Testbericht zu Explore Scientific 92° LER Okular 12mm

von Abenteuer Astronomie

2017-01-01

Die Zeitschrift Abenteuer Astronomie hat in der Ausgabe 1/2016 im Okulare und Zubehör Praxis-Check das Explore Scientific 92° LER Okular 12mm ausgiebig getestet. Ein Kernthema war die Eignung für Brillenträger.

Okulare mit 100° scheinbarem Gesichtsfeld haben in den letzten Jahren den Markt und auch die Beobachtungserfahrung revolutioniert – aber nicht für alle Beobachter. Brillenträger und Freunde eines bequemen Einblicks mussten bislang mit deutlich kleineren Gesichtsfeldern auskommen. Explore Scientific hat diesem Thema nun die 92°-LER-Okularreihe gewidmet.

Positiv beeindrucken konnten die sehr gute Abbildungsleistung und der insgesamt hervorragende Eindruck für Brillenträger und Freunde eines unkomplizierten Einblicks.

Das sehr positive Fazit:

Die Okulare machten insgesamt einen hervorragenden Eindruck. Für Brillenträger und Freunde eines unkomplizierten Einblicks eröffnet die 92°-LER-Serie ganz neue Anblicke bei insgesamt sehr guter Abbildungsleistung. Die kleinen Abbildungsfehler können dies nicht schmälern, da sie in der Praxis selten erkennbar werden. Aufgrund des unkomplizierten Einblicks ist es auch naheliegend, an den Einsatz der Okulare bei Sternwarten-Führungen zu denken. Das gerade noch eingetroffene 17mm Serienexemplar lässt sich übrigens nur anhand der Seriennummer vom Prototypen unterscheiden.

Product information "EXPLORE SCIENTIFIC 92° LER Eyepiece 17mm"

If a observing session is a relaxing and joyful experience is heavily dependend on the choice of eyepieces. People wearing glasses very often have the problem to see the entire field of view when they are using eyepieces with large apparent fields. This problem is now history. The new 92°- LER eyepieces by Explore Scientific do not only offer excellent image sharpness and high resolution and contrast over the enourmous full field of view - you can see that full field without problems even with glasses on. Fatigue due to tense head positioning and strained viewing simply does not happen because of the excellent viewing comfort these eyepieces provide even to observers wearing glasses. Enjoy the unique combination of excellent image sharpness out to the edge of the field even for fast optics, superior contrast and unmatched viewing comfort. Eyepieces with perfect combinations of various modern glass substrates and highest standards in manufacturing, quality control and service are a tradition at Explore Scientific Tradition - the outstanding resolution and sharpness to the very edge equal that of our eyepieces of the 100° line.
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 patentet EMD"-coating teams up together with internal baffles to produce high contrast images and to prevent 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.

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.

EXPLORE SCIENTIFIC Ultra Light Dobsonian 406mm GENERATION II

Ultra Light Dobsonian 406mm GENERATION II - with completely redesigned and improved construction. No telescope type has influenced amateur astronomy as radically as the dobsonian telescope. Before the introduction of this telescope type by John Dobson the vast majority of amateur telescopes were small inadequate refractors on shaky mounts - just good enough to show the polar regions on mars or the rings of Saturn. Bigger telescopes, like the Schmidt-Cassegrain telescopes, were restricted to the relatively small group of amateurs that could afford them.The brilliant combination of simple - but effective - mechanics and the largest aperture available led to a worldwide triumph of this concept. No other telescope type offers you so much light for your money as a good dobson. We have taken the motto "held together by gravity and driven by yoghurt power" and offer a modern version of the classic - designed by amateur astronomers for amateur astronomers. Despite its large aperture the telescope can be transported easily even in small cars and is assembled within minutes without tools. The construction was optimized for maximum rigidity with a minimum of mass. The combination of big altitude wheels and a optimized aluminium-sandwich construction allows for small movements even at high magnifications. The focus position is already positioned to accept our coma-corrector. The ideal workhorse for the deep-sky enthusiast. A telescope with 406mm aperture gathers more than 3300-times more light than the naked eye. Details on planetary surfaces stand out even to unexperienced observers, and countless deep-sky objects show details. Bright globular clusters are resolved down to the core and the view of the lunar terminator will provide a unforgettable experience.

EXPLORE SCIENTIFIC 68° Ar Eyepiece 40mm (2")

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 100° Ar Eyepiece 14mm (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° Ar Eyepiece 30mm (2")

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.

BRESSER Full HD Deep-Sky Camera & Guider 1.25"

BRESSER Full HD Deep Sky Camera with autoguider: a great camera for different types of astrophotography and for autoguiding. Not only suitable for planets, but also for deep-sky objects such as galaxies, nebulae and star clusters. Dedicated ToupSky Astro Imaging software supports video preview, video recording, video processing, image capture and processing, dark field correction and raw data output. Easy to use, but with professional results. One of the main features of the new backlit SONY IMX290 CMOS sensor is its high light sensitivity, which makes it possible to detect deep-sky objects without active cooling. SONY has increased the quantum efficiency at 533 nm wavelength up to 77%, which is much better than other CMOS sensors have been able to achieve in the past. Connect this camera to a guidescope and attach the camera's built-in ST-4 port, directly to your telescope's equatorial mount guide port and autoguide - using many popular audioguiding programs (PHD, Guidedog and more). Autoguiding enables you to take accurate pictures with long exposure times of several minutes. Thanks to the extra light-sensitive camera, you now always have a suitable guide star to hand, even using short exposure times. An ST-4 protocol connection cable is also included. Simple automatic tracking at its best. You can use this camera with all guiding telescopes, or off-axis guiders that accept a 1.25 " tube, 1.25" filter thread (M28.5x0.6) or C-mount adapter thread (1 "x1 /32"). IMPORTANT NOTES: This is not a stand-alone guider camera. You always need a Windows 10/11 computer to take pictures and for autoguiding. The autoguider software is not included. You can use PHD2 Guiding, Guidedog, Metaguide, Guidemaster (freeware) or AstroArt, MaxIm DL (paid).
