Just ran across this interactive demo of the relative size of objects in space. Interesting.

Re: The Size of Space
I love it! To take this a giant step further, according to a paper published several years ago, the radius of the entire universe is AT LEAST 250 times what is visible, based on the absence of visible curvature. My guess is that the universe is infinite, since this eliminates an arbitrary constant for the size of the universe. In any case, what we can ever see with any telescope is an infinitesimal part of all that exists.

20-inch homemade equatorial Newtonian with periscope
14-inch homemade equatorial Newtonian
10-inch Newtonian that folds flat
6-inch Russian Maksutov-Newtonian on Vixen equatorial mount
Too many small scopes and binoculars to mention
