These eyepieces with their huge apparent field of view not only gave the observer a panoramic visual experience, but they relax the eye so the observer could pay attention to subtle details for extended periods.These ultra-wide angle eyepieces played a critical role in the military for aiming at targets, and their long eye-relief counterparts helped reduce eye injury from recoil.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. This also maximizes 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.All 100° Series eyepieces are fully multi-coated and edge-blackened to produce maximum contrast.
The "Wow-effect" eyepiece: You see deep sky objects as if you were in space! It makes you forget that you are looking through a telescope. This makes up for an unforgettable observing experience, that even exceeds the expectations of demanding amateur astronomers. Of course, it has the same specifications as the already well established 100° eyepieces: inert gas purged, and waterproof, the high-end EMD coatings are protected from the outdoors. Dust, fungus, humidity and cleaning solutions cannot harm the precious eyepiece for years of observing to come!
With the introduction of the 68° Series we are pleased to make two important improvements in eyepiece manufacture, the first being 15 layer Enhanced Multi-layer Deposition (EMD™) coatings on all glass-to-air surfaces to gain maximum contrast and waterproofing the eyepiece with the use of Argon gas purging instead of standard Nitrogen gas. Although Nitrogen is a fine choice that will last for many years, Argon is a larger molecule that maintains its protective properties over a wider range of temperatures and is even more resistant to diffusion thereby further extending the protective waterproof environment of the eyepiece body.Through computer-optimized design, a careful selection of optical glasses, and enhanced multi-layer deposition coatings, the Explore Scientific 68° Series™ eyepieces produce long eye-relief and ensure high image-correction, a flat field, and high contrast across the entire image field. An excellent choice for those who make extended visual studies of detail with subtle variations of brightness, and for those who must wear glasses while observing.All 68° Series eyepieces are fully EMD (Enhanced Multi-Layer Deposition) coated and edge-blackened to produce superior contrast.
The Omegon 2x Barlow lens trebles the magnification when used together with an eyepiece. The 1.25" eyepiece is simply inserted into the Barlow lens and secured with the side locking screw. You then insert the complete assembly into the focuser. For example, if you normally get 20 x magnification with your eyepiece, this is then increased to 60 x with the Omegon Barlow lens. If you want to initially do without having to acquire a complete set of eyepieces, then this Barlow lens fits the bill.
