Chesire collimation eyepiece – the classical collimation tool for Newtonians and Refractors
Collimating your refractor is quick and easy when you use this 1.25″ Cheshire collimating eyepiece.
Refractor Collimation: To use this eyepiece, simply cap the telescope, remove the diagonal, and place the eyepiece directly in the focuser. Use natural daylight or shine a flashlight into the side opening with the 45-deg angled silver plate. Look into the small opening at the top of the eyepiece. You will see one or more small faint circles (usually overlapping) near the center. Adjust the objective cell’s push-pull bolts until the small circles merge into one. Thats it! With precise collimation, your refractor telescope will deliver the best image it can. Newtonian Collimation: At Newtonian telescopes, the reflected images of main- and secondary mirror must be exactly concentric. Due to the centric viewing position, this can be achieved without errors.
Great for quick and precise alignment of your Newtonian reflector telescope, to get the most out of your Newtonian scope you really need to align or collimate the mirrors
It can take some time getting used to aligning both the secondary and primary mirrors and this short collimator can make it much easier
The short collimator for mirror (reflector) telescopes has a 45 degree plate for easier visual accuracy
Colimating 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 eyepiece or possibly a camera)

Make your seeing experiance much better with this simple tool! Quickly and precisely align your Newtonian reflector telescope!
Stars don’t come to a pin point focus. Planets looks slightly hazy. Sometimes optics yield images that are less then perfect. To prevent this from happening, you’d better collimate your Newtonian telescope with a collimator.
The 1.25″ collimator is an excellent accessory. It can take some time getting used to aligning both the secondary and primary mirrors and this short collimator can make it much easier. The short 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. Colimating 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 eyepiece or possibly a camera).
