The new series of the high-quality Helios ultra-wide angle telescope eyepieces allows jaw-dropping viewing experience. The eyepieces are an alternative to the expensive eyepieces of the so-called premium manufacturers, with comparable performance.
The large 82 degree apparent field of view, the excellent correction of the field over the entire field and good contrast allow, in combination, wonderful, intense and memorable viewing experience. It works superbly in telescopes of all focal lengths.
Due to their slim design and the comfortable, calm view, the Nirwana-ES eyepieces are well suited for binocular observing, for example with large binoculars which are designed for exchangeable 1.25" eyepieces, but also with binoviewers for telescopes.
Large eye lenses and a soft, adjustable rubber eyecup are the base for comfortable viewing. A sound multi-coating is a given in this class, of course.
