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.

Explore Scientific 82° Series™ extreme wide field eyepieces are optimized to produce high contrast, high resolution, and superior flat field characteristics. The visual effect of these 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 a twist-up rubber eye-guard that raise to the desired height for the comfort of the observer, and 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. All 82° Series eyepieces are fully multi-coated and edge-blackened to produce maximum contrast.

A new focal length joins the Explore Scientific line of inert gas-purged Waterproof Eyepieces with the 3mm 52° LER Series Eyepiece. A logical companion for the grab-and-go ED APO 80mm f/6 Air-Spaced Triplet, this eyepiece produces 160X which will perform very well with good seeing conditions on planetary objects, and to split double stars. On the ED APO 152 at f/8, 405X is achieved without the use of a Focal Extender or Barlow for those nights of near perfect seeing, with a very comfortable 15mm of eye relief. Comfort, Quality, Value. The Explore Scientific 52° LER Series Most short focal length eyepieces are excellent flat-field multi-element oculars that can transform your visual astronomy experience. With an apparent field of view of 52 degrees, these eyepieces offer incredible value in a very nice eyepiece. Expect exceptional quality and value versus a comparably priced Plossl.  These eyepieces are the choice for observers wearing glasses - with excellent performance and durability. The rubber inlet and the foldable eyecups make handling and using in the field easy. 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.SPECIFICATIONSLarge eye distance, large field and great image sharpnessExcellent viewing position for people with glassesExcellent field sharpness even with fast optics52° 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 DELIVERY52° EyepieceDust coversProtective bag

Bitte beachten Sie, dass für Refurbished Artikel generell 12 Monate Garantie gelten.Ob eine entspannte und eindrucksvolle Beobachtung mit einem Teleskop möglich ist, wird entscheidend von der Okularwahl beeinflusst. Als Brillenträger hat man bei Okularen mit sehr großem Eigengesichtsfeld oft das Problem, das Gesichtsfeld mit Brille voll zu überblicken. Dieses Problem gehört jetzt der Vergangenheit an. Die neuen 92°-Okulare von EXPLORE SCIENTIFIC bieten nicht nur eine ausgezeichnete Randschärfe auch bei schnellen Optiken und ein riesiges Gesichtsfeld - Sie können durch den extrem großen Augenabstand auch das gesamte Gesichtsfeld mit Brille problemlos überblicken. Ermüdung durch verkrampfte Kopfhaltung und angestrengtes Beobachten treten durch das ausgezeichnete Einblickverhalten dieser Okulare nicht auf. Genießen Sie die einmalige Kombination aus hervorragender Abbildungsqualität bis zum Bildfeldrand auch bei schnellen Optiken, ausgezeichnetem Kontrast und unerreichtem Beobachtungskomfort. Okulare mit perfektem Zusammenspiel von unterschiedlichsten modernen Glasmaterialien und höchste Standards in Fertigung und Service haben bei EXPLORE SCIENTIFIC Tradition - hervorragende Abbildungsqualität und Schärfe bis zum Bildfeldrand sind gleichwertig mit den Okularen unserer 100°Serie.Diese Okulare stehen für Leistung und Langlebigkeit.
