Use our Cheshire collimator to get the most out of your Newtonian telescope you need to align or collimate the mirrors. It can take some time getting used to collimating both the secondary and primary mirrors and our Cheshire collimator as well as our laser collimator can make it much easier.
The Cheshire collimator for mirror (reflector) telescopes has a 45 degree plate for easier visual accuracy.
Collimation is the alignment of elements inside an optical system like a telescope. Collimating a telescope consists of adjusting the tilt and position of the mirrors and lenses to ensure that the focal point reaches optimum focus at the point from which the image will be viewed (the telescope eyepiece or possibly a camera for astrophotography).
Many factors can affect the collimation of your optical system and can cause the mirrors to move slightly such as vibrations from movement or expansion and contraction from temperature changes. A mirror which is not properly collimated will cause the light path to shift. The changes to the optical system’s light path will cause an image to become blurry and or unviewable.
In order to ensure that you’re seeing the best images your telescope is capable of providing, you should collimate you telescope before each use. You should also collimate your telescope any time images become blurry.
This Cheshire collimator is great for use as you travel with your telescope as well because it is so small and is less likely to break if you drop it than your average laser collimator. Great to have on the road for a quick collimation check when you’re on site.
Our Cheshire collimator is designed to be used with your telescope in a 1.25 inch focuser.
