Ultra-wide angle for impressive images
The Sky-Watcher 7 mm Nirvana-ES eyepiece gives you a huge 82° field of view. You will see stars, nebulae and planets with a sharp and clear image all the way to the edges. Perfect for all focal lengths, so you can flexibly switch between objects.
Comfortable viewing, long sessions
Seven lenses in four groups provide razor-sharp contrast and minimal distortion. The large eye lens and soft, swivel eyecup make long observations comfortable. The 12 mm eye relief keeps your eyes relaxed, even during longer sessions.
Sturdy and easy to use
The lens edges are blackened and internal apertures minimize reflections. The eyepiece is parfocal, keeping it sharp when changing objects. The aluminum body with rubber grips feels solid and comfortable. You can use standard 1.25″ filters thanks to the thread.
