Baader 2" Standard Eyepiece Extension

Baader Planetarium offers two different 2" eyepiece extensions. 

The new 2" Deluxe Clicklock Extension incorporates Baader's innovative clicklock twist-lock mechanism,  providing the same ease of use and clamping force as the other 2" Clicklock accessories.  The 2" barrel can be removed to reveal the 2" SCT Clicklock Clamp (CLSC-2).  Optical path length is 47mm, wt 184g (6.5oz).

The 2" Standard Extension makes use of the lower cost thumscrew eyepiece clamp (T2-17), which utilizes two large thumbscrews for secure clamping, and a captive bronze compression ring to prevent marring.  Optical path length is 60mm.

Both incorporate removeable 2" barrels that are fully baffled to control stray light, and are threaded for 2" filters (M48).

• The Baader 2" Standard Extension includes two pieces, the Baader T2-17 2” Deluxe Clamping Eyepiece Holder, and a 2” barrel.

• The eyepiece holder portion of the extension uses two large thumbscrews for secure clamping, and a captive bronze compression ring to prevent marring.

• The optical path length is 60mm.

• Removable 2” barrel is fully baffled and threaded to accept 2” filters.
• Includes a dust plug and barrel cap to keep the interior clean when not in use.

The Baader Planetarium T2-17 2" Deluxe Clamping Eyepiece Holder has a captive spring-bronze clamp ring and dual oversized stainless thumbscrews to protect your eyepiece and accessory barrels from damaging. Completely constraining your wobble is the inclusion of the 2 point screws that result in a 3-point attachment. While most single clamp screws still allow some motion, having the 2 point screws narrows down such motion to a bare minimum. Also with having the 2 point screws, users with difficulty or who are physically unable to firmly grasp the thumbscrew now have an advantage of doubling the locking force with having 2 screws. The holder is precisely machined to fit your eyepieces with a minimum slop, resulting in a close accurate fit that keeps your eyepiece properly centered on the optical axis. The holder is provided with an internal 2" thread which is the same plate used on the back of SCT telescopes. This allows the holder to be directly threaded onto SCT's and in turn offering the widest views achievable.
