10-inch Newtonian

This scope has a 10-inch f/6.85 Cer-vit mirror, with a very smooth figure that is accurate to 1/15 of a wave (measured with a Foucault tester and a five-zone mask). It give razor sharp, high contrast views and a small, 1.5 inch secondary. The mirror was signed and dated by Richard Fagin, who made the mirror in 1986.
