Terrestrial telescopes are generally manned, while space telescopes are unmanned. However, to a greater and greater extent, the people doing the observing are not the people actually manning the telescopes; the observations are done remotely from other universities around the world.
The various space telescopes, such as the Hubble, the Kepler, or the Spitzer, or the soon-to-be-launched Webb, are remotely controlled in the same manner that everything is controlled these days; remotely, via computer.
The Hubble Space Telescope is repaired by sending Space Shuttle missions to it. Astronauts conduct repairs, upgrades, and maintenance tasks during these missions. They replace faulty components, install new instruments, and perform tests to ensure the telescope's functionality.
There are a number of differences. First, they are in different orbits; the Hubble is higher than the ISS. The ISS is a lot bigger. Probably the most important difference is that the Hubble has a big telescope but no people, while the ISS has people but no big telescope.
Telescope eyepieces are important of any visual telescope. It is the main part of the telescope and is what determines how the object will look like through the telescope.
simplest possible telescope
The focal length of a telescope is directly related to the magnification in that the longer the focal length, the more magnification you get from the telsceope. How the focal length of a telescope relates to the length of the telescope itself depends on the design of the telescope. In a refracting telescope, the focal length is approximately the length of the telescope. In a reflecting telescope, the focal length is roughly two time the length of the telescope.

Manned is a verb (past tense of man) and an adjective (a manned post).
What we need now is a volunteer for our manned mission to Mars. They courageously manned the forward cannons.
The Hubble Space Telescope is a space telescope, not a space station or a space shuttle. It was launched into space in 1990 and orbits the Earth, capturing images of the universe. The telescope has provided valuable insights into the cosmos and has been serviced multiple times by space shuttle missions.
