Concept: You may know there’s a long history of naming eyepieces after their designers:
Kellner, Erfle and Plossl, to name a few. In the late 70’s I designed an eyepiece sufficiently
radical that I dared attach my name to it. Even today, I must admit a little discomfort when
talking about ”Nagler” eyepieces.
With ”Naglers”, my aim is to approach the wide angle perspective of naked eye vision, while
maintaining the highest degree of sharpness, contrast, and viewing comfort. The goal is to allow
the telescope to virtually ”disappear,” leaving the impact of ”spacewalk” viewing. -Al
NaglerNagler Type 4
Applying the experience of the Radian development to the 82° Nagler series, yielded more
contrast, reduced pincushion, more true field, longer eye-relief, and fewer elements to achieve
focal lengths of 12mm, 17mm and 22mm. With added eye-relief, the click-stop Instadjust eyeguard
helps maintain proper eye distance and centration.
For deep sky viewing, the comfort, clarity and contrast gets us closer to our ”spacewalk” viewing
goal.
Nagler Type 5
With the 31mm, the unique 6-element design using four exotic glasses, maintains the contrast
advancement of the Type 4s while achieving a true field area 82% larger than the 22mm 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 Paracorr will deliver a 1.5 degree
field (3 Moon diameters), at 53x with a 6mm exit pupil. Use our eyepiece calculator to figure out
what the 31mm will deliver on your scope.
Nagler Type 6
The 7-element, Nagler Type 6 design is based on the original patented Nagler design. This new
7-element design update for the short focal length Nagler deserves its own designation. Using
different exotic materials, coating processes and design ingenuity, Al has massaged more
eye-relief, contrast, and true field of view into the shorter focal length Naglers, while
maintaining the absolute sharpness of the originals. Eye-relief is 12mm on each model, and all
are sized about the same as the original 7mm! Weight about 0.4 to 0.5 lbs. Available in 13mm,
11mm, 9mm, 7mm, 5mm, 3.5, and 2.5mm focal lengths.
