Question

Whats the farthest astronomical object that can be seen with a Schmidt-Cassegrain telescope?

Answer 1

If it's a 5-meter SC, you should be able to see 13 billion light years.  On the other hand, if you have a 5-meter 'scope, you got something that costs about $500 million at least.

Answer 2

3C 273, the brightest of the quasars, located in the constellation Virgo, about 2 billion light years away, at visual magnitude 12.8,  is probably the farthest thing you'll be able to see in an 8 -inch (20 cm) schmidt-Cass.

Answer 3

Yes: 3C273, which looks like a faint blue star in Virgo.

This all depends on how large your scope is, of course.
