The Baader UFC Filter Slider allows you to quickly and easily swap out filters with the Baader UFC Filter Changer. Just one click of the brass pin on the bottom of the slider releases it from the magnetic fixtures for easy removal. The 2" filter slider is compatible with 2" filters with a cell up to 6mm in height. 50mm round and 50 x 50mm square filter sliders are also available. Smaller filters can be used with the 50mm round filter slider with additional auxiliary adapters.

Note: The UFC filter slider includes a washer which will prevent the filter from unscrewing during use.

The Baader UFC Universal Filter Changer is an incredibly versatile modular filter holder system with adapters for a wide range of telescopes and imaging trains, including the Celestron RASA series and even camera lenses.

Every component of the UFC system is precisely machined and designed so that no flexure is introduced into the imaging train. The adjustable magnet allows you to exactly tune the retaining force and positioning of the filter for repeatable flat frames.

Below is a diagram showing the many different camera- and telescope-side adapters, extension rings and filter holders that are available in the UFC system, with over 30 different items to choose from. While it may look complicated, it is simply a matter of matching the telescope adapter and camera adapter to the main body and selecting a suitable filter holder.

 

 The low profile and shape of the UFC makes it suitable for use with the Celestron RASA / Hyperstar system, where traditional filter wheels would block too much of the light path. It will also fit between a diagonal and SCT without causing focusing issues.

The camera-side of the UFC Base 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 the Baader S70 dovetail adapters and spacers. A number of rigid UFC-S70 extension tubes are available in 5, 15 & 40mm lengths, as well as an ultra-stable S70 VARI-LOCK spacer, engraved with millimeter scale and being seamlessly adjustable from 15 to 20mm.

 

 

Even camera lenses can be used with the UFC system. In this case, the UFC Base will be fastened in front of the lens by adding both the S70/SP54 adapter #BA2459134 and the retaining flange #BA2459121, as well as one of the many step-rings of the Hyperion-ring-system (#BA2958028 - BA2958082). Note that filters ought to be mounted in reverse order when using the UFC-filter changer in front of camera lenses. Feel free to contact us for more information!
