Tele Vue EN6-03.5 3.5mm 1.25-Inch Nagler Apparent Field Eyepieces

Blackened lens edges, anti-reflection threads and rubber eyeguards deliver maximum contrast. 100% full field visual inspection on our Televue's own flat-field test instruments guarantees the performance of every Tele Vue eyepiece. A compact 7-element design using different exotic materials plus coating processes. Untouched is the full field pinpoint sharpness, but this series benefits from greater contrast. High technology, parfocal 1 1/4" eyepiece, with 12mm eye relief. The 3.5mm Nagler Type 6 is a natural progression of 1.4x power steps from 7mm and 5mm Naglers. You don't have to sacrifice field in order to gain sharpness and power. And, you're not limited to slow scopes, or have to squint through pinhead lenses. These are the lunar and "planetary" eyepieces with field to spare.
