| 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. Shipping is free on this Questar item if it is purchased with a Questar scope that is being drop-shipped to you from the Questar factory. Standard freight charges ($9.95 minimum) and a 14-day or longer delivery time apply if this item is purchased by itself as a special order item. Additional Questar freight and a $15 Questar drop-ship charge will apply if faster delivery is required and it must be drop-shipped to you from Questar.
