USED Antares Mirror Star Diagonal (1.25\")

Optics like new, original box included. In excellent condition except for a scratch in the chrome barrel caused by the lock screw of the telescope it was formerly used in.

Replace a broken or missing star diagonal with the Antares mirror star diagonal. These diagonals produce a better image with less false color when compared to most cheap erect-image prisms.

Produces an image that is right-side-up, E/W reversed. For use with Refractors or Cassegrain-style scopes only.
