This is a combination sight tube and Cheshire eyepiece, consisting of a 5"-long tube made of black-anodized aluminum. It fits in a 1.25" eyepiece holder. A peephole in the top and wire crosshairs at the bottom enable precise centering of Newtonian optical components. The polished 45° internal surface projects an annulus of light into the optical path to facilitate primary mirror alignment. Simply insert the Collimating Eyepiece in the focuser drawtube and follow normal collimation steps.

Orion, and Celestron which has a similar product, sells this collimation device for $39.95 plus shipping.

My price is $30 which includes shipping to the continental US. You'll save about $15 over their price.

Thanks for looking,

Jim Dixon
