THIS is how you do #Astro alt text!
People that rely on alt text to understand what has been posted, or just curious minds, are not helped *at all* by just stating that the image is 'a galaxy', your gear list, or only the catalog number.
It takes little effort to do better.

So Artemis is faster, smarter and more powerful than Apollo. Good to know.

Definitely adding HA is worthwhile on M51

On Saturday, the #NHLBruins and @MAStateLottery honored Dr. Harold May as a Community All-Star. Dr. May was an original member of the first African American military pilots and aircrew, known as the Tuskegee Airmen, and later became the first Black surgical resident at Mass General Hospital. [1/3]

Thanks! It's coming along. I need the moon to go away so I can get some broadband data.

I totally get that. The 571 is a great sensor. I have a QHY 268C, and I kind of wish I had gone mono when I first got that.

Monochrome image of a galaxy as seen through a filter that only allows light from ionized hydrogen particles. The Galaxy is in the middle and relatively small in the frame. It is oval and mostly vertical. There's a bright core and lots of spirals of brighter areas around the core.

Livestack from last night of M63 in HA only

What camera do you have on your 120APO? I've been really happy with the Minicam8 + 120APO for galaxies

One of my favorites is The Space Between Worlds by @micaiahjohnson.bsky.social Really well-written and entertaining.

A nebula shaped like a flying seagull fills the frame in different wavelengths of light resulting in vibrant colors that define the makeup of the nebula.

Just finished up about 6hrs of data on the Seagull Nebula in Monoceros. It’s about 4000 ly from Earth. I used a OSC camera, a RedCat51 & 2 Antlia dual narrowband filters: one capturing Ha & OIII. The other capturing SII & Hb. I then split & recombined the channels in SHO pallet. 🔭 #Astrophotography

Four dogs, closeup on the front two, waiting to run the Iditarod. They're standing on snow as light snow falls, and they're wearing small blankets on their backs. Description from Vogue's website: "Natrah and Coki prepare to lead the team on the 11-mile kickoff course, wearing blankets made by Denise Newman and April Monroe. Photo: Emily Sullivan"

Two women sit on a leather couch making the blankets for the dogs. Above them are two photos of an Alaskan view and Iditarod dogs. Description from Vogue website: "Kate Chavez, one of the beadwork artists, working with her sister Brittany to make last-minute adjustments to the blankets before the Iditarod starts.

Closeup of one of the blankets, featuring beaded flowers and northern lights. Description from Vogue website: "A detail shot of a beaded blanket by Erika Scheffen and Keisha Green from Dawson City, Yukon. “There is so much meaning, from the northern lights to the stars. I put in the Big Dipper and Little Dipper, which Tr’ondëk Hwëch’in and many other [nations] have traditional stories about that have been passed down through generations orally,” says Scheffen. “I also added forget-me-nots to represent the Alaska state flower.” Photo: Emily Sullivan"

Closeup of another blanket, featuring a beaded dogs face surrounded by a circle and snowflakes. Description from Vogue's website: "A detail shot of a beaded blanket by April Monroe of Fairbanks, Alaska. “On this blanket is Jody’s sled dog Flash,” says Monroe. “He was a foundation dog for her team, and many of the dogs running the race with her today are his children and grandchildren.” Photo: Emily Sullivan"

Hän Gwich’in musher Jody Potts-Joseph has outfitted all 16 of her Iditarod dogs with handmade beaded blankets made by Alaska or Canadian First Nations artists! The time and love that went into these, wow...

A color photograph of Barbara Liskov, the pioneering American computer scientist, Turing Award winner, and MIT Institute Professor, standing in front of a large black chalkboard filled with dense handwritten mathematical and computer science notations. She is an older woman with short, curly hair, warm smile, and a friendly, engaging expression as she looks directly at the camera. She wears a light mint-green shirt or sweater with a collar. Behind her, the chalkboard is covered in complex equations, diagrams, symbols (including Greek letters like π, arrows, brackets, subscripts, superscripts, terms like "DB", "30sec", "Lop", "D", "T", "eichn", "P", "Joe", "Page", "aps", "uige", and various parentheses, integrals, and code-like fragments), suggesting an active lecture or research discussion on programming languages, data abstraction, or algorithms. The setting appears to be an academic classroom or office at MIT, conveying her enduring role as a mentor and innovator in computer science, particularly for contributions like abstract data types, the Liskov substitution principle, and object-oriented programming foundations. The overall mood is intellectual, approachable, and inspiring.

Computer scientist Barbara Liskov's work forms the foundation of modern software engineering.

She is best known for inventing data abstraction & the Liskov Substitution Principle, concepts that are now fundamental to how almost all modern software is written. #WomenInSTEM #WomensHistoryMonth (1/2)

Thanks!

A green parrot with a brown head in profile standing on one foot

I hear the #BirdOfTheDay theme is #SteppingOut and in that vein I present a Brown-hooded Parrot preparing to step out into the great unknown.

Just don't try it again next year

Red-eyed tree frog clinging to a small tree trunk. The frog is mostly green, with some blue on its sides and the inside of its legs. Its hands and feet are orange, and you can see most of one bright red eye with a vertical black pupil protruding from its head.

I've been very lucky to be able to visit Costa Rica, and got even luckier to see a Red-Eyed Tree Frog during the day. This almost instantly became one of my favorite photos I've taken.

this is the most bizarre thing i have seen in quite a while:

six radio telescope dish antennas at varying distances in the desert. Each antenna is illuminated in one of the pride colours. The Milky Way arches overhead.

It's Mardi Gras night, so time to once again share this fab image from Alex Cherney of CSIRO #ASKAP telescope core located at the Inyarrimanha Ilgari Bundara observatory, illuminated in pride colours.

Light, even radio light, is a spectrum.

Light is gay.

Universe makes the rules, not me.

It should be the government's responsibility to tell me how much I owe them/am owed as a refund. Why do I have to do anything other than submit or receive a payment?

MAKE AN EMERGENCY DONATION to Trans Continental Pipeline right now.

They are a Colorado based org that helps trans people relocate there and they are overwhelmed with requests. CO borders KS, and TCP has the infrastructure to help get people out.

GO DONATE.

Winter is coming...

I sincerely hope so

Looking forward to the bird-shaped Aurora

I particularly hated that they kept running ads during the female sliders' runs in the team skeleton event

I'm 2/14 for knowing the sound each photo represents. Presumably that's uncommonly low.

a man is standing in a hallway with a blue light behind him Alt: Geordie LaForge, rolling to make it out of Engineering under the lowering blast doors.

As I've been on a roll with Star Trek threads today, let's continue with this one: you know one of the best parts of Geordie's visor?

90% of the time, nobody fucking mentions it.
