TeleVue - PANOPTIC-BARLOW INTERFACE

You can double the power of any eyepiece with the 2x Big Barlow, but adding the interface lens brings the pupil back to original
position when used with long focal length eyepieces such as the Panoptic 41, 35, or 27mm 2" models. The combination of interface
and Big Barlow mimics the Powermate concept

Of course, multi-coatings, blackened lens edges, filter threads, rubber grip rings and exemplary construction are standard on all
Panoptics. Little niceties such as a cover for the eyeguard, and an undercut in the barrel for extra locking security complete the
package. A double identifying ring distinguishes all Panoptics in your eyepiece case.
