Hi.

This is the 532nm version of Howie Glatter's green holographic laser collimator which includes a removable 9x9 square grid from the front of the laser. This offers 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. Battery included. It fits both 1.25" and 2" apertures.

I am also selling this with an Orion 2" to 1.25" Precision Centering adapter (never used). This ensures the laser is centered up in your drawtube.

You will be hard pressed to buy this in Australia I believe as I cant find one online. I have successfully used it to collimate an RC and check collimation on other instruments.

$650 for the pair, excludes shipping.

cheers
Martin
