Sky-Watcher 4 mm Nirvana-ES UWA 82° Eyepiece

Sky-Watcher 4 mm Nirvana-ES: 82 degree sky, high magnification

The Nirvana-ES series brings the ultra-wide 82-degree field of view to an accessible price. Seven lens elements in four groups with broadband multi-coating deliver a sharp, high-contrast image all the way to the edge. With the large field of view, you don't just look at an image; you look into it: stars appear and disappear at the edge of your field of vision.

In calm air, this is the eyepiece for lunar detail, planetary discs, and close double stars. The wide field keeps the object in view longer, even on a manually operated Dobson.

Features

• 82 degrees apparent field of view

Compatibility
