Televue 2mm - 4mm Nagler Click-Stop Zoom 1.25" Eyepiece

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.

With click-stops at 2, 2.5, 3, 3.5 and 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 Televue -60. Just like its award winning 3-6mm Nagler™ Zoom brother, this Zoom has 10mm of eye relief and a great 50º apparent field of view!

Sharp!!!
Sharp at any setting.
I compared my 4mmUO against the 4mm setting and found no optical difference, only more eye relief.
I compared to my 2.8mm Tak LE to a setting matching the 2.8mm and was hoping to see more detail on the fixed length eyepiece, but did not succeed on the purpose.
At high power the object remains in the fov, because there in minimal movement on changing the settings.
I use it on a Stellarvue 80mm apo f/6.125, it gives 122x-anything in between-245x.
At 245x gives great detail on doubles, moon and planets.
