Any other #Nascom or #Gemini #vintagecomputing geeks out there? I inherited a rather large collection from my late dad, but so far I've only found a handful of people why are into the #Galaxy computers made by Gemini Microcomputers Ltd., and none in the Fediverse yet. The Geminis were made in #England and mostly featured the #Zilog #z80 although they very briefly ventured into Motorola 68K world before throwing in the towel.

Celebrating Magic Wool Day ✨

A blue, purple, turquoise, pink, white portrait in a galaxy far, far away. We can see nine planets, each in a different size and distance, entangled with ribbons orbiting around the center of attention. One of my cute, blue-purple monster architects sits on the moon, knitting new planet features. The magic yarn will turn into wind, sand, stone, water, whatever it takes to bring more life into this wondrous space. On some of these planets, creatures are knitting, too, scarves and beanies, probably, for their tiny worlds with legs. Everything is cozy, and we are celebrating Magic Wool Day.

Well, it looks like you can't buy #Samsung any more:

"Unremovable #Spyware on Samsung Devices Comes Pre-installed on #Galaxy Series Devices"
https://cybersecuritynews.com/spyware-on-samsung-devices/amp/

"This has sparked outrage among consumers in countries such as Egypt, Saudi Arabia, and the UAE, where affordable Galaxy models are popular entry points into Android."

Another datapoint in favor of "in future, only #rich people can afford #privacy or #security". 😔

My latest processing assignment for my #astrophotography class, using data from the Gateway Remote Telescope.

This is the star-forming region CG 4, known as “God’s Hand” — although as a Star Wars fan I think of it as “Millennium Falcon Escaping the Jaws of the Giant Space Slug.” It’s my favorite astro image so far and I can’t get enough of it, so here are 3 versions: a wide view, a starless image, and a tighter crop. Details in the alt text.

Image of the star-forming region CG 4 (“God’s Hand”) — 1,300 light years away — which appears as a hand on an outstretched arm (or perhaps an open-mouthed creature with a long neck) extending from a luminous gas cloud in hues of pink and purple, in a field of hazy gases and multicolored stars. The “hand” or “mouth” appears to reach out to seize or devour a small spiral galaxy — ESO 257-19, which in reality is over 100 million light years further away. (H/t Wikipedia)

Data taken from the Amateur Astronomers Association’s Gateway Remote Telescope. Processed and edited by me using Siril, Starnet, and GIMP, with final edits in Snapseed. — Image of the star-forming region CG 4 (“God’s Hand”) — 1,300 light years away — which appears as a hand on an outstretched arm (or perhaps an open-mouthed creature with a long neck) extending from a luminous gas cloud in hues of pink and purple, in a field of hazy gases and multicolored stars.

Starless image of “God’s Hand” (the stars were extracted using the program Starnet). Only the smoky, hazy shapes of the luminous gas clouds, as well as the glow of the distant spiral galaxy, appear against the darkness. The effect is painterly and surreal.

A tighter crop of “God’s Hand,” focusing on the “arm” and “hand” gas cloud formation reaching out toward the spiral galaxy.

JWST NIRCam and MIRI image of Arp 142, also known as NGC 2936, NGC 2937, and UGC 5130, or the Penguin and the Egg.

The Penguin is a spiral galaxy whose shape has been distorted by the gravity of the elliptical Egg galaxy. The two are about 100,000 light-years apart and completed a close pass between 25 and 75 million years ago.

Arp 142, two interacting galaxies, observed in near- and mid-infrared light. At left is NGC 2937, nicknamed the Egg. Its center is brighter and whiter. There are six diffraction spikes atop its gauzy blue layers. At right is NGC 2936, nicknamed the Penguin. Its beak-like region points toward and above the Egg. Where the eye would be is a small, opaque yellow spiral. The Penguin’s distorted arms and orange dust lanes from the bird’s beak, back, and tail. The tail is wide and layered, like a beta fish’s tail. A semi-transparent blue hue traces the Penguin and extends from the galaxy, creating an upside-down U over top of both galaxies. At top right is another galaxy seen from the side, pointing roughly at a 45-degree angle. It is largely light blue. Its length appears approximately as long as the Egg’s height. One foreground star with large, bright blue diffraction spikes appears over top of the galaxy and another near it. The entire black background is filled with tiny, extremely distant galaxies.

Hubble image of Arp 220, also known as IC 4553.

Arp 220 is the aftermath of a collision between two spiral galaxies. The collision set off a burst of star formation, creating star clusters seen as bluish-white bright knots in this image.

This image is part of a collection of 59 images of merging galaxies released to celebrate Hubble's 18th anniversary in 2008.

An irregularly shaped galaxy fills most of the frame. The center is brighter, filled with a blue-white haze of stars that backlights a horizontal band of brown dust. Another area to the left of the core, almost as bright as the center is filled with a similar haze of stars and dotted with blue star clusters. To the right, the galaxy is less bright and more transparent. A faint hazy line extends almost vertically from the top of the galaxy. The black background of space is filled with stars and tiny background galaxies.

Hubble Interacting Galaxy Arp 220

Arp 220 appears to be a single, odd-looking galaxy, but is in fact a nearby example of the aftermath of a collision between two spiral galaxies. It is the brightest of the three galactic mergers closest to Earth, about 250 million light-years away in the constellation of...

Comet Lemmon (C/2025 A6) in the morning sky, just before twilight starts.

The camera was on a fixed tripod, no tracking, short telephoto lenses. 30 images were taken, then stacked with software.

This comet is faint to the naked eye, pretty in binoculars, and it's only seen in the northern hemisphere.

Note that in the first photo, if you zoom in close, some of the stars are elliptical smudges. Those are galaxies, tens of millions of light years away.

If you don't want to get up at 5:30 am, wait a day or two and it'll be visible low in the northwest in the evening sky, getting higher and moving south day by day.

If you can get away from bright city lights, this comet is bright enough that even a cell phone (especially propped on a stationary object) can get decent photos.

Please boost and share widely, especially the finder charts.

The comet has risen above distant conifers. The tail, though faint, stretches across most of the frame.

This is a crop of the entire image, taken with an 85mm lens. — The comet has risen above distant conifers. The tail, though faint, stretches across most of the frame. This is a crop of the entire image, taken with an 85mm lens.

This image is a crop from the entire frame, taken with a 135mm lens.

The head of the comet is green. The narrow ion tail is faint blue and has some texture/knots in it. the comet also has a wider, shorter dust tail that is slightly yellow. — This image is a crop from the entire frame, taken with a 135mm lens.

A finder chart for the morning of 18 October. Use the Big Dipper and its handle to orient yourself in the sky, then look to the right and a little lower than the lowest star of the handle. This shows the sky just before twilight starts.
