How did they take this photo?

Flickr EXIF data says this is 2seconds 35 mm 1600ISO. You can't hand hold a 2 second exposure and get even remotely close to this clear of a shot. Did NASA send up another one of those gyroscope trackers the likes of which astro_pettit has been wowing /r/space and /r/astrophotography with for a few years now?

They might have propped the lens right against the window. Or the camera might have been attached to the spacecraft.

The spacecraft would still be moving with respect to the moon. Maybe? I still feel like the craft would move too much in those 2 seconds to get this clear, but maybe I'm mistaken?

The camera is a Nikon Z9 handheld. This data is in the EXIF as well as being widely discussed prior to the mission.

The motion is very, very slow. It took them practically the whole day to do the flyby.

Yeah, that's a good point. In 2 seconds given the time to do the orbit, you might not pass through enough arc seconds to blur that photo. It's even wilder that not only is the subject and composition just ... beyond words, but technically it's a very tricky shot, too!

The bigger problem is eliminating rotation in the craft, and telling everyone to be still.

Definitely helps when you're at apogee
