BAADER UFC FILTER DRAWER FOR M42 CAMERAS

The Baader UFC Universal Filter Drawer for M42 cameras is a low profile filter holder for standard 2" mounted filters (additional sizes are compatible with separate adapters). On the camera side is a male M42 x 0.75 thread for connection to cameras with a matching female thread, as well as a female M48 x 0.75 thread on the telescope side for connection to common field flatteners/coma correctors. At only 16mm thick, the UFC is perfect for setups where backfocus is limited.

This bundle is made up of the following components:

• BA2459110 UFC Filter Base
• BA2459112 UFC Filter Slider 2"
• BA2459129 UFC M48 telescope adapter
• BA2459115 UFC M42 Camera adapter

Note: components are delivered unassembled. Click here for assembly instructions.

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 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.
