Housed in a 2" barrel like the 35mm, the 27mm is lighter & smaller. It's perfect for any telescope size, type or speed, where a little more magnification is desired, yet still allows full field viewing with eyeglasses. For example, with the Tele Vue-85, it gives 22x and a true field of 2.9 degrees!
The Televue Wide-Field design was the starting point for the design of the Panoptic. A lens interface between the eyepiece and Barlow lens was added as a way to keep size, weight, and cost to a minimum while improving edge of field performance even further.

- filter threads
- rubber grip rings
- cover for the eyeguard
- an undercut in the barrel for extra locking security
