WILLIAM OPTICS 8-24mm Zoom Eyepiece - 1.25 fitting Price: £129.99 (Including VAT at 17.5%)
This new version has stops at 8mm, 12mm, 16mm and 24mm to make a zoom eyepiece practical for the first time when using pairs in a binocular viewer.
For example, using the Tele Vue Bino Vue with built-in 2x amplifier/corrector in a Tele Vue-85, the magnification stops are at 50x, 75x, 100x, and 150x.
Same field, eye relief, and continuous range as standard Tele Vue Zoom. Also Dioptrx ready.
With click-stops at 2, 2.5, 3, 3.5 & 4mm, this is the ultimate tool for tweaking out the last bit of power that the atmosphere will permit.
The 2-4mm Nagler Zoom is recommended for fast, high performance scopes of 800mm focal length or shorter, such as the NEW Tele Vue-60.
Just like its award winning 3-6mm Nagler™ Zoom brother, this Zoom has:
THERE HAVE BEEN ZOOM EYEPIECES IN THE PAST, BUT NONE QUITE LIKE THE TELE VUE 3mm-6mm NAGLER ZOOM. Since the time of Galileo, short-focal-length (hence high-magnification) eyepieces have been notoriously difficult to look through. That has changed in recent years, especially with the introduction of Tele Vue's line of Radian eyepieces. This Tele Vue zoom is small, lightweight, and offers the same magnifications (with click-stop settings) as four Radians while maintaining a constant focus and 50 degree apparent field.
It also lets observers choose in-between focal lengths, thus giving them the ability to tune the magnification to atmospheric conditions, which is very critical for high-power viewing. Although the zoom's 10-millimeter eye relief isn't long enough for eyeglass wearers, it is enough to make this a very comfortable eyepiece to look through.
