The genuine Eyeopener from Peterson Engineering Corporation
enhances the performance of long focal length 2" eyepieces,
increasing the field of view while reducing vignetting. Depending
upon the specific 2" eyepiece, an EyeOpener will increase the
total amount of light delivered to your eye by as much as 65%,
the equivalent of a 2" or more increase in telescope aperture!

The compact length of the Eyeopener also locates your eyepiece
closer to the prime focus of the SCT, reducing aberations.

This fine tolerance black-anodized machined aluminum back screws
onto the telescope backplate and accepts a 2" diagonal or direct
mounting of 2" eyepieces, retained with three nylon screws.
Sell for $85.00 pluse $5.00 shipping. Pay by money order or (PayPal +3%) Thanks - Ron
