Space telescope located in outer solar system I want to pose a question from someone who's astronomy knowledge would fit neatly onto a single piece of paper so please bear this in mind with any comments or answers. I am interested and want to learn. I could not find a sane answer to this via a search engine.

The question: If in theory we placed another Hubble telescope (or similar instrument of at least equal or ideally more power) either on or very near the dwarf Pluto, as in in its orbit if we did not consider a ground mounted instrument, what if anything would or could we gain in astronomical knowledge ?

I do realise data transmission from such a distance would take time, power could be a concern and the fact if anything went wrong it would be beyond any sensible help, not to mention logistics in getting it there in the first place.

I also realise this is a completely hypothetical question too but I am genuinely curious if we would "see more" (so to speak) with such an instrument so far out.
The disadvantages would likely outweight the advantages.


It's cold out there. This makes it easier to keep an infra-red telescope cool
The sun's just a super-bright star.  This means more of the sky is visible and not in the glare of the sun. However you orbit so slowly that there will be a few objects that you won't be able to image because they are behind the sun for years.
There's no Earth to get in the way. The Earth blocks half the sky for Hubble. Putting a telescope on Pluto would have the same problem.
There's no space debris there (yet)


There may be other advantages, but compared to the immense difficulty of putting a probe into an 250 year orbit (you need to get it out there, with enough fuel left to put it into orbit) And the time it takes (you can't take much advantage of slingshots because you need to be in an orbit not just on an escape trajectory). And all the other disadvantages 


Saw something interesting, can't just get hubble to take a look, because there is a five hour light time.
No power, sun is too weak so depend on a box of plutonium or similar.
No nice high resolution images, sorry those take too long to download. Low resolution only.
We've never landed anything as complex and fragile as Hubble on any other body, And the landing has to be fully automatic.


And you don't get to see anything new because space is just as clear from Hubble's orbit as it is from Pluto.
