2 Piece Cheshire collimation tool used for aligning the mirrors in a Newtonian design telescope. (Dobsonians are also Newtonian)
This Cheshire fits telescopes with 1.25″ focuser tubes.
Collimating your telescope mirrors ensure you always have the best focus and views.
The crosshair feature can be removed, and used as a standalone collimating focuser cap. This is useful when aligning the secondary mirror.
Youtube provides many tutorials on how to use a Cheshire collimator to tune your telescope.
