How far can I see with a telescope? Pretty far. Usually this question is asked when comparing two scopes, as in can I see farther with this telescope?. A bigger scope will show you more, but not necessarily farther. You don't really need to see farther, though. With the unaided eye, you can see 2.8 million light-years to the Andromeda Galaxy. Even a very small telescope can show you an object called 3C273, a quasar in Virgo that is 3 billion light-years distant. But most objects that are interesting to look at aren't that far away. What you really want with a telescope is light-gathering power to see fainter things, not farther things.
