Baader Deluxe SCT 2" Visual Back with Integrated 2" Filter Holder
Baader Planetarium has a high-quality value solution for users of 2" eyepieces and accessories. The T2-17F 2" Deluxe Visual Back (Eyepiece Holder) incorporates dual oversized stainless thumbscrews plus a captive spring-bronze clamp ring to protect your eyepiece and accessory barrels from damage. This T2-17F 2" Deluxe Visual Back from Baader also includes an integrated 2" filter holder for even greater flexibility in applications.
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" 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 and making its installation a snap! Provides a solid fit! NOTE: Filter shown in photo is not included with this product.
