Product Description:

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. 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).

Package Include:

1 x Collimating Eyepiece

Please Note:

Regarding the bending of the cross wire, if you receive a curved cross wire, please take out the front ring, then straighten the cross wire, and then restore the structure. Thank you for understanding.

Light shooting and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.

Fits in 1.25" focusers and easy to use;simply cap the telescope, remove the diagonal, and place the eyepiece directly in the focuser.
For aligning optics of Newtonian reflectors, Dobsonian reflectors, and Schmidt-Cassegrain Telescopes (SCTs).
The short collimator for mirror (reflector) telescopes has a 45 degree plate for easier visual accuracy.
Item was made by aluminum with crosshair at the bottom allow quick and precise centering of the optics.
This collimation eyepiece can be used for precisely collimating the Newtonian and Schmidt-Cassegrain reflector telescopes for better image quality.
