Hey all. Here's a question I've been wondering about. There's a website which shows you where on earth the ISS will be travelling over and when. What exactly is the ISS in the flat earth model? How come it can be observed using fairly run of the mill telescopes and cameras? Numerous photographers worldwide have captured the ISS during a transit of the moon. It is surprisingly easy to do! I personally observed the ISS pass over my city using a pretty cheap telescope I got when I was a kid. The beautiful thing about stuff like this is that it is objectively verifiable; you too can go outside with a Nikon P900, look up the date and location of the next lunar transit of the ISS, and then take pictures of it in transit! More expensive telescopes exist which can, and have taken high resolution pictures of the ISS, although you can't do this yourself unless you can afford a multi million dollar telescope!
