Magnificent photo of the International Space Station transiting the moon

On Saturday, space photographer John Kraus, age 17, captured this magnificent image of the International Space Station transiting the full moon. He took the photo using a Nikon D500 and Nikkor 200-500mm lens on an equatorial mount used for astrophotography. This wasn't a lucky shot. It took John weeks of planning. From Kraus's article at Petapixel:

As the ISS orbits Earth at 17,500mph, or roughly five miles per second, the transit lasted just 0.90 seconds.

This transit was visible from a narrow path stretching from the middle of Florida to the east coast. I was stationed in a very specific location, as being just several tenths of a mile can throw off a planned transit photo.

Given that the transit occurred so quickly, and I was in such a specific location, its natural to ask how I calculated the information required to take this photo. Luckily, I didnt have to, as theres a website dedicated to finding out transit info.
