Tele Vue Nagler Eyepieses
Now you can have eyepieces that give you a staggering 82 degree wide apparent field of view with outstanding sharpness and exceptionally comfortable eye relief for eyepieces of very short focal length!
Why Are There 3 Types of Naglers?
The Type-5 permits the largest true field possible (31mm has 42mm field stop), while the shorter focal length Type-6 models are parfocal, with similiar size and weight and all with a comfortable 12mm eye relief.
The Type-4 models feature about 18mm of eye relief and with the "instajust" eyeguard are best for eyeglass wearers or Dioptrx users in their 22, 17, 12mm focal length range.
Type 4 Nagler Eyepieces.
Type 5 Nagler Eyepieces.
The new 6mm Nagler is smaller and lighter than the older type 2 - the new 6 element design replacing the previous 8 elements. Tele Vue say "This exciting new eyepiece looks like the 19mm Panoptic but packs the visual impact and sharpness we all expect from the 82 degree Nagler series".
26mm Nagler Type 5: This is a somewhat smaller, lighter and more powerful version of the celebrated 31 Nagler Type 5. It weighs about 1.6 lbs and has a field stop diameter of 35mm. It is parfocal with the 17mm Nagler Type 4, making it a nice match in size, weight and convenience.
The 20mm Type 5 is a compact 1-pound, 2" eyepiece that fills out the eyepiece line and is a worthy successor to the heaviest commercial eyepiece ever produced: the Nagler 20mm Type 2, which weighed-in at 2.3lb. when introduced in 1986.
Type 6 Nagler Eyepieces.
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.
These amazing eyepieces are available in 13mm, 11mm, 9mm, 7mm, 5mm, 3.5mm, and 2.5mm focal lengths.
The 11mm Nagler Type 6 slots in perfectly between the 13mm and 9mm Type 6s and makes a perfect companion to the 7mm.
The 3.5mm Nagler Type 6 is a natural progression of 1.4x power steps from 7mm and 5mm Naglers. The 2.5 is also a 1.4x step from the 3.5mm. You don't have to sacrifice field in order to gain sharpness and power.
And, you're not limited to slow scopes, or have to squint through pinhead lenses.
These are the lunar and "planetary" eyepieces with field to spare.
