An optional part of their Universal Filter Changer System, the Alpine Astronomical Baader UFC S70 15-20mm Dovetail VariLock Extension is placed between the UFC filter base and the telescope mounting adapter to provide an additional focal length if your camera system requires it. Available in multiple lengths, this extension can be stacked with other sizes to achieve the perfect position to capture the best images. This VariLock version has a continuously adjustable focal length from 15 to 20mm with a millimeter scale that allows precise and repeatable fine tuning.
