This straight-through viewing roof prism image erector is designed to use 1.25" Questar thread-in eyepieces only
on Questar Maksutov-Cassegrain telescopes. It is fully coated for high light transmission. It is connected to the Cassegrain focus at the rear of the Questar telescopes by means of a swivel coupling (not supplied). Swivel couplings (#13071 for a 3.5” Questar and #23032 for a 7” Questar) are part of the Questar camera coupling sets, but are also available separately. When the image erector is used, the Questar’s built-in Barlow lens will not function, as it is no longer in the optical path.
