Starship launch from @ISS. We happened to be overhead!

Wonky star trails. During an ISS attitude change (orientation relative to earth and stars), I set up a time exposure through the Crew-9 Dragon window. These star trails trace the rotation of ISS during its change in orientation. The only stationary object in the field of view is the Dragon SpX-31 cargo vehicle. Nikon Z9, 8mm fisheye lens, f2.8, ISO 640, 15 second individual exposures assembled with Photoshop (adjustments to levels, contrast, color) to make an effective 24 minute exposure. Note, I do not have the computer power on orbit to correct for sensor noise with the corresponding dark frames; this will have to wait until I return to Earth.

Star trail out forward looking window. When observing Earth, I like the effect of an oval window. It adds a certain measure of aesthetics over that of a round window. However, when you are living in a metal can for six months at a time, I will be happy with any shape of window.   Nikon Z9, 8mm fisheye, 30 second exposures at f2.8, ISO 640, assembled in Photoshop to make an effective 30 minute time exposure.

This is what happens when you send an astrophotographer to space.
