A very large field of view, a real "space walk experience" for deep sky lovers. Looking through the Explore Scientific 100° Series binoculars, you can almost feel like you're among the stars. In particular, thanks to their flat field of view, stars remain point-like at the edges, so this eyepiece can be confidently recommended to owners of brighter binoculars.
An additional advantage of the ultra-wide field of view is that the object remains in the field of view for much longer, a significant convenience for those observing with a watchless telescope (e.g. Dobsonian). The extremely wide field of view makes it easy to rotate your eyes around. This observation technique, known as inverted vision, greatly aids the observation of faint celestial objects.
A unique feature of the eyepieces is the waterproof construction, which makes the internal parts particularly resistant to condensation. The effective anti-reflection coatings on the lens surfaces (fully-multicoated) and the matt black paint on the inner surfaces guarantee outstanding contrast and anti-reflection protection.
The eyepieces fit into a 2" focuser.
