Baader T-2 VariLock Extension Tube 29–46 mm Adjustable and Lockable

DESCRIPTION
The Baader T-2 VariLock 29–46 mm extension tube allows precise and stable optical path adjustments. Unlike typical helical focusers, it offers high torsional rigidity for imaging setups requiring reliable spacing.

Equipped with a millimeter scale and a knurled locking ring, it ensures exact positioning. The pre-installed T-2 male adapter (M42 x 0.75) can be replaced by the included S52 ring adapter to widen the clear aperture from 38 mm to 41 mm, ideal for full-frame imaging.

Included tools let you securely set and lock the extension length, and the design allows for camera rotation adjustment without changing focus. Ideal for fine-tuning camera position in critical imaging applications.
