My favorite genre of astrophotography involving perfect alignment are photos of ISS transits over the Sun or Moon, e.g. [1], [2]. There is even a website which caluclates such transits [3]. Destin from "Smarter Every Day" made a video [4] about ISS transiting the Sun during an eclipse with all the details of preparations and setup.
They don’t explain how they took this photo, but I’m assuming they used the lens compression technique. In simple terms, the photographer takes a photo very far away from the foreground using a really long lens. This makes the background appear bigger, relative to the foreground.
It does, to the extent that you can’t normally take a 50mm shot and crop it to the same framing because of resolution limits - you’ll end up with a blurry 128x96px image. Maybe a fuji GFX could do it, but here the long range is what allows this particular image and perspective to be produced.
Completely opposite. Longer the lens, more the compression. To be able to get moon at that size with that resolution, you need “half a telescope”. Try shooting the moon with a 135mm lens, you’ll get a coin on the sky.
Worth nothing it's less to do with the lens and more about distance to the subject. If you took a wider angle shot and cropped it, it would look the same (albeit lower resolution).
Yes. That's because as you move away from the foreground object, the ratio of distances to foreground and background decreases. In the limit, this ratio approaches one, and you get an orthographic projection, where the projected size of objects (after zooming in) is independent of their distance from the camera.
