OCULIMATION COLLIMATOR GLASSES TELESCOPIC EYEPIECE CHESHIRE EYEPIECE OPTICAL GLASSES Collimation Eyepiece The short collimator do of mirror (reflector) telescopes has a 45-degree plate for greater visual accuracy. Fits do 1,25 inch eyepiece lifts and is easy to use. Simply cover the telescope, remove the diagonal, and place the eyepiece directly in the eyepiece lift. Element is made of aluminum alloy, and the cross at the bottom allows quick and precise centering of the optics. This collimation eyepiece can be used do precise collimation of Newton and Schmidt-Cassegrain mirror telescopes for better image quality. Do setting the optics of Newton's headlights and Schmidt-Cassegrain telescopes. LIST OF PACKAGES 1 x Collimation Eyepiece COLLIMATOR GLASSES Collimation is the process of fine-tuning the optical axis of optical elements with the mechanical axis. It can do this work so that the light of the telescope creates clear images in the center of the eyepiece. A collimation eyepiece is more accurate than a simple collimation tool.
