Features
- IDEAL MAGNIFICATION POWER FOR DEEP SKY TARGETS: This waterproof eyepiece has a 30mm focal length that produces a low magnification power ideal for observing deep sky beauties like nebulae, galaxies, star clusters and more. Under steady skies with excellent atmospheric conditions, this low magnification power will pick up faint objects that cannot be seen at higher magnifications and will also show more of the celestial target within the eyepiece.
- BROAD FIELD OF VIEW: The wide 82-degree apparent field of view of this series of eyepieces makes it easier to locate objects in the night sky as well as explore various regions of large celestial treats like nebulae. The generous apparent field of view also relaxes your eye for a pleasant viewing experience and allows you to use averted vision to see fainter targets.
- HIGH RESOLUTION VIEWS WITH SHARP CONTRAST: This eyepiece generates brilliant views with crisp definition and rich contrast by using edge-blackened optical elements made of low-dispersion glass with a high refractive index. In addition, each lens element is fully multi-coated with durable enhanced multi-layer deposition (EMD) coatings that maximize light transmission.
- WATERPROOF HOUSING: Each 82-degree Series eyepiece is purged with an inert gas and O-ring sealed to create a waterproof environment that is impervious to internal moisture build-up and prevents contaminants like dust from entering the ocular housing.
- USA SUPPORT: Should you ever have an issue or question, you can always be assured of excellent support from our Customer Service team based in Springdale, Arkansas, USA.

I love Explore scientific eyepieces, they're very well made and tested to last a life time. I'm not too good at describing the technical aspects of optics, this is just a really nice eyepiece. I primarily use a 10" Dob and this is a perfect fit to my eyepiece collection. I have Nagler's but Explore Scientific is right up there in my opinion and at a very affordable price. This eyepiece is a brute, it weighs 2 lbs 4 oz some may find this a problem but it doesn't really bother me. I like the feel of the eye cup, it's very comfortable viewing for extended periods. Finding objects like M13, M51 are much easier now. I was very surprised that there is such little loss of light considering how many pieces of glass are in it. Last night I found myself just touring the night sky with no particular agenda, just enjoying the view from space...this is how I keep the hobby fun! I will have the entire set of these before long...you can not go wrong for the money!

It's seriously crazy that you can buy eyepieces in China now that rival the previous 10 years of Japanese made glass. This is extremely underrated - it's like a 31mm nagler, with better eye relief, for half the cost. Wowza.... In your hurry to buy one, don't overlook the weight. This is a beast, and you might need to change the balance of your dobson. But if you want the view, this is THE GLASS.

Got this eyepiece for use with my Meade LX90 12" scope. Love the wide field and sharp views - stars are pinpoints and the view is solid right our to the edge of the FOV. Also have an ES 2X Focal Extender, which I use frequently with this eyepiece for that same great results. Highly recommended!

Hi i was really disapponted in this lens, i have a celestron 23mm 82 digs. that is far more better than this one.

This eyepiece is noticeably better than my 32mm Orion Q70–sharper throughout the field of view and of course wider. I love the views I get with this eyepiece. It functions very well as a finder eyepiece and gives that “porthole” feel that people talk about with wide angle eyepieces. However, I can’t say that it is worth $200 more than the Q70 at my level of experience or budget. Perhaps I haven’t been in this hobby long enough (on and off for 7 years) or perhaps my (moderately slow) f/7 scope was forgiving enough to the Q70 so as to level the playing field a bit. All I can recommend is that you actually look through a variety of eyepieces and decide for yourself what the best value is. For me, this was a Christmas present to myself and I am happy enough with it, so I am keeping it.

Great eyepiece for the price. It is not a Nagler but you can't beat the price. Image quality is great. I use it in a custom built 16" dobsonian telescope.

What a view. Clear field edge to edge.

It's a heavy large eyepiece! I have not used it yet. But I'm sure it's better than the supplied eyepiece with my dob. It was cheaper on the Explore website last month. I hope it's as clear as my other two.
