This collimation eyepiece is very useful for precisely collimating the Newtonian reflector telescopes for better image quality.
This Cheshire collimating eyepiece is a combination of a Cheshire eyepiece and a sighting tube. The sighting tube's narrow field of view and crosshairs provide a centering reference for the telescope.
Main features:
- Eyepiece fitting diameter: 1.25" (31.75mm)
- Length: 148mm (5.8")
- Weight: 190g
- Material: full metal construction
- Eyecup: fold-down soft rubber eyecup
Note: The longer version of the Cheshire collimating eyepiece has sufficient length to allow the cross hairs to get closer to the secondary mirror of the telescope for a better view on secondary centering.
