Description

Designed to be used with: Dedicated CCD Field Flatteners (175FF, 160FF and 13035FF) and Telecompressor Correctors (175TCC, 160TCC, 155TCC and QuadTCC).

This adapter is specifically designed to attach the above Field Flatteners and Telecompressor Correctors to QSI’s 500 and 600 series WSG medium format cameras. It has been precisely machined to maintain the critical spacing to the focal plane at the perfect 80.8mm. It utilizes the larger thread size of the QSI 2.156" adapter plate in order to minimize vignetting when using fast focal ratio telescopes. (2" nosepieces and T-threads are often too restrictive for today’s larger sized detector chips when used with fast scopes.)

It also provides a rigid method of attaching the camera to the optical system. This ensures the elimination of flexure from this part of the system.

This adapter has a net spacing distance of 1.11" (28.2 mm).

James ★★★★★

The thread pitch is a perfect match for my 160FF reducer, so there’s no wobble or tilt in the imaging train. It feels well-machined and solid, which gives me confidence during long exposures.

Lucy ★★★★★

Finally got this adapter to mate my QSI camera with the 160TCC corrector, and the threading is perfectly smooth—no cross-threading issues at all. Snug fit, no light leaks, and it solved my spacing problem for crisp stars.

Scarlett ★★★★★

Screwing this between my QSI and the 160FF was a perfect fit—no wobble, no shims needed, and the threads engaged smoothly right out of the bag. Backfocus held exactly where it needed to, so my stars are round corner to corner now.
