Product Info

Manufacturer Description

Please note - This eyepiece is Argon-purged; it is not Nitrogen-purged as indicated in the photos above.

Using advanced computer design, combinations of low dispersion and high refractive index optical glasses, and durable multilayer deposition coatings, Explore Scientific 100° Series hyper-wide field eyepieces are optimized to produce high contrast, high resolution, and superior flat field characteristics. And yes, they are indeed ruggedized and waterproof to withstand the outdoor environment.

The visual effect of these eyepieces with their long eye-relief and their 100° apparent field is an extreme full-immersion experience. You have to try it understand the visual impact that these eyepieces produce.

Like all Explore Scientific eyepieces, the lens elements of the 100° eyepiece are meticulously cleaned and aligned before being installed in their precision machined lens barrels.

Each lens and lens grouping have EMD (Enhanced Multilayer Deposition) Coatings and are edge-blackened to eliminate light scatter and maintain image contrast. Contrast is further enhanced with baffles that mask and deflect unwanted stray light.

Each 100° Series Argon-Purged Waterproof eyepiece is internally sealed and purged with inert, dry argon gas to prevent internal fogging, to halt the intrusion of fine particulates and fungus, and to maximize the life of the internal coatings. To make sure, every 100° eyepiece is tested by submerging them down to 1 meter of water for 30 minutes.

Explore Scientific's eyepieces are backed with their exclusive Explore STAR Transferrable Extended Life of the Product Warranty. Limited Warranty is one year, which converts to the Explore STAR Transferrable Extended Life of the Product Warranty when product is registered within 60 days of purchase. We think that you will find Explore Scientific eyepieces rank among the finest obtainable and represent an outstanding value.

      5.0 A Must Have For Dobsonian Telescopes!!!

      Pros:

      Easy to Use,Quality Lenses,Strong Construction,Accurate

      Cons:

      Heavy

      Comments:

      For that all immersive view, clear, very high contrast, no pincushoning effect, no blackout effect, hard to see the edge of field because it is so wide! I used a 2x barlow with this on Moon, Jupiter, Orion Nebula, M51 and star clusters to seriously test optical resolution, Excellent viewing! small lunar craters are easier to see, Jupiter's rings show more contrast.
      An all around must have eyepiece.

      5.0 Great Eyepiece

      Pros:

      Strong Construction,Quality Lenses

      Cons:

      Comments:

      Very nice high quality eyepiece. I also have an Ethos and although this one is a different focal length and can't compare apples apples it seems on par with the TV as far as build quality and sharpness of the stars across the entire 100 degree field. Also great service from Agena with the usual fast shipping.
