Farpoint 1.25 Inch Cheshire Collimator


Farpoint 1.25 Inch Cheshire Collimator is a simple tool that helps align the optical axes of the mirrors of a Newtonian Reflector, a process called collimation. This precision-machined, blue anodized alignment tool for 1.25″ apertures is practically indestructible and requires no batteries.

A Cheshire eyepiece or Cheshire collimator consists of a peephole that is inserted into the telescope focuser in place of the eyepiece. Ambient light falls on the brightly painted oblique back of the peephole. Images of this bright surface are reflected by the mirrors of a Newtonian Reflector and can thus be seen by a person peering through the hole. A Cheshire eyepiece contains no lenses or other polished optical surfaces.

Includes a mirror spotting template and triangle center spots to help simplify the process of center spotting a primary mirror.

We generally keep collimation tools in stock. However, sometimes we run out. If the item is not immediately in stock, we make it to order and it takes 7 to 10 days to ship. If you have not received a tracking number in that time, please email support@opticalstructures.com for information regarding your order.

Our standard acetate mirror center marking template works with mirrors up to 10”. If your mirror is larger, you can print out the file below, tape it together, and use it to mark your larger mirror.
