Abstract
This invention describes an apparatus and method for generating artificial stars for the simple collimation of catoptric, dioptric, and catadioptric telescopes using a light source along with an appropriate hologram and housing to generate collimated laser beams that enter the front aperture of the telescope. The apparatus of this invention can be fastened to the outside of the telescope aperture. In addition, this invention allows the apparatus position to be adjusted at its tip and tilt axis to center an artificial star under the view of the ocular. The light source illuminates the hologram from some off axis position. Once the hologram is illuminated, the collimated beam emanates from the hologram with a slightly different angle. When these beams are then viewed with the telescope they appear as artificial stars.
