comment Any freely available large stellar spectra catalog?
Have you not come across the Sloan Digital Sky Survey? From the information on the latest data release (DR12), it looks to me like there are as many as a million stellar spectra in there.

comment Why doesn't this paradox disprove (some) multiverse quantum gravitational theories?
Uh, call me crazy, but I think $1^{-n}=1$, so that sum diverges. Perhaps you meant $\sum_{n=0}^{\infty} 2^{-n}=2$?

comment What makes a really good observatory site, besides altitude?
Incidentally, the Tibetan plateau is an excellent observatory site. LCOGT is planning to set up a node there.

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...
