TeleVue Eyepiece Nagler Typ 7 5.5 mm 82° (85579)

TeleVue Nagler Type 7 5.5 mm 82° Eyepiece (Model 85579)

TeleVue is dedicated to producing premium eyepieces for a wide range of astronomical applications. The Nagler and Ethos series were developed to deliver exceptional deep-sky performance, especially in fast Newtonian telescopes. The Nagler line has long been regarded as a benchmark for wide-field viewing, combining immersive fields of view with outstanding edge correction.

The Nagler Type 7 5.5 mm features an 82° apparent field of view, providing a spacious and engaging observing experience. Its advanced optical design ensures sharp stars across the entire field, even in fast optical systems. This makes it particularly comfortable to use with Dobsonian telescopes, as the wide field allows objects to remain visible longer before manual adjustments are needed. The 5.5 mm focal length is well suited for high-magnification observations of planets, the Moon, and compact deep-sky objects.
