Nice image.
I estimate the pixel resolution at the ISS ≈ 1 meter. An astronaut on a spacewalk might be visible if face-on (maximum area) to the camera.
A pessimist is nothing more than an experienced optimist
Four years ago, when Grandson No.1 was old enough to be shown a sky object and young enough not to be sceptical, we showed him the ISS flying overhead on Christmas Eve, as Santa's Sleigh. I hope that after my criticism of the use of "Blood Moon" I may be forgiven a harmless little fable in favour of childhood wonder?
He now has a brother of that age, and so I clicked on the link above to find when the ISS might be visible, this Christmas. The link doesn't work! Try https://spotthestation.nasa.gov/ and you get straight to it. Happy Observations of Santa's Sleigh, everyone!

The "little fable" of the ISS as Santa's sleigh pales in comparison with the huge fable of Santa!

Oh, come on, Chris! It must be true, NORAD tracks him every Christmas!
And how do those presents arrive otherwise?
Don't listen, kids, that old killjoy will have you believe next that the Tooth Fairy is in league with Colgate!
I'm not arguing against presenting the fable. Just comparing the magnitude of the fables involved here!

<<The origins of the NORAD Tracks Santa programme began in the United States in 1955, when a Sears Roebuck store in Colorado Springs, Colorado, gave children a number to call a "Santa hotline".

The Director of Operations, Colonel Harry Shoup, received the first call for Santa and responded by claiming to children that there were signs on the radar that Santa was indeed heading south from the North Pole.

! like this ISS silhouette over the Moon! From the time I came to
Earth 'til now technology has progressed at an enormous rate! At this
rate we'll be driving flying saucers before you realize it! At any
rate; it is a fantastic photo!

That may be make believe; but it is way too scary! 🥶
I'm not understanding the image composition method here. Was a separate image of the gibbous moon - sans ISS - combined with some frames from that video that does show the ISS? If so, I fail to see the purpose.

I didn't see the connection either; but i loved the picture of the gibbous moon!

Presumably to take advantage of lucky imaging algorithms to get a very high resolution ISS image.

"Lucky"? So, was the ISS really transiting the moon in the position shown here, and just the ISS was "enhanced" using frames from the video? Or is this pic composed solely from the frames of the video? Still not clear to me, but I guess it doesn't really matter...

I don't know. If I were taking it with similar equipment, I'd build the ISS image out of the video sequence, and then overlay it on one of the single frames. That would make it a perfectly accurate representation of the event but with a higher resolution ISS image than is possible in a single frame. A perfectly reasonable technique, IMO.

I would have to agree.
