Simulation Output

It’s come up more than once: how big a patch of sky is that long-exposure astrophoto showing? I just realized that I have the tool needed to answer that: Stellarium, available free for Mac, Windows and Linux.

In all of the following screenshots, the red rectangle is (if the dimensions I found on the net are correct) the view that a Micro Four Thirds camera (a mirrorless standard used by Panasonic and Olympus) would get through a telescope with a focal length of 1250mm. I only entered the dimensions once, so even if I got it wrong, it’s still consistent.

Earth, as seen from the Apollo 11 site (yes, if the scope and camera worked in vacuum, get off my back):
