ISS overhead pass long exposures (Warning: large images)

[Regolith]

For most terminator lit views, the station is 700-900km away, or more.  Human eye resolution is about 1-2mrad (full open pupil), so a "pixel" is miles across at that range.  With 7x magnification, you are still around 1km resolution.

On a clear, good viewing night, to see structure on it, you will need a resultution of about 1-2 microrad, meaning a 10-20" telescope, and then, its going to be a very fuzzy blob.

Not quite. These images were taken using a 6" (150mm) refracting telescope. He was using some really high end gear, though.

It's also only visible in view for a second or two at most, even with a good wide-angle eyepiece.

So it was two times closer, with a scope twice as small, on a solar transit (non-emitting, but rather blocking source).  Makes sense, my "just did it in my head math" was within 25% or so.
