This image of home just came down from the Artemis II crew.
Taken after their translunar injection burn, there are aurorae at top right and lower left, and zodiacal light at lower right.

Sony A1 MKii can hit 102,400 for stills.
AFAIK anything past 32,000 is digitally expanded (which could be done with RAW post-processing).

The old Nikon D5, impressively, doesn’t seem to post-scale even at ISO 102400
“Old” high-end DSLRs are aging well, digital photography has been in the diminishing returns for a while now. You’re almost surely getting better pictures out of a 10 year old flagship than a brand new mid-level camera, and the “thoroughly tested” part matters a lot in spaceflight
Still surprises me that it’s a D5 of all things, but then my main camera is only a year newer than that one. Not sure I’d use a DSLR at this point though.
My 2015 Sony a7s2 has “native” iso to 102400, and expanded to 409600, but it was a special full frame low light sensor and it’s only 12MP (most from back then were 20-30MP with the same sized sensor.
