TeleVue Nagler Type 5 31mm
This eyepiece is in a class by itself. I have used it in many different sizes and types of telescopes. The result is always the same, WOW!, what a view!!! The only problem is balancing the scope and it is worth the trouble.

TeleVue Nagler Type 5 31mm
Superb eyepiece. Incredible FOV and contrast. Offers 3D view compared to 35 mm Panoptic which looks only 2 dimensional. If you can afford it, buy it!

TeleVue Nagler Type 5 31mm
I spent a long time before I finally bought one. I ran with a 27 Pan and thought the notion of spending over $600 on an EP was absurd. The Winter of 01-02 has had such poor seeing that I've explored wide-field more than I ever had. More and more views through other's 31's, and the non-stop accolades, made it so that I could no longer deny it. I sold my 27 Pan AND my Paracorr to fund the 31. I came out ahead.

The field correction is so incredible, even in my f/4.5, that I feel no need to get the visual Paracorr as I had initially planned for. I wholeheartedly agree with the estimates of the 5% edge of field distortion. Considering the true field, what it takes to see the edge of the field, and even the level of distortion itself at the edge, make this EP a marvel. I've got the 31T5 and the 17T4 and won't be getting that visual Paracorr after all.

Another issue I agree with is the level of color. Anyone who feels this 6 element design somehow compromises light throughput needs to take a look. The amount of detail and level of color I've seen in the past month has been nothing short of phenomenal. M42 now shows the usual light green but is now accompanied by a bright green and some pink tints. Stars show their true colors much more vividly than ever before as well. All this with the same scope at the same site(w/ or w/o the old Paracorr and the 27 Pan by comparison). I felt verifed in this observation when a friend brought his scope over and kept saying, "I'd never seen that before!" He uses a 22 Pan almost exclusively. We ended up using whichever scope had the Nagler in it despite having my 15" and his 17.5" just yards apart.

The 31 had the same affect just the weekend before at a club observing session. The weather was blustery so only about 10 people showed up. After an hour or two, the line was behind my scope. The showstopper was the Nagler. Most would get their view then walk right back to end of the line again. The scope that night was a 180mm Mak-Newt. I acquired it for use as a high mag specialist. At f/6 with the 31 in the focuser, it's a wide-field dream machine. The view of the Perseus double cluster was the best I and those that commented had ever seen. Bright, tiny little pinpoints of light in a wide variety of colors against a pitch black background; it was mesmorizing. I usually get the "WOW!" remark from school kids looking at Saturn, not from seasoned observers looking at a familiar deep-sky object.

Have a yard sale, check the car and the couch for change, sell off every EP in the 24mm-55mm range, get a night job, mortgage the house....whatever it takes.
Just get one!

TeleVue Nagler Type 5 31mm
The king of kings!!! The views through this thin in my 16" F4 dob with a Parracor Type 2 are just sick. M31, M105 & M32 in the same FOV with sharp to the edge stars, yes, yes yes. The Double Cluster, M46, the entire Orion sword, and so on. Just a marvelous eyepiece, as good today as when it first came out. An excellent companion to the 21mm Ethos. Pure bliss : )

TeleVue Nagler Type 5 31mm
In a 20" F/5 Obsession there is no better low power widefield ep than this one.What a view .The Veil,Rossette,North America and many open clusters are fabulous in this ep.I sold my 35mm pan in order to buy this and have no regrets.The field seems much flatter with this ep than with the 35mm Pan.The Pan was a great ep but this ep like the Beatles is fabulous.

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.

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.

TeleVue Nagler Type 5 31mm
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.
