telescopes [In reply to] Can't Post

All you need for a telescope are two convex lenses with different focal lengths.

Binoculars are basically a pair of telescopes folded up using totally internally reflecting prisms, and additional lenses to turn the image the right way up.

The technology is exactly the same, but the engineering is rather more complex.

If Leonado Da Vinci had been born 100 years later and known Galileo, we would have had binoculars in the 17th century.

A Far Dragon is the best kind...
