EXPLORE SCIENTIFIC 62° LER Eyepiece 9mm Ar

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.

Warning notes
  • General safety instructions DANGER Risk of eye injuries! Never look directly at the sun or near the sun through this device. There is a risk of blindness! Children should only use the device under supervision. Keep packaging materials (plastic bags, rubber bands, etc.) away from children! There is a risk of suffocation! FIRE HAZARD! Do not expose the device – especially the lenses – to direct sunlight! The light concentration could cause fires. RISK of material damage! Do not dismantle the device! In case of a defect, please contact your dealer. They will contact the service center and may send the device in for repair. Do not expose the device to temperatures above 60°C!
  • Never look at the sun through an eyepiece/telescope without a certified protection filter. A moon filter can never be used for solar observation. The moon filter is only suitable for moon observation. The solar filter must be mounted in front of the telescope opening, not at the eyepiece. Otherwise, the concentrated light beam through the optics will immediately destroy the filter foil, leading to severe eye damage, including permanent blindness.
  • Never leave the optics unattended. Children and inexperienced adults could point the telescope at the sun without proper precautions and lose their eyesight.
  • Do not expose the device to high temperatures.

BRESSER Barlow Lens 2x 31.8mm/1.25"
With the usage of barlow lenses, you can extend the equivalent focal length of telescopes and hence increase the magnification of your observed targets. Subsequently, you can use lower power eyepieces in Barlows to act as much more powerful eyepieces, but retain the larger ocular size and more comfortable viewing that comes with lower power eyepiece designs.Due to their two lens design, these Barlow lenses provide a brilliant image quality for the whole visual field and are suitable for observations and photography.  The black coloured Barlow element cell in this BRESSER Barlow Lens 2x 31.8mm/1.25," can be unscrewed and has the same thread as 1.25" filters, allowing it to be mounted in 1.25" eyepieces, t-adapters and other accessories, giving you flexibility of use and the ability to vary magnification in different accessories.  For instance, the black Barlow cell screwed into the average length nosepiece of a standard push fit t-adapter will give around 1.6x magnification on an attached DSLR.  This can be very useful when trying to get to photographic focus with some Newtonians and Solar Telescopes, which lack the necessary amount of in focus travel to get a camera to a prime focus position.FEATURESsuitable for observations and photographydoubling of the focal lengthtwo lens designfully multi-coatedWHAT'S INCLUDEDBarlow lens (1pc)

EXPLORE SCIENTIFIC 1.25" Variable Polarizing Filter
Universally usable variable polarizing filter with a  1.25" 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 1.25" 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 housing1.25" filter thread on both sidesSCOPE OF DELIVERYpolarizing filterprotective box

EXPLORE SCIENTIFIC 1.25" UHC Nebula Filter
One of the most important obstacles for the exploration of the night sky is the brightening of the night sky by artificial lights, such as streetlights. The night sky is not really dark in the vicinity of towns or cities, which reduces the visibility of objects beyond the solar systems enormously. Depending on the type of the celestial object it is possible to increase the contrast dramatically by blocking the annoying artificial light. The EXPLORE SCIENTIFIC UHC filter uses a characteristic property of the so called emission nebulae. Those objects glow in special colours, their emission lines. Those emission lines are linked to chemical elements - in this case hydrogen at 486nm and 656nm, plus oxygen at 496nm and 501nm. The Explore Scientific UHC nebula filter blocks all other colours (and thereby nearly all of the artificial light) and only the emission line of the hydrogen and oxygen can pass the filter. The result is astonishing: suddenly nebulae are visible at locations that were completely empty without filters. In suburban skies for example the Owl-nebula M97, the Veil-nebula NGC6992 or even the bright Dumbell-nebula M27 are not clearly visible. By using this filter you can see the nebulae and their structures without problems. A must for every visual observer. The EXPLORE SCIENTIFIC nebula filters come with a individual test certificate - your guarantee to receive a premium filter.FEATURESenables the observation of emission nebulaeblocks almost the entire artificial lightonly the two emission lines of hydrogen and oxygen passes the filterWHAT'S INCLUDED1x 1.25" UHC nebula filter

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.

EXPLORE SCIENTIFIC 82° Ar Eyepiece 14mm (1,25")
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.
