| Consists of a swivel coupling and three adapter tubes that stack together in various combinations for prime focus, eyepiece projection, and Barlow photography with 7" Questar telescopes only. Uses optional Questar P-mount T-rings, eyepieces, and Barlows only. The swivel coupling attaches to the Cassegrain focus at the rear of the Questar control box and allows 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, or with Questar eyepieces, or with optional 1.5x and 2x Questar Barlows) for focal lengths of 2590mm to 8633mm. The eyepiece projection distance varies depending on number and arrangement of adapter tubes and where the eyepiece is positioned within the coupling stack. Needs optional Questar P-thread T-ring.
