I make the world's only binoculars designed for stargazing. You can 3D print and build your own @analogsky.bsky.social / https://analogsky.co/ Also graphic designer for the Terre Haute Gunblades.

Ok Blue Sky, using this app instead of X might improve your mental health a bit, but if you need a moment with the universe, I design stargazing 🔭🔭 binocular kits you can build easily yourself and find a few quiet moments of peace, by yourself or with friends. ✌️ analogsky.co

3d printed parts kit for building your own stargazing binoculars. User feedback from the hundreds of people who have built their own results in your kit coming with the most up-to-date design!

Side view of Analog Sky Ember, compact but powerful stargazing binoculars. Comfortable and hands-free, use telescope eyepieces to change the zoom all the way up to 100x with optional optics. See Saturn's rings and sunspots or zoom out for whole star clusters.

Top view of girl and her mom building Analog Sky Magic stargazing binoculars together. This kit + course takes you step-by-step through building your own binoculars that let you explore the sky like never before. See craters on the Moon, Saturn's rings, star clusters, galaxies, and constellations. Bring back the stars!

Front view of Analog Sky Heart, the first 80mm binoculars designed to be pointed at the night sky. Add telescope eyepieces to zoom from 11x - 133x. Breathtaking compositions of deep space objects in rich starfields at a price that was untouchable until now. Build your own and slip away into the cosmos.

Follow Venus the next few mornings, and you can see an unusual sight, as the planet transits (passes in front of) the open star cluster Messier 44 (Praesepe) in the heart of the constellation Cancer. Brilliant -4 magnitude Venus nicks the +4th magnitude cluster on Sunday, Monday and Tuesday morning.

I designed the biggest binoculars in the world (that you can buy) and they're for looking at outer space 🔭 🌌. Early access is a big step for our nano-scale mom-and-pop business to bring this model to life! www.analogsky.co/bloom

World's Biggest Binocular Telescope Model. 8" / 200mm Binoculars — Analog Sky

Analog Sky Bloom 8" reverse Newtonian binocular telescope gives you the most immersive views of the cosmos. Smart electronics combine with thoughtful design to create a whole new stargazing experience...

Big telescopes belong on Earth! A thrilling day for astronomy and humanity. Amazing what public funding can do. Where are the privately-funded pictures like this?

NSF–DOE Rubin Observatory @vrubinobs.bsky.social · Jun 23

The image offers a stunning variety of objects — from bright stars ranging from blue to red in color, to nearby blue spiral galaxies, to distant red galaxy groups — demonstrating the broad range of science made possible by Rubin data ✨🔭🧪

A sprawling, textured field of galaxies scattered across the deep black of space. It is filled with the delicate smudges and glowing cores of galaxies of many shapes, sizes and colors, as well as the bright multi-colored points of stars. To the lower left is a region filled with the hundreds of golden glittering gems of a distant galaxy cluster. In the foreground, below and right of center, two blue spiral galaxies look like eyes beneath the entangled mass of a triple galaxy merger in the upper right. A few bright blue points of foreground stars pierce the glittering tapestry.

Throughout the image, thousands of galaxies gather in clusters or are spread throughout, like glittering gems strewn on a table. Some are sharp-edged and spiral, like coiled ribbons; others round and diffuse, like polished pebbles. Still others are just smudges of various colors. The background is peppered with pinpoint stars in reds, yellows, and blues, crisp against the velvet black.

Just thinking of the Harvard computer women a century ago, who looked at images of the universe like this by eye to make discoveries. They revolutionized astronomy, and Rubin definitely will too!

Also, wow how excited would Henrietta Leavitt and Williamina Flemming be to see this! 🤩

Big binoculars incoming! 200mm parabolic mirror objectives. This is the first time mirror binoculars have been available since JMI stopped production. 2" focusers, IPD from 49-85mm. The optics all fit in carry-on luggage size. members.analogsky.co for the journey from CAD to first prototype!

Pretty! It's a nice one to watch rise in the east this time of year. For some reason the big open clusters surrounding Ophiuchus are not that well-known.

Mercury's elongation (distance from the Sun in the sky) is large enough for safe viewing before sunrise. Fun thing to see if you have to be awake in the morning

David Dickinson @astrodave.bsky.social · Apr 25

...and the show’s not over. Tomorrow sees one more chance to glimpse the slim crescent Moon just 36-24 hours prior to New as it slides by Mercury low in the dawn sky. You’ll need a clear, open horizon to the east, and binoculars (and an alarm clock!) will be a plus.

If you get a chance, I'd like to know how she keeps Chris Butler's toenails in her nylons without tearing them. Is it like a little sachet or maybe a Down to Earth reusable tea bag?

I love how YouTube gives you a panel of the comments you haven't replied to but seemingly no way to dismiss comments you don't *want* to reply to lol

Just reposting this so it's easy to find later to show my 12-year-old daughter. Sometimes I'm embarrassed I was so excited about the internet as a teenager in the 90s thinking we could share the collective knowledge of humanity when this was pretty much the whole point the whole time.

W-W says Meta let advertisers know when 13-17 y-os were feeling depressed saying, this is a good time to try to serve them an ad. "If a 13-year-old girl would delete a selfie that was considered a good time to try to sell her a beauty product. This was taken as a signal and shared with advertisers."
