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.

Everything I had hoped for!Pros:
Easy to Use,Quality Lenses,Strong ConstructionCons: Comments:
I was very glad to see this Explore Scientific 5.5mm 100 degree eyepiece become available. I have the other focal lengths of this design (the 9mm, 14mm, and 20mm) and I find them to give fantastic views and are extremely comfortable to use. My hope was that this 5.5mm 100 degree eyepiece would follow suit, and I was thrilled to find that it certainly does!!! The views are sharp and bring out details in planetary nebulas, small galaxies, as well as fine detail on the moon and Jupiter. This eyepiece is every bit as comfortable to use as the rest of the line up in my 9.25 SCT telescope. No blackouts, or other distortions...I simply step up, put my eye in the cup and enjoy the view. Perfect!
I would highly recommend this eyepiece for your high magnification needs.
