Testbericht zu den 62° LER Okularen

Von Thorsten Zeiger, Volkssternwarte Niederrhein

Bei einem sehr guten Seeing konnten wir, die Volkssternwarte Niederrhein, endlich unsere neuen Okulare der 62° Serie von Explore Scientific ausprobieren. Dies habe ich mal gleich zum Anlass genommen, über die Erfahrungen und Tests zu berichten.

Ich fange mal mit der Verpackung an. Die Okulare liegen gut geschützt, quasi "wohl gebettet" in einem Karton mit jeweils passender Schaumstoffauskleidung. Sehr gut geeignet, wenn man öfters und schnell mal bei der Beobachtung zwischen verschiedenen Okularen wechselt. Wir haben uns direkt für alle sieben erhältlichen Größen entschieden.

Beim Auspacken fiel schon vorher die sehr gute Verarbeitung der Okulare auf. Die Steckhülsen, bei den 40mm und 32mm in 2", bei den anderen Größen in 1 1/4" Ausführung, laufen am oberen Ende konisch zu, sodass ein Herausfallen bei gelöster Klemmschraube verhindert wird. Wir benutzen ein 14" Schmidt-Cassegrain GPS auf Säule und Polhöhenwiege. Dazu ein Zenitprisma, und gerade hier ist es wichtig, ein Herausfallen des Okulars zu verhindern. 

Nun aber zu Wesentlichen:

Optische Eigenschaften

Die optischen Eigenschaften sind erstaunlich. Die Schärfe und Farbtreue bis an den Bildrand (wichtig bei bildausfüllenden Beobachtungen wie Mond oder Sternhaufen) beeindrucken.

Einblickverhalten

Das Einblickverhalten ist auch für Brillenträger tadellos, da man sehr gut beim Abstand zur Linse variieren kann, ohne "etwas zu verpassen". Alle Okulare sind mit ausklappbaren Augenmuscheln bestückt. 

Preis-Leistung

Da wir im Besitz einiger Okulare aus den verschiedenen Preissegmenten unterschiedlicher Hersteller sind, können wir die Qualitäten sehr gut beurteilen und vergleichen.

Fazit

Ich kann sagen, dass dem Hersteller hier ein großer Wurf gelungen ist, sowohl optisch wie auch verarbeitungsmäßig qualitativ hochwertige Okulare auf den Markt gebracht zu haben.

EXPLORE SCIENTIFIC 68° Ar Eyepiece 16mm (1,25")
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.

BRESSER NANO NT-114/500 Telescope
NEW - now including a high-quality aperture solar-filter for safe observation of sunspots, eclipses and planet transits. Great telescope for night and solar observation. The BRESSER NANO NT-114/500 telescope is the perfect combination of a large Newtonian mirror with a short focal length. The advanced observer who has discovered that light gathering is a more important factor than magnification, will especially appreciate the large 114 mm mirror. Enough light can be reflected into the eyepiece to be able to see even the most distant objects in our solar system at great detail. Suitable also for traveling and to observe large open star clusterns and the milky way. The telescope arrives with a wide array of accessories and almost pre-assembled - observation can start immediately. The BRESSER NANO is a light-to-medium-duty alt-azimuth mount with tripod designed to quickly and easily accept small to medium sized refractors, such as the AR-90s, AR-102s, AR-102xs and the ED-80 APO. Lightweight, fast Newtonians will also match up nicely with the BRESSER NANO AZ mount. As long as your telescope does not exceed 8 pounds and has a Vixen-Style Universal Dovetail bar for mounting the telescope to the mount head, you are good to go. The stainless steel tripod that comes standard with the BRESSER NANO AZ mount has adjustable legs and a wide foot print, which makes the tripod more stable. Spreader vanes with an acessory tray locks against the inside of the legs to secure the tripod even further, and keep vibrations to a minimum. Do you want to capture what you see ? With the included smartphone holder bracket you can use your smartphone to easily take colour pictures of celestial objects - like through a telephoto lens ! With the included camera adapter ring T2 you can also attach your DSLR or CCD camera direct to the focuser in order to capture high resolution pictures of the Moon by using short exposure times.Please note: Reflector telescopes with optical design “Newton” are very good for astronomical observing at the starry night sky. But these telescopes are not well usable for observing landscape and nature during daylight. Therefore we suggest BRESSER refractor (lens) telescopes for landscape and nature observing.FEATURESHigh quality and compact reflector telescope Richfield telescope also for traveling Easy to use BRESSER NANO AZ Mount Telescope arrives almost pre-assembled Large 40mm secondary mirrorDiffraction limitted optics for ideal sharpness and contrastMagnification with supplied accessories: 20x, (max. suggested: 228x) Focal distance, aperture ratio: 500mm, f/4.4 Stainless steel field tripod Smartphone holder bracket included - for taking pictures Eyepiece diameter: 31.7mm (1.25") Telescope for night and solar observationSCOPE OF DELIVERYOptical tube Messier NT-114/500 BRESSER NANO alt/azimuth mount Stainless steel tripod with accessory tray Eyepiece: BRESSER Super Plössl 26mm Red dot finder Aperture solar-filterSmartphone camera adapter Camera-Adapter Ring T2 (M42x0.75mm) Star chart software & rotatable star-map
