A telescope?

A catadioptric telescope will be cheap and will give you very long focal length. They are usually quite slow, so you're going to be in diffraction territory. But you will not get anything like that with a regular photo lens. Not at a reasonable price. Also, you can use a Barlow lens with a telescope to increase its focal length (it's basically a teleconverter for telescopes). So a 2600mm will cost like $400 or so. But you'd have to read up on Mooon imaging techniques to get anything useful out of that.

TS Optics makes a "lens version" of such a telescope. A 1000mm f/10. If not for its unwieldy weight of 2.3 kg, I'd have already gave it a try.

Anyway, here's example from my SkyWatcher Mak102 with a focal reducer (around 900mm). At it's original 1300mm, it's not possible to fill full moon in the frame.

There's more Moon shots in my flickr album .
