Description

The wait is over. Baader Planetarium has developed the big brother to their acclaimed 1¼” Clicklock clamp. The new 2" Clicklock Eyepiece Clamp brings eyepiece holders into the 21st century. Gone are the cumbersome thumbscrews and fumbling in the dark. Gone are imprecise and wobbly holders. Now, with a simple twist, 2" eyepieces and accessories are instantly locked with such strength that they can literally support an entire telescope without slippage.

Simply grasp the rubber-knurled outer collar and lightly twist - that's all there is to it.

  • 3-point clamping guarantees consistent centering and the complete absence of wobble.
  • No-Marring of your fine eyepieces and accessories.
  • Knurled Clamp Lever is also provided for added convenience and to give a quick visual indication of clamp position *.
  • 20degree Rotation is all that is required. Very low force required to rotate.
  • Absolutely no sag or misalignment, even for heavy and long accessories.
  • Versions to fit most popular telescopes.

Schmidt Cassegrain Telescopes

Owners of all popular SCTs will find the Baader 2" Clicklock to be the perfect way to add 2" capability to their scope.

Directly mounts to the 2" threads on all popular SCTs (Celestron, Meade). Can also be converted to Internal T-threads for use on T2 components (ie, T2 Diagonals) with a T2-28a Expanding Ring.

Astro-Physics and TEC Refractors

The ideal solution for Astro-Physics refractor owners. With a single twist the 2" Clicklock clamp grips securely at 3 points, without marring. Ideal for imagers and visual users.

Physical length of 31mm, consumes just 20mm of Back-Focus when focuser is fully retracted.

Owners of TEC and other Refractors with the Feather Touch 4" focuser can also take advantage of the superior clamping of the Baader Clicklock Eyepiece Holder. Will not slip or sag under any load!

Note: Requires the use of the Feather Touch AP2.7" threaded back (available from Feather Touch or Telescope Engineering Company)

Takahashi Refractors and Cassegrains

The Baader 2" Clicklock Eyepiece Holder replaces the crude stock eyepiece clamp and gives Takahashi users the ultimate eyepiece holder for their fine refractor.

The eyepiece holder can also be detached from the M72/M64 portion to expose M68 threads. This permits use of Baader's M68 Extension Tubes to enable robust and convenient spacing of the holder for adjustment of telescope back-focus.

Fits all Takashi refractors with M72 thread (FS-102, TSA-102, FSQ-85 EDX, FSQ-106N, FSQ-106 ED series, TOA-130S and F and TOA 150, FS-128, FS-152). Physical Length: 41mm.
