About this product

Model:  baad_ufc_2459110
Part Number:  2459110

The Baader-UFC Universal Filter Changer is thoughtfully designed and manufactured to a high standard. 

The filter chamber (UFC-Base) is the core part, which (at the time of writing) accepts three different filter sliders to suit 2", 50 mm round and 50x50 mm square filters. The filter sliders are held in place by an adjustable magnet and to ensure precise repeatable positioning a brass-pin mounted onto the far side of the filter-slider locates positively into the UFC filter base. The same pin enables you to easily eject the filter slider without applying undue pressure. 

Important: The Aux filter holders require a D50 slider to fit into.

Versatile application – for almost any telescope / camera

The camera-side of the UFC-Base (the filter-chamber) remains open towards the camera - until the matching camera-adapter gets mounted directly onto the UFC-Base. The purpose of this is to have the filters mounted with minimum distance to the image sensor, avoiding additional vignetting.

The telescope-side of the UFC-base carries a receptor with 6 clamp screws in 60° spacings, to mount all Baader-proprietory S 70-dovetail-adapters and spacers. A number of rigid UFC-S 70 spacer tubes are available in 5/15/40 mm length, as well as an ultra-stable S 70 VARI-LOCK spacer, engraved with Millimeter scale and seamlessly adjustable from 15 to 20 mm. These four spacers allow precise adaption for almost any backfocus situation, for both - back and prime focus - instrument configurations. Six tiny set screws also provide adjustment if necessary. 

Another set of telescope-adapters, with male S70 dovetail facing the camera-side, complete the assortment. This enables the UFC-assy onto almost any telescope, firmly and flexure free. For the RASA-adaptation Baader have milled this RASA/S70 adapter plate from stainless steel to enhance stiffness while retaining the extremely thin flange tolerances required for the RASA-design.

Simply replace the corresponding adapters on either side of the filter chamber when you change telescope or camera and want to continue using your existing filters.

Camera lenses can also be used with the UFC. The UFC-Base is fastened in front of the camera-lens by adding both the S70/SP54 adapter #2459134 and the retaining flange #2459121. One of the step-rings from the Hyperion-ring-system (#2958028 - 2958082) can also be used. Note filters should be mounted in reverse order when using the UFC-filter changer in front of camera lenses.
