'Uncle Al's hand grenade.'
This eyepiece earned this affectionate nickname not only due to its form but also due to its pin sharp optics. This 31’ Nagler is the best eyepiece in its class.
Ambitiously, Telvue has built the best possible eyepieces for any purpose. This is why they have released different versions. Nagler and Ethos are optimised for glasses-free deep sky observation on fast-aperture Newtonian systems.
Nagler eyepieces are classics with an 82 degree visual field and exceptional edge correction. The eyepieces are particulary comfortable to use on Dobsonian telescopes. Thanks to the large visual field, tracking does not have to be readjusted so often.
