Baader Planetarium 2 Inch Deluxe Clamping Eyepiece Holder

Baader Planetarium has a high-quality solution for users of 2 inch eyepieces and accessories. The T2-17 2 inch 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 that are physically unable to firmly grasp and tighten lock screws, the addition of a second screw doubles the locking force (ie, 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.

For attachment, the holder is provided with an internal 2 inch thread, the same thread used on the back plates of all SCT telescopes. This permits the holder to be directly threaded onto SCTs, delivering the widest views possible.
