Lunt 7–21mm Zoom Eyepiece

Description

The Lunt 7-21mm Zoom Eyepiece is a variable-focal-length eyepiece that lets you adjust magnification anywhere from 7mm to 21mm without swapping eyepieces. That's handy for solar observing in particular — start wide to take in the full solar disk, then zoom in for close-up detail on a single sunspot group or prominence, all with one eyepiece. Like the rest of Lunt's fixed-focal-length eyepieces (8mm through 27mm), it uses a standard 1.25-inch barrel compatible with Lunt's solar telescopes and other standard 1.25-inch focusers.
