TS-Optics 40 mm Triplet ED Guide Scope - F=132 mm - T2 and 1.25" connection

The 40 mm f/3.3 Triplet ED guiding scope with carbon tube offers very good optics and fits all common finder shoes.

  •  Triplet ED objective with 40 mm aperture and 132 mm focal length
  •  T2 and 1.25" connection
  •  Adjustment range of the focus: 15 mm
  •  Focus point 10 mm behind the T2 thread or 20 mm behind the inner T2 thread if the T2 extension is removed
  •  Fine adjustment by twisting with precise fixation by counter ring
  •  Stable metal bracket with dovetail bar, suitable for finder shoes from TS-Optics, Skywatcher, GSO and many more.
  •  Carbon tube
  •  Multi-coating on triplet objective for maximum transmission
  •  Especially well suited for guiding cameras with small pixels and high resolution

This guidescope is not a simple converted finder. The telescope was specially developed for tracking at high resolution with guiding cameras that have very small pixels. The triplet ED objective produces very precise star images and thus guarantees accurate tracking despite the short focal length of only 132 mm. Telescopes up to 10" aperture can thus be guided with the appropriate tracking camera.

On the camera side, the TSL40ED has a T2 thread and a screw-on 1.25" adapter, for example for guiding cameras with a 1.25" housing. With T2 extension rings (optional) you can get your camera at the optimal distance. Once you have achieved the exact focus, tighten the blue counter ring. Then nothing will move.

A holder and a dovetail bar are screwed onto the carbon tube, allowing you to insert the guide scope into all standard finder shoes, for example from Celestron, Skywatcher, TS-Optics and GSO.
