I've seen a couple of shots of the ISS in front of the Sun before - always very impressive, but man, the perspective on this one. Incredible photography
That’s actually not that hard. You need a long lens. there are a few websites that tell you when the ISS crosses the sun in your area with exact time of the crossing. When the time comes, you set up your camera with a solar filter and do a burst for a few seconds.
I have done it a few times and I am always surprised that it works. While taking the pictures you see nothing so you have to totally rely on the exact time. But it always works out. Same for the moon.
I was somewhat surprised at the scale. The station appears quite big compared to the sun's disk, doesn't it? These astronomical conjunctions are always useful when trying to internalize the geometry in the Solar system.
Any idea how they manage to get clearly defined nebulae in the skyscapes? I've never seen it before; is it a new technique, filter or a composite of smaller angle shots?
This type of photography has recently become much more approachable thanks to products like the SeeStar S50/S30 and the Dwarf 3. These are smarter devices that can find and image most anything in the sky for you. And they retail for under $500.
You won’t be as good as these photos or people who send $10k rigs to be remotely operated at Starfront[0] in Brady, Texas - but you’ll be impressed with what you can get from almost anywhere.
My guess is very precise tracking to counter the earths orbit, long exposures, sensitive image sensors, massive lenses to capture the light, a remote location and luck.
You take many long exposure photographs of the same spot in the sky, stack them together, and then edit the images to make them look nice.
There is a ton of specialized equipment and software for the hobby - star trackers, astrophotography specific cameras, optics, camera control software, stacking software, and of course Adobe lightroom and photoshop
You can start out with just a digital camera/cellphone and tripod, and go all the way up to a full blown backyard observatory
I went to this exhibit at the weekend! Some truly awesome pictures (and a handful of runners up that left me wondering how easy it is to do, really)
One of the most interesting comparisons was how some pictures were a single shot, maybe 10-15 second exposure, and others were stacks of 700 or more images with exposures ranging from 60-400 seconds, taken over the course of a month.
It’s surprisingly easy to get a good shot of the Milky Way! I was blown away when I first bought a mirror less camera and stuck it on a cheap tripod. Most of the winning shots are also notable for composition and location. Deep sky shots with detail of galaxies and nebulae (anything zoomed in) require a much more complex and expensive gear, but wide angle is generally somewhat easy to capture if you have good dark skies. Just set up a 30 second exposure with settings as described here: https://kenrockwell.com/tech/how-to-photograph-the-milky-way...
Gorgeous photos, each category has so many incredible photos that I'd be hard pressed into picking a clear winner.
Btw, Royal Museums Greenwich is a lovely spot to spend some time during the weekend, either the museums/expositions or the parks around if the weather allows. Plus it has great views of London from the observatory.

But the angular size in your eyes maped to the Earth surface is 109m/408Km*6380Km = 1.7Km (1.0 mi) similar to the projection of Jupiter.
For objects that are far enough both calculations are equivalent, but for the size in a photo I think the second is the relevant one.

A museum. Just why??

Another great one is Cuiv The Lazy Geek. Very prolific and technical. He produces amazing images from light polluted Tokyo.
