Howie Glatter Laser Concentric Circle Holographic Attachment


This Howie Glatter holographic attachment has a nine-concentric circle pattern that covers 10 degrees and is approved for telescopes with a focal ratio of f/5.7 or higher. This pattern is specifically beneficial for Cassegrain telescopes where the effect of the pattern is sometimes seen on the mirror exteriors because the light from the laser is extended over less of an area and is therefore brighter than the standard square grid pattern. A brighter pattern is more advantageous due to the fact that the projected pattern can only be seen by dispersed light from dust, dirt, or optical coarseness, particularly if the mirrors are free from blemishes.
