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

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

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

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