700mm. telescope for Chrissie. I've got a fairly long (forgotten) background in amateur astronomy.
The craters on the moon are fascinating but she really wants to know what that couple up the road are up too.

Cos they turn the images upside down?
Or was someone messing with my head?

No, you're correct.
Terrestrial telescopes, on the other hand, reverse the image left-to-right, so that what you see in the telescope is the mirror image of what you're looking at.

Putting the image right way up needs an extra lens or an extra mirror, and in astronomical telescopes you don't want to waste even a tiny bit of light with unnecessary refraction or reflection.
