Andromeda galaxy from ISS looking zenith away from Earth horizon.
This is a 1 second exposure with an 85mm lens, f1.4, ISO 6400, using my orbital sidereal drive that tracks the stars. Without this drive, a 1/30th second exposure (using 85mm lens) was the longest without having stars recorded as streaks so this is 30 times longer than previously possible.
When exo-atmospheric, the dark view of space allows nebular detail to be seen in a shortish exposures. The "wings" on the brighter stars are due to the optical aberrations in the acrylic scratch pane needed to protect the window.
