Nagler Zoom 2mm—4mm Eyepieces

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:

• Eye-Relief: 10mm

• Apparent Field-of-View: 50º!

Nagler Zoom 3mm—6mm Eyepieces

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 (a 1999 Hot Product). The new 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.
