Peridier Double Refractor



Julian Peridier had an observatory in Le Houga, France. In one dome he had a 12.3" Calver, and in the other dome he had this magnificent telescope. It is on a T. Cooke equatorial mount. The mount was modified by Manent, and he had two lenses made by Couder. One was a photographic lens (now lost), and the other was a visual lens. These were mounted in twin side-by-side tubes.

Manent also made a filar micrometer for Julian Peridier. The refractor was brought over but never assembled in this country, thus the older photo below was taken in France in the 60's or before.
