Baader UFC Telescope-Sided Adapters

Please see Technical Specifications for more detail about each part!

The telescope-side of the UFC-base carries a receptor with 6 clamp screws in 60“_ spacings, to mount all the Baader-proprietory S 70-dovetail-adapters and spacers. A number of rigid UFC-S 70 spacer tubes is available in 5/15/40 mm length , as well as an ultra-stable S 70 VARI-LOCK spacer, engraved with Millimeter scale and being seamlessly adjustable from 15 to 20 mm. These four spacers will allow precise adaption with almost any backfocus situation, for both - back and prime focus - instrument configurations. Please accept the six tiny set screws, they are dearly necessary at times, when correct spacing becomes difficult. Each joint must be able to rotate, while requiring only a minimum of optical length.

Another set of telescope-adapters, with the male S70 dovetail facing the camera-side, completes the assortment, enabling the user to mount the UFC-assy onto almost any telescope firmly and flexure free. For the RASA-adaptation we even mill this RASA/S70 adapter plate from stainless steel, in order to provide the necessary stiffness while retaining the extremely thin flange tolerances required for the RASA-design.

Note that filters ought to be mounted in reverse order when using the UFC-filter changer in front of camera lenses.
