David Astro Visual Accessories

David Astro visual accessories cover the parts between the focuser and the eyepiece. Dielectric twist-lock diagonals with 99% reflectivity come in 1.25" and 2", and the twist-lock clamp holds the eyepiece centered without marking the barrel. A 1.25" 90° diagonal and a penta prism diagonal complete the choice.

The Premium Linear Erect Binoviewer gives two-eyed viewing with a correctly oriented image, well suited to the Moon and planets.
