What is collimation?
February 20, 2005
Collimation is the proper alignment of the optical elements in a telescope, which is critical for achieving optimum results. Poor collimation will result in optical aberrations and distorted images. Not only is the alignment of the optical elements important, but even more crucial is the alignment of the optics with the mechanical tube: this is called opto/mechanical alignment.
