This Questar 7" camera coupling set consists of a swivel coupling and three adapter tubes in various lengths that stack together in various combinations for prime focus, eyepiece projection, and Barlow photography with 7" Questar telescopes only. It is threaded for Questar-specific accessories and can use optional Questar P-mount T-rings, eyepieces, and Barlows only.

The swivel coupling threads into the Cassegrain focus at the rear of the 7" Questar control box. Thumbscrews allow the camera to be quickly rotated from a vertical to a horizontal orientation and locked in place at any orientation. The adapter tubes attach to the swivel coupling and are stacked in various combinations (alone for prime focus imaging, or with Questar eyepieces inserted into the adapter tubes for eyepiece projection photography, or with optional 1.5x and 2x Questar Barlows) to provide photographic focal lengths of 2590mm to 8633mm. The eyepiece projection distance varies depending on the number and arrangement of adapter tubes and where the eyepiece is positioned within the coupling stack. The Questar camera coupling set needs an optional Questar P-mount T-ring to connect to your camera.
