comment Is there a legend for these 88 HST images?
Heh, I also have a lot of stuff in my download folder that I wouldn't be able to source again! Anyway, I tried an image search with your image, and immediately got this this page, which links to a page with separate entries for many of the images, with descriptions. But I see you've answered it now anyway...

Where did you get the image from? Does it not have that information? You can almost certainly make life easier by identifying some of the pictures in the Hubble Heritage gallery. Then, for the remainder, I'd use image search on the individual clipped images.

comment Is it possible to use the stars to determine the passage of time?
I would guess that, after 10,000 years, most constellations would still be recognizable, if slightly distorted. So that would give a quick upper limit on the passage of time. In addition, you could also use the precession of the Earth's rotation axis by observing which star is the present pole star (or where a present pole star has moved to).
