 TeleVue Nagler 31.0mm eyepieces Type 5 EN5-31 provide unique 6-element design with four exotic glasses,
maintaining the contrast advancement of the
TeleVue Type 4 eyepieces while achieving a
true field area 82% larger than the
TeleVue Nagler 22.0mm Type 4.
Owners of fast Dobsonian/Newtonians
can enjoy a larger true field, free of secondary shadowing, than ever before.
For example, a 12.5", f/4.5 scope with a
TeleVue Paracorr will deliver a 1.5 degree field
(3 Moon diameters), at 53x with a 6mm exit pupil.
