Many of the best eyepieces in the world carry the name of Tele Vue, including the Tele Vue Nagler eyepieces, Tele Vue Panoptic eyepieces, Tele Vue Radian eyepieces, Tele Vue Plossl eyepieces, and of course, the Ethos line, with their amazing 100° field of view. Tele Vue also produces the finest Barlows and Powermates.

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.
