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.

The large diffusing lens results in a very large and evenly illuminated light cone, which can also be adjusted by a sliding mechanism. By using a power-saving LED lamp, the battery life (1 x AA-LR6) is up to 100 hours. Of course, the robust lamp housing made of aluminium is splash-proof according to IPX4 and therefore particularly well suited for outdoor applications.

EXPLORE SCIENTIFIC 82° Ar Eyepiece 11mm (1,25")
£175.00*
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.

EXPLORE SCIENTIFIC 2" Variable Polarizing Filter
£57.00*
£79.00*
(27.85% saved)
Universally usable variable polarizing filter with a 2" filter thread.This variable polarizing filter allows for a continuous adjustment of the image brightness. This is very helpful to level strong differences in contrast of different observation objects individually. Particularly for lunar and planetary observations but also for solar observations this filter prevents an outshining of details.Solar observations ONLY together with an adequate solar filter !!! Particularly when a Herschel wedge is used and with large objective lens apertures the use of the variable polarizing filter can reduce the brightness of the observation object to a confortable level. The large adjustment range of 40% to 1% light transmission and the neutral grey filter effect create a comfortable and unadulterated image.The handling is very simple. The desired filtering level is set by turning the two sides of the housing against each other.A 2.0" filter thread on both sides (female/male) allow for the simultaneous use of additional colour filters.FEATURESvariable polarizing filterindividually adjustable image brightnessmade from high-quality optical glassblack anodized aluminium housing2.0" filter thread on both sidesSCOPE OF DELIVERYpolarizing filterprotective box

EXPLORE SCIENTIFIC 2" CLS Nebula Filter
£75.00*
£83.00*
(9.64% saved)
Besides air turbulence, the brightening of the night sky is the biggest obstacle to observing faint objects beyond the solar system. Street lamps and other artificial lighting mean that the sky in human settlements is no longer really black. This affects the contrast and thus the perception of deep-sky objects. Depending on the type of celestial object, however, part of disturbing artificial light can be filtered out, making it easier to observe fainter targets.The EXPLORE SCIENTIFIC CITY LIGHT SUPRESSION - or CLS - filter uses the fact that the artificial lighting is not evenly distributed over the entire spectrum. These colours - in the case of the EXPLORE SCIENTIFIC CLS nebula filter, above all the typical colours of mercury and high-pressure lamps, used in street lighting - are suppressed, but the emissions of deep-sky objects are allowed through. With a slightly brightened sky, some relatively bright deep-sky objects are practically invisible with a telescope, for example the large galaxy M101. Using this filter makes observation much easier. A must have for any visual amateur astronomer. The CLS can also be used as a useful photographic filter - helping to improve the quality of your telescopic deep sky photos.The EXPLORE SCIENTIFIC nebula filters are delivered with an individual test report - so you can be sure of receiving high-quality filters.SPECIFICATIONS:eliminates disturbing light - e.g. from street lightingenables observation of faint deep sky objectsWHAT'S INCLUDED:1x nebula filter
