The Baader T2-15 Adapter is a 2"-to-1.25" reducer that permits you to convert your 2" focuser for use with 1-1/4" eyepieces and accessories. A captive spring bronze lock ring guarantees protection of your eyepiece barrels from damage. The T2-15 reducer also incorporates two large nickel-plated brass knurled clamp screws that are oriented 90deg. apart.
The inclusion of two clamp screws results in a superior 3-point attachment that completely constrains your equipment from wobble, particularly important for imaging applications (typical single clamp screw adapters still allow some motion). Also, for those users that are physically unable to firmly grasp and tighten lock screws, the addition of a second screw doubles the locking force (i.e., particularly nice for those unable to grip tightly due to arthritis). The input side of the Baader 2" to 1.25" Reducer includes 48-mm filter threads and also includes a nested internal T-2 thread which enables you to use the reducer along with other T-2 system components.
