EXPLORE SCIENTIFIC 100° Ar Eyepiece 9mm (2")

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.

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 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.

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 waterprrof, 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!

The visual effect of these new 8,5mm 82° LER eyepieces with their long eye-relief and their 82° apparent field is truly a full-immersion experience. Your eye is relaxed, allowing you to easily use the averted vision technique to study faint details across a huge field-of-view. The 82° Series eyepieces come with foldable eyecups make handling and using in the field easy. As experienced astronomers know, eye comfort is critical when trying to observe at the visual limits of the telescope. To keep internal reflections to a minimum, all internal surfaces of the eyepiece barrel are flat black, as well as the edges of the lenses themselves to minimize the scattering of light within the lenses themselves.These eyepieces are the choice for observers wearing glasses - with excellent performance and durability. The patented EMD-coating produces high contrast images and prevents reflexes and ghosting. The argon purging effectively prevents internal fogging, and you don´t have to deal with dirt, fungus or cleansing fluids getting between the lenses. The eyepieces are sealed - this makes sure you will be able to enjoy these eyepieces for many years to come.Comfort, Quality, Value. The Explore Scientific 82° LER Series Most short focal length eyepieces are excellent flat-field multi-element oculars that can transform your visual astronomy experience. These extreme wide field eyepieces are optimized to produce high contrast and high resolution characteristics.SPECIFICATIONSLarge eye distance, large field and great image sharpnessExcellent viewing position for people with glassesExcellent field sharpness even with fast optics82° apparent field of viewArgon-purging prevents internal fogging, the sealing facilitates cleaningPatented EMD-coating to maximize contrastBlackened lens edges to avoid reflexesAll eyepieces of this series are parfocalStainless steel barrel with conical security cutoffDust covers and protective bag includedSCOPE OF DELIVERY82° EyepieceDust coversProtective bag

The three-lens design of the EXPLORE SCIENTIFIC ED-Apochromats provides everything an amateur astronomer desires - at a reasonable price. The construction with Hoya FCD001 ED glass has two air spaces and provides a level of correction so superior to the two-lens constructions, that are common in this price class, that you will see the difference immediately. This excellent optical performance teams up with a high precision mechanics - the result is a telescope on a level that is setting a new standard in it´s price class. Astrophotographers will love this telescope - a optional field flattener is available and makes the telescope perfect even for cameras with a large chip format.These very popular EXPLORE SCIENTIFIC Triplet ED APO Refractors we do offer in 3 different product lines:Essential Line: HOYA FCD-1 Glass lens, AL-Tube, 2.0'' Rack & Pinion Focuser with 1:10, 2.0'' Star Diagonal 99% Reflectivity (see Part No. 0112084(AL), 0112106(AL), 0112132(AL)), 0112155(CF + 3''FT)).Professional Line: HOYA FCD-100 Glass lens, AL/CF-Tube, 2.5'' HEXAFOC Focuser with 1:10, 2.0'' Star Diagonal 99% Reflectivity (see Part No. 0112086(AL), 0112108(AL), 0112109(CF), 0112134(AL), 0112135(CF)).High-End Line: OHARA FPL-53 Glass lens, Carbon (CF) Tube, 3.0'' Feather-Touch Focuser with 1:10, 2.0'' Star Diagonal 99% Reflectivity (see Part No. 0112165(CF)).IMPORTANT NOTE: this telescope is supplied without finder or flight case.
