Discover QtLens: a freeware for telescope design and optimisation

Discover Foucault: a freeware for telescope making and mirror polishing, under Windows

My telescopes and accessories for astronomy:

My 400mm, actually working on the mirror

This Newton, 200mm, more compact than the previous one

The telescope made with my girlfriend, diameter 200mm, all the mecanics in wood

This is a compact 150mm F/D=3 for the deep sky

My first telescope (200mm F/D=6)

This is my "head-up" finder, easy to build
