stars like our Sun, but galaxies like our Milky Way) -- if that's not something to think on for a while, idk what is!

Stella-Luna Observatory

Clear night, Moon bright

November 3, 2025 — The air was still and the moon so bright and clear tonight, we had to open up the observatory long enough to take a peek and a pic! Moon was 92% illuminated in its waxing gibbous phase, lighting the landscape around us, no flashlight required. Technical: Askar 103 APO telescope, TeleVue Powermate 2X Barlow, Canon EOS 5D Mk. 4 DSLR, single exposure.
