297 - Gregorian telescope made of gilded brass by Paris in Paris, circa 1740–1750

Gregorian telescope made of gilded brass by Paris in Paris, circa 1740–1750 Gilded brass, leather; optical tube: 41 cm long and 6.5 cm in diameter; case: 48 x 17 x 11 cm. A two-mirror reflecting telescope known as a Gregorian telescope, made here of gilded brass and leather, and signed “Paris à Paris,” referring to Claude Paris, who was active from the early 1730s through 1763. The telescope is complete with its two original mirrors, its eyepiece, its objective cap, and its opaque glass eyecup, which serves as a solar filter. It has retained its original tripod and its wooden carrying case. A few flaws in the leather; otherwise, in very good condition.
