The good folks at Explore Scientific are clearing out the last of their nitrogen-purged 100-degree eyepieces (the new models are argon-purged), and we've purchased the entire stock of these 9mm and 14mm ultra-wide-field oculars.
These big 2" eyepieces give incredible 'spaceship window' views of galaxies, star clusters, and nebulae framed in inky-black fields of pinpoint stars. With such a huge field of view, celestial objects are easier to locate, and with non-driven telescopes like Dobsonians the object will stay in the field of view for a long time before you need to adjust the scope.
All eyepieces are new, old stock and they're subject to the full manufacturer's warranty. These are great deals, but we're limited to stock on hand, so they won't last long.
Please note that no free Agena bolt case (eyepiece storage container) is included at this price but can be purchased separately. Closeout, so all sales are final!
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 Nitrogen-Purged Waterproof eyepiece is internally sealed and purged with inert, dry nitrogen 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.
