Tele Vue Barlows: "An Optically Perfect Window " Properly designed Barlows do wonderful things. First, they amplify power while retaining the eyepiece's eye-relief. Second, they slow the telescope's f/#, which improves eyepiece sharpness. Third, the designer can introduce compensations for eyepiece aberrations. The 4X Powermate Barlow is a 4-element parfocal, compact amplifying lens system. POWERMATE consists of a negative achromatic doublet plus a positive "pupil- correcting" doublet. While it looks and functions like a Barlow, your eyepiece will operate with pupil locations where the designer intended, avoiding mismatch problems. POEWRMATE optimally mates its power to your eyepieces. No additional "interface lens" is needed, since POWERMATES have it built-in. In addition to full... Less

This model is nearly parfocal (unlike the Big Barlow / Interface combination), so it can be effectively used in our 2" diagonals. Its performance is excellent with every 1¼" or 2" eyepiece we make (yes, even the 31 Nagler Type 5!). Both the 2" eyepiece holder and the special 2"-1¼" low-profile adapter use brass clamp rings for secure, non-marring operation. And it also has a very unique feature: you can unscrew the 2" eyepiece housing and screw on a special T-ring adapter for solid, compact attachment of CCD or camera equipment.

1.25" Barlows Offered in 2x and 3x magnifications, these 1.25" Barlows perform identically. Simply choose either or both based on your eyepiece collection. Features include parfocal- ization, 1.25" filter threads, captive lock screws that won't fall out and full multicoatings. 2" Big Barlow Offered in a 2x magnification, the Big Barlow is ideal for Newtonian scope owners. It will be parfocal with both 2" and 1.25" eyepieces in this application. Features include threads for 48mm filters, captive lock screw and full multi-coatings. Note: The Big Barlow is not recommended for use with 2" diagonals because it's length prevents it from being parfocal. With some telescopes, focus might not be reached, particularly when the interface lens is also used with it. A far better approach with no... Less

Note that these eyepieces have shorter eye relief than others recommended for DIOPTRX, so to minimize any vignetting, it's best to use these for deep-sky applications w

Instadjust was developed for maximizing contrast while aiding in proper eye positioning for non-eyeglass wearers. It is essential, since with the Radian's long eye-relief, non-eyeglass wearers could easily get too close to the eyepiece, resulting in vignetting where edge field rays miss your pupil. The push-pull, click-stop adjustment permits fast positioning and maximum suppression of environmental stray light. Another unique development is the Pupil Guide. It helps non-eyeglass wearers, especially novices, zero-in and stay centered on the exit pupil. The Pupil Guide is included with all Radian and Nagler Type 4s and fits under the soft, fold-down rubber eyeguard. SpecificationsRad ian- 20mm eye-relief across the entire series.

Introducing the Televue 6mm Delos Eyepiece. The latest from Televue the 6mm Delos Eyepiece was a hit at NEAF 2011. According to David Nagler of Televue the Delos project started in 2008. The goal was to build an eyepiece that retained many of the same optical features as the the wildly successful 100 degree Televue Ethos eyepiece line within a 72 degree field.By reducing the field to 72 degrees it allowed the engineers over at Televue to offer more eye relief, 20mm to be exact. Every optical, mechanical and ergonomic aspect of this eyepiece was carefully thought out in order to maintain the classic Televue excellence we have come to rely on.New to the Televue Delos is the adjustable eye guard that locks into position. This enhances contrast by preventing stray light from entering the... Less
