Furthest and oldest

[Richard N]

What's the oldest thing that I am likely to see using my ST80 (80mm refractor)? And if it's the oldest thing - is it also the furthest?

[John]

Globular clusters are very, very old. Quite a few will be visible with your ST80. Messier 13 in Hercules, for example, is over 11 billion years old.

The most distant object that you will be able to see with the scope be a galaxy and you may be able to see some, as very, very faint patches of light, that are approaching 100 million light years away.
