TeleVue Nagler Type 5 31mm
I just purchased the eyepiece after saying that I would positively not purchase one. The field of view is noticablly larger than the 35mm Panoptic with better contrast and virtually no pincusion distortion. Absolutely stunning views through any of my telescopes (I have three of them a 6" f/12 (mak/cass), a 5" f/6 (mak/newt), and a 4" f/5 (refractor). Worth every penney of its $595 asking price!

Huge, heavy, and expensive but... we put this behemoth on a Televue 5.5" and Orion was the most beautiful I had ever seen it. Stars were sharp everywhere. Contrast and transmission were perfect. Size of field added tangible sense of drama. Thought this EP was just a gimmick until that moment. It's as good as they say.

Outstanding. - None of the kidney bean effect that plages the 12mm type 4 for example. you don't have to be an eye placement expert to use this eyepiece - Sharp to the 82 degree edge!

Looking through the 31MM Nagler 5 is like looking into a crystal clear pool of water. You know the water is there, you just can't see it and everything is crisp, clean, and clear. This wide angle is awesome.

The TeleView 31 Nagler Type 5 eyepiece is worth every bit of the price it cost. My most brilliant eyepiece. The 82 degree field has pinpoint stars across the total field of view, lacks chromic aberations (false coloring), & lacks beaning effect at edges. The view is like looking into a crystal ball (mesmerizing!). My scope happens to be the Vixen (made for orion) 102mm ED-GP refractor.

AWESOME! Yeah its big and heavy, but the views are truly incredible. Compared side to side to 35mm Panoptic...result? I put the panoptic up for sale the as soon as I got home. The Nagler provided far more contrast and noticibly brighter images.

Extroidinary! I've enjoyed a 35mm Panoptic for several years, but it suffers greatly by comparison to the Nagler 31. The 31mm has more comfortable eye relief, better contrast, sharper star images (yep, all the way to the edge, with a 20" f/5 Newtonian) and more accessable eye relief. And, as big as it looks, the 31mm Nagler is approximately the same weight as the 35mm Panoptic so my scope doesn't need more counterweights than it already has...

Only quibble - noticable vignetting at the edge when examining the entire fov. Otherwise, the 31mm Nagler is wonderful and a joy to observe with.

TeleVue Nagler Type 5 31mm
Just purchased. Words can't describe the view. All stars are pinpoint to the edge. It also has a total flat field across the whole panoramic view.I used the 31 TY5 in my 6" home built reflector. Images are almost as bright as my Meade 10" Dob. Well my 6" does have enhansed coatings on both mirrors. The 31 Ty5 may cost alot but it is well worth the money. The panoramic view is heavenly. It is the BEST eyepiece on the market today.

It may be a huge chunk of change but it is a huge eyepiece. And well worth every dollar. The view is super! It doesn't get any better than this. The 31 Ty5 is the best eyepiece on the market. No distortion, no pincushion, no kidney bean effect, no coma ( in a 6" reflector ). The eyepiece gives a total flat field across the whole panoramic view with bright images. Now compliment this eyepiece with a lumicon OXYGEN 3 filter and watch the results.

A crowning achievment for TeleVue. The widest sharpest field available today for less than half the price of a Leitz 30.

TeleVue Nagler Type 5 31mm
Well, this eyepiece prompted me into a highly emotional decision, buying it. I had planned on buying something else but bought this instead. I got to compare it directly to the Leitz 30mm. In reality, it's too close to call. One annoying aspect with the Leitz is that it blacks out very sharply if you move your eye off axis too much. When you do this on a 31mm Nagler, it just fades out and doesn't seem to do so at nearly as narrow an angle from center. The Nagler 31mm takes a LOT of in travel on the focuser. I had to grind 1/4" off of my Dob's truss tubes and jack my mirror almost all of the way up. The Nagler gave nothing away on axis as I've read in other reviews, it's a dead heat. The Nagler was sharper on edge for sure. The eyepiece in a 14.5" dob at f4.5 more than encompasses the big section of the North American Nebula except for the top of Canada and edge of California so to speak. The eyepiece most notably makes it much, much easier to find objects. Mine was used for much of the evening in a C14 Celestron. It barlow EXTREMELY well in my 2X Pocono Mt. Deluxe barlow, perfectly framing the Swan Nebula. If you own a C14, this is a must have eyepiece. The barlow/31 Nagler is undoubtably a very expensive but very, very nice 15.5mm eyepiece! In the aforementioned Dob, the Andromeda Galaxy takes on a whole new look. How often do you see two dark lanes with the companion Galaxy alongside for the ride? I rate the Nagler 31mm slightly better than the Leitz, especially considering the price. The Leitz is extremely nice but it would seem that the physics of the 70mm lens of the Nagler does a better job at edge correction. WORD OF WARNING: DO NOT LEAVE YOUR DOB UNATTENDED WITH THIS EYEPIECE IN IT!!! It will fall unless perfectly balanced.

TeleVue Nagler Type 5 31mm
This is a well made widefield eyepiece for deepsky observation, with simular specification with Leitz 30 but at half the price. The contrast between the star image compare to the deepsky background is a little less than the Leitz, but the object looks sharp and clear from center till edge. It is comfortable for long time viewing when you always want to resolve star patent in the globular cluster.

TeleVue Nagler Type 5 31mm
I saw this eyepiece in an ad and new I had to have one. I have been using my Meade 32mm SWA. The day it came in, it was around lunch time but I grabed it and put it in my scope and looked in. The first thing I saw was false color at the outer 20% of the field. If you guys who own one look at day with it you will see this orange band around the field. Also at night planets moved to the edge turn orange, it's not just a daytime problem. The field of view was impressive and pretty sharp to the edge. The edge is a little softer than the center. I also had very bad beaning effect, much worse than any of my other eyepieces. I loved the eyepiece, the contrast, the FOV but I could not stand the beaning and the orange color around 20% or more of the edge. I hated to, but I returned mine. I will try the Televue 22mm Type 4 and report on it. Al Nagler said it didn't have any of the problems I spoke of in the 31mm. Also, mine may of had a problem. If any of you guys who own a 31mm Type 5 would try it in the day and let me know how it works, I would love to hear from you. I might have to purchase another and try again. As far as a comfortable view the Meade 32mm SWA I have has the easiest view I seen. It very soft at the field edge but very sharp in the center. There is no false color of any kind in the Meade and you can not move your head to any position that causes beaning.

Just great in my 6 inch f8 Astrophysics and teleview Genisis SDF.Just completed a Messier Marathon with an 18 inch f4.5 "Obsessio" never took the eyepiece out from dusk till dawn....M42 looks unbelievable with the Nagler and an O-III filter.

TeleVue Nagler Type 5 31mm
I bought one new for a TV 102 and returned it the next day for a 35mm Panoptic. The 31mm Nagler has a hugh orange/red ring around its perimeter view that destroys it for terrestial viewing and can make a mess of planetary viewing as well. It is not sharp to the edges because of this large red/orange band at its perifery. The 31mm is a work in progress. When Al gets this ring around the collar problem straightened out, the present 31s will be obseleted and rendered into boat anchors. I did not want to go there because of its price.
