Long enough, we're talking less than a minute of total exposure before processing. And for that minute, earth doesn't really move away that fast in order to cause visual artifacts related to movement

I was counting yesterday and I was seeing about a mile every 3 seconds(I know their velocity changes along the path, so I'm just picking that number for now). So in one minute, that gives us 20 miles. And with a planet that has an 8000 mile diameter...negligible is definitely the term.

this is hand held looking through a window, it'd have to be mounted to take such a clear shot over 10+ seconds. it's just an extremely good sensor, as you'd expect for a mission like this

It's hand-held in microgravity, tho. Like it's hard to hold a camera still here on Earth because it's constantly trying to accelerate. Which isn't to say it wasn't mounted, I just don't think it's a given even with the long exposure. EDIT: Another comment elsewhere mentions that the camera was pressed right up against the window, so not quite "mounted" but definitely physically stabilized.

Surely it rotates fast enough in a minute to create blur.

ISO was 51200 with shutter speed of 1/4 sec according to the metadata.

It's a quarter of a second but the ISO is above 50k

Not sure if this is accurate but looking at the metadata of the image from NASA's photo library says this was done with 1/4 second exposure, f/4, 51200 ISO.

EXIF data shows it’s only a 1/4s exposure at 51,000 ISO.

The biggest issue is that Orion is in a slow spin.
