Description

To get the most out of your Newton spotting scope, you really need to align or collimatise the mirrors. It may take some time to get used to aligning both the secondary and primary mirror, and this short collimator can make it much easier. The short collimator for mirror telescopes features a 45 degree plate for easier visual accuracy. Collimation is the alignment of the elements in 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 optimal focus at the point from which the image is viewed (eyepiece or possibly a camera)
