Taking performance inspiration from the venerable Nagler series, then combining the optical design properties of both an eyepiece and Barlow, the Tele Vue Panoptic 41mm Wide Angle Eyepiece has a 6-element/4-group lens configuration that produces a generous 68° field of view and improved edge-of-field performance, while minimizing size and weight.
This eyepiece has the longest focal length in the series, and one of the longest that Tele Vue offers, to produce a low magnification on most optical tube assemblies (OTAs) — making it ideal for wide-field observations of the night sky and most lunar, planetary, and deep-space needs. It is outfitted with fully multi-coated optics to maximize light transmission, color rendition, and contrast, with blackened lens elements that limit internal light loss and diffraction. It also has a fold-down rubber eyecup that helps to block stray peripheral light, avoiding interference with the views and further enhancing contrast. Its exceptional 27mm eye relief provides ample room between the lens and eye to prevent accidental contact that can interfere with views. This model has a large 2" barrel diameter to make it even more comfortable to view through, and a textured rubberized grip for sure handling. This eyepiece is parfocal with the 27mm Panoptic eyepiece, requiring little or no refocusing when changing between the two.
