China is quietly preparing to build a gigantic telescope
High on the Tibetan Plateau, China appears to be laying the groundwork for what will be the largest optical telescope in the Northern Hemisphere - and perhaps briefly, in the world.

Tololo Lunar Eclipse Sky by Petr Horálek
On 14 March 2025, a total lunar eclipse occurred, especially visible over the Americas and the Pacific Ocean, observed from the NSF Cerro Tololo Inter-American Observatory in Chile. You can see how epic the sky was during totality, as the moon darkened enough for the majestic Milky Way, the faint belt of zodiacal light, and prominent airglow to stand out.
Why Did I Build a Dome 3,000km From Home?? (I’m Still Not Sure)
So... I kinda said yes to building an entire observatory dome... on the other side of Australia.
Everyone said we were insane. No crew. No backup. Just a dome, a dream, and way too many snacks.
This video is pure chaos: assembling a giant research-grade observatory from scratch, battling time, tools, and the Australian sun. We got sunburnt, we got stuck, and yes — we had at least one breakdown (maybe two).
But in the end? The dome stands. And we’re kinda proud of it.
Was it smart? Debatable.
Did we finish it? You’ll see.
Was it worth it? 1000%.

It’s SkyShed Observatory’s POD-S
A design rendering of the SkyShed POD-S Mark 4 – Tall observatory. Image Credit: SkyShed Observatories.Following the evaporation of our first observatory deal we revisited our pre-purchase research from two years ago. We quickly settled upon the SkyShed Observatories POD-S Mark IV in this project reset. Today we placed our order and paid for the ready-to-assemble kit.
While we were originally hoping for fiberglass construction, the POD-S is built from double-walled polyethylene — much the same as plastic garden sheds. The material actually provides some advantages over other construction but presents an interesting issue: daytime IR heating. It seems white poly is translucent to infrared light (solar heat rays) which causes the interior to heat up. We chose a light gray color which, while not the classic choice for a dome or observatory, we are told will allow less of interior heating, as it blocks more IR than the white color reflects. This flies in the face of the usual reflective white or metallic silver specified for observatories but those buildings aren’t made of polyethylene.
We don’t have production or delivery schedule information at this time (the order’s brand-new) but there are other things to do such as acquiring a new building permit, pulling electrical wire to the telescope pier site, building a warm/control room in a nearby shed.

Good News / Bad News
The bad news is that the deal we made for an observatory building is dead after two years of waiting. We received the news via email this morning. The final straw was that the manufacturer was unable –due to factors outside of his control– to ship the finished package! At a financial loss due to packaging costs, he canceled the deal and will issue a refund. The problem was so bad for him, he’s leaving the US market entirely!
The good news is that we have selected a product we had researched two years ago, along with our original choice. Ironically, we originally bypassed this manufacturer because it was going to be two years before their product could be shipped. Now they ship in 6 to 8 weeks!
We’ll post pictures and identify the new choice once we’ve closed that deal. We’re actually feeling pretty good about this. Except for the time lost not having an observatory.
A fine day for some solar astronomy and a fond farewell to AR4079
Our temporary observing setups are assembled on the base/floor of the planned observatory. The light orange bucket, at center, protects an empty electrical conduit that will provide utility power to a permanent pier that will be installed there. In the foreground is a table supporting a light shield for the laptop computer. The large tripod next to the table supports the white light imaging scope. In the background is the Sky-Watcher SolarQuest mount with our Coronado hydrogen-alpha solar scope attached.We’re still doing open-air astronomy though we have a nice, solid, clean, and level space to set up our gear! This is the setup we were using today to record the sunspot at active region 4079 as it is about to roll over the solar limb/horizon. Fortunately, though it’s a very temporary setup, the portable gear we use for casual solar imaging is fairly easy to set up.
From an unusual vantage point, a picture of the solar setup used today to record the passage of active region 4079 toward Sun’s horizon. The red object is the planetary camera.We continued experiments to determine what gear will work together for imaging. There were a few surprises and there’s need for more experimentation. What we settled on for today’s solar efforts is pictured above and includes: Askar 103 APO telescope, Meade LXD75 Goto Mount, TeleVue 2X Barlow, Baader Planetarium Safety Herschel Wedge, and ZWO ASI678MM monochrome planetary camera.
The sun as it appeared at 11:32 AM EDT on May 10, 2025. Sunspot/Active Region numbers are labeled in this image with AR4079 very near the solar western limb or edge.Although the sky was clear, seeing was a bit shaky so once again, sharpness wasn’t what we’d like. Still, in all, we got the shot we wanted and learned a few things about our astronomy equipment. Also, the sky was blue, the air was pleasant, and birds were singing, so not a bad way to spend a couple of hours.
A closeup view of the sunspot at AR4079. There is a bright line splitting the dark central umbra of the sunspot, the gray penumbra radiating in filaments around it. White cloud-like areas surround the sunspot, especially to its north; called plage, they are associated with areas of concentrated magnetic field.#2025 #AR4079 #astronomy #astrophotography #observatory #solar #solarastronomy #sun #sunspots #telescopes
Deckt sich leider mit meiner eigenen Erfahrung, viele Webserver sind einfach schlecht konfiguriert. Was mag die Ursache sein? Faulheit? Unwissenheit? Unklar.
