Sky-Watcher 7 mm Nirvana-ES: 82 degree sky, planets and compact deep-sky
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.
Planets, the lunar terminator, and bright globular clusters come to life at this magnification, with enough field around them for comfortable tracking.
Features
- 82 degrees apparent field of view
- 7 elements in 4 groups, broadband multi-coating
- 12 mm eye relief with foldable eyecup
- 1.25 inch vatting met filterdraad
Compatibility
Fits in any 1.25 inch focuser or diagonal. On manual Dobsons, the wide field is extra valuable: objects stay in view longer between two nudges.
