Howie Glatter Square Grid Holographic Attachment

Howie Glatter's Square Grid Projection Attachment. A wide pattern spanning 21 degrees, best for fast scopes down to f/2.7 With this attachment a 10 x 10 line square grid pattern is supplied as standard unless otherwise requested because it is the widest pattern. It spreads 21 degrees which allows centering of optics as fast as f/ 2.7. This pattern is recommended for general use because it can be used with the fastest telescopes likely to be encountered.
