I realize this is one of those sorta fuzzy questions, but I am wondering if there are any other good examples of space telescopes with a similar mission to Hubble. Not really things like compton, Chandra, soho or things built for a single primary purpose.
Basically: General purpose or broad mission, optical telescopes using visible light, or UV or near visible IR, but excluding telescopes especially designed only for work in the lower thermal IR range, x-ray telescopes... that sort of thing.
Yes, it is a blurry line, but basically stuff with a lens and CCD and optical sensors, as opposed to a scintillation imager or something similar. And intended for broad use for stars, galaxies etc etc.
What is there to compare hubble to? I know it's pretty much the biggest and best, but are there any others in this nitch? were there?
The only thing that comes to mind ATM is some of the stuff on Skylab...
