A galaxy, nebula, supernova remnant, open cluster, globular cluster or similar extended non-solar system object.

 

I don't know what the proper definition is but I've always taken it to mean something like that... extended objects not gravitationally bound to the solar system.

I believe the definition is anything outside of the solar system 

 

Stuff orbits our sun out to a distance of about 2 light years apparently. Lets draw a line at Sedna.

That's about it. If they are an absolute beggar to image the definition is confirmed!

Pluto was a bit tough to image in any detail. Even the HST was crap, altho its images of Pluto and its moons as white dots were OK, that CGI of a blurry ball was next to useless.
