The Baader 2" T2-17 Deluxe Clamping Eyepiece Holder incorporates dual oversized stainless thumbscrews plus a captive spring-bronze clamp ring to protect your eyepiece and accessory barrels from damage. 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 (all typical single clamp screw adapters still allow some motion). Also, for those users who 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 holder is precisely machined to fit your eyepieces with a minimum of slop, resulting in a close accurate fit that keeps your eyepiece properly centered on the optical axis. The T2-17 2" Eyepiece Clamp is also a key component for a number of common Astro T-2 System configurations, such as the Precision Amici Diagonal and Multi-Purpose Coma Corrector.
