Please Note:
- This is the new "NV" version and not the old version.
- New Version (this item): Bigger & coarser 3/8-32 thread diameter. Identified by a visible ring. Old Version (no longer available from Agena): Super fine 5/16-56 thread diameter. No visible ring
- If you plan to use one of their holographic attachments such as this item, you need to make sure that you match the "old" Howie Glatter collimator with the "old" holographic attachment, and the "NV" collimator with the "NV" holographic attachment.
Optional holographic attachments for Howie Glatter laser collimators screw into the laser aperture and have a white screen front surface. They contain an optical element that diffracts most of the laser light into a diverging symmetrical pattern around the central beam. The projected pattern is useful for centering optical elements by making it symmetrical with the edge of the optic.
A 10 x 10 line square grid pattern is supplied as standard 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.
This item is meant for use ONLY with compatible Howie Glatter laser collimators. It cannot be used with collimators from any other brand.
