Product Description

This latest premium 1.25" eyepiece from Al Nagler uses seven optical elements for optimized performance across a very wide 82° field of view. Its wide field makes observing feel like you're looking through a "picture window on space" rather than through an eyepiece. Several different extra low dispersion glass types and specialized coatings are employed for improved contrast and longer eye relief than previous Nagler designs, even those acclaimed as being among the finest wide field eyepieces available. Amazingly enough, despite the optical improvements, this new 13mm Type 6 design is markedly smaller and lighter than the original 25 ounce 13mm Nagler it replaces.

At a usable eye relief of 12mm, the 9mm Nagler would normally vignette the field of view for eyeglass wearers. However, since the 82° field is so wide that you can't see the full field without having to move your head from side to side to take it all in anyway, vignetting in the conventional sense is not a problem.

The optical performance is typical TeleVue - well corrected and sharp from edge to edge. There is a slight loss of contrast when compared to an eyepiece with fewer elements, due to the additional lenses needed to achieve the unique combination of very short focal length and very wide field. The loss is minimal though, on a par with the contrast loss in an eyepiece/Barlow combination with the same effective focal length. In the eyes of many observers, however, the "picture window on space" observing experience of its exceptionally wide field more than makes up for any slight contrast loss.

Supplied plastic caps seal both ends of the eyepiece to keep it dust free. A rubber grip ring gives a secure and comfortable grip in all temperature extremes. A groove machined into the chrome barrel of the eyepiece acts as a safety stop to keep the eyepiece secure should the focuser thumbscrew loosen slightly while using the eyepiece.

I recently bought a TV 13mm Type 6 from Astronomics.
The sharpness, contrast, and 82 degree field of view are all phenomenal! Thanks to Al Nagler and Astronomics for a
Superb product!

This is my go-to high power eyepiece for my HD1100 SCT. It is very comfortable to view through, great contrast and with amazing clarity right to the edge of the field. (Posted on 9/9/2019)

Excellent product. The contrast and sharpness of the fov is amazing compared to other products of lesser quality at a lesser price. Comfortable to use and fair eye relief when wearing glasses. (Posted on 7/22/2019)

One of my all time favorite occulars. Works in all of my scopes equally well and also beautiful in design. A very good balance of eye relief, fov, sharpness and contrast. Go for it! (Posted on 1/14/2019)

Like others, there's a lot to like about such a wide, well-corrected FOV in such a compact package ... not least of which being I can use it freely without worrying about being asked how much I spent on it. ;)

The wide FOV also makes it easier (more forgiving) for my kids to view at higher magnifications. Very happy with this eyepiece. (Posted on 1/14/2019)

This eyepiece packs the excellent Nagler view into a very compact package. I am blown away most of the time when I look through this thing. The 82 degree field is huge, especially conserving how small the eyepiece is. Performance is excellent; I use this in an 80mm f/6 refractor and it is sharp across the entire field with no sign of false color. At 13mm focal length, this eyepiece strikes a good balance between magnification and exit pupil to produce images with great contrast. It is a great choice for general viewing in any scope, really.

Doesn't really have any weaknesses. Comfortable and easy on the eye. Nice light transmission, so works well on dim DSO's. Gives sharp, contrasty solar system views in my variety of different scopes. I really appreciate the small size and weight, which makes it hassle-free to use in a small grab-and-go setup (no need for rebalancing as with heavier EPs). One star off, only because I am not blown away by the view, as with an Ethos. I think this EP is a little pricey, but if you can get it used or on sale, go for it. Even at full retail, you won't regret it. I have other EPs in this FL range, and I have thought of selling my 13mm T6 Nagler, but I just never do... it's just too solid of a performer.

Nice eyepiece that provides great eye relief which is key. Good way to move up in magnification from a 26mm if you do not own already own a barlow (Posted on 11/3/2018)

I sold my original 13T6 Nagler and regretted it for a couple of years until I bought another one. I'll not be making that mistake again. Though I currently own 2 different 13mm 100 degree eyepieces including an Ethos this 13T6 will stay in my primary observing kit alongside the survivor of the testing between the other two. This 13mm T6 Nagler is one of the very finest eyepieces. You should probably have one. (Posted on 10/30/2018)

Sharp, wide, lightweight, reasonable eye relief, good contrast - the list goes on. I can't find any fault with this eyepiece. Along with the 11mm it's my favourite Nagler Type 6. Works great in all scopes whether a fast Newt or refractor. (Posted on 10/27/2018)

There are better eyepieces out there, but none offer better value in my opinion. For me, it's the Nagler line, and the 13mm is the crown jewel of the series. It features legendary Teleview quality, and it's not too light. It's beautifully crafted from high quality materials. It's got stellar optics not but it's not too heavy. It's delivers razor sharp images right to the edge of that superb 82° field of view. (Posted on 10/25/2018)
Review by:
This is my favorite mid-low power eyepiece to use in my refractors. 13mm is the lightest in this series, and provides fantastic wide field views. Eye relief is comfortable without glasses, as mentioned in another review. If I had to give up all my Type 6 eyepieces except one, this is the one I would keep. Nothing else comes close in this form factor. (Posted on 10/16/2018)

If you're looking at this eyepiece, odds are you already know the Nagler reputation. Crisp, clear, wide, well corrected. But unlike some in the series, it's not a huge, heavy grenade. It's a keeper. (Posted on 10/6/2018)
Review by:
Really one of the most wonderful eyepieces I've used (out of a few dozen); I find the 82 degree FOV to be about optimal and the clarity and sharpness across the field is breathtaking. One aspect I particularly enjoy is the small size and light weight - almost feels like a Plossl and won't upset the balance of a smaller scope/lightweight mount. I'm not a fan of huge, heavy eyepieces. There's also something about the mechanical quality and design of this eyepiece I enjoy. One caution - in my opinion, the eye relief is just right if you don't need to wear glasses; if you're a full-time eyeglass wearer or you observe under very cold conditions you may prefer more eye relief.
