I think it's fair to say that once you have Naglers, they are for life, as nothing else can beat them.

Why did I ever sell my 31mm Nag???    You just can't fault Televue stuff.

Thanks Felix. I came across that review a long time ago, before I bought my 31mm, but see it has been updated. TV stuff is an awful lot of money but it always provides that WOW factor and TV eyepieces help you get the very best out of your scope.

With regards to T.V ep's, what is the difference between the types?

 

To any body who is interested, I found the answer to my own question......

 

Why Are There 3 Types of Naglers?

To achieve the full magnification range over 82° apparent field

of view requires two types: Nagler Type-5 with focal lengths of 31, 26, 20, 16mm and Nagler Type-6 with focal lengths of 13, 11, 9, 7, 5, 3.5, 2.5mm.

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.
