EXPLORE SCIENTIFIC 82° Ar Eyepiece 11mm (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.

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.

The TELRAD viewfinder is a projection finder that can be installed on any telescope and makes it child's play to align the telescope with the starry sky.The TELRAD viewfinder is a practical alternative to classic optical viewfinders and illuminated red dot viewfinders. You can see the complete starry sky without magnification, and not just a small section as with a normal optical viewfinder. Against this background of the starry sky, three red luminous concentric rings are projected, with apparent diameters of 4 degrees, 2° and 0.5° in the sky. Move the telescope so that the object you are looking for is in the inner ring, and the telescope points in the right direction. Because the object you are looking for is inside the ring, it will not be irradiated like a normal illuminated red dot finder.The base of the TELRAD viewfinder is self-adhesive and can be mounted on all telescopic tubes from about 10cm diameter. The length of the base is about 18cm. This base remains on the telescopic tube, the TELRAD viewfinder itself can be removed or attached at any time by means of the attached quick coupling. The TELRAD is powered by two normal AA batteries (not included).There are star atlases, like the "Deep Sky Travel Atlas" from Oculum-Verlag, and planetarium programs for the PC, like the program "Stellarium", where the three rings of the TELRAD are already drawn or can be displayed around the interesting celestial objects. This makes finding these celestial objects a real walk.FEATURESTELRAD projection finderIlluminated rings of 4 degrees, 2° and 0.5° in the skySee the complete starry sky without magnificationEasy installation and useCan be installed on nearly every telescopesBase with quick release coupling included Powered by two AA batteries (not included) Very long battery life because of LED technologySCOPE OF DELIVERYTELRAD viewfinder with projector and battery compartment TELRAD base with quick-release coupling for the viewfinder Adhesive tape for attachment to 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 Messier 8'' dobsonian is simply a breakthrough. Despite of its low price this telesccope offers a versatility and quality rivaling a lot more expensive telecopes. The optical diameter of 203mm (8'') does not restrict your observations on solar system objects like the moon or the planets - you can reach farther into the sky and explore globular and open clusters, nebulae and galaxies. With that telescope those objects are beginning to show structures: globular clusters are no longer only fuzzy blobs, but are resolved into masses of individual stars. Nebulae, that can only be barely detected in smaller scopes, reveal structures within. The telescope is setting a new standard in versatility: the excellent Hexafoc focuser boosts a free diameter of 65mm (2,5'') so that you do not have vignetting in big widefield eyepieces that is caused by smaller focuser barrels. The big altitude wheels handle those big, heavy eyepieces without problems - and when you intend to load even more (like a binocular viewer with two eyepieces) then you can move the tube in its tube rings and achieve balance within seconds. The excellent rigidity of the focuser makes focusing a snap - even for astrophotography. This is another virtue of this highly versatile telescope system: you can remove the altitude wheels from the tube rings, attach a dovetail and use the optical tube on a equatorial mount for astrophotography - in minutes. The focuser is handling even heavy cameras tilt and shifting-free. You are extremely demanding in your image sharpness? No problem - with the optional 10:1 gear reduction sharp images are easy. If you consider, that the focuser is that part of the telescope that is used most often, you will recognize the quantum leap this Hexafoc represents in a telescope of this price range. With the included standard accessories (6x30 finder and 25mm SPL-eyepiece) the telescope is ready for observing. If you need to transport or store the telescope as compact as possible you will like this: the rocker box of the 8'' BRESSER Messier assembles and disassembles extremely easy and fast due to the use of metal standard furniture fasteners. So you can transform the bulky rocker box into a handy flat package of boards. This telescope is setting a new standard in usability, versatility and performance in its price class.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.

The new BRESSER Nebula 6 EQ/AZ Wifi-Network Mount is a precise and quiet telescope mount – ideal for astrophotography. The controller box offers numerous central connection options for various accessories such as cameras, filter wheels, and motor focusers via USB (2.0/3.0), simplifying the setup of a professional astro-photography machine. BRESSER relies on innovation paired with quality Made in Italy for this top-class product. The long-standing experience of the manufacturer in mount construction guarantees a high-end device with first-class functionality and highest reliability. Additionally, the in-house development team for hardware and software in Italy ensures quick response times in technical support and the adaptation of new device drivers. True to the motto "Professionals at work!" The mount is controlled via pre-installed web app software, accessible via Wifi and an Ethernet cable connection. The philosophy behind the Nebula GoTo system is to provide the user with a control system independent of a normal PC, which can be remotely controlled in all its functions via a smart device such as a mobile phone or tablet. However, this does not exclude the traditional use of computers of all types and brands, which can be connected to the system either wired or wirelessly. The BRESSER Nebula GoTo System Controller is a Raspberry Pi 4 microcomputer, which allows complete control of the setup (mount, camera, etc.) without the need for any other external device. The BRESSER Nebula GoTo system is already equipped with all Linux-based applications necessary for performing all astrophotographic functions.The existing INDI environment allows the control of almost all devices (cameras, filter wheels, rotators, including observatory domes), necessary for conducting local or remote astrophotography sessions. The system also offers high flexibility for users who prefer to use traditional computer client applications such as Cart du Ciel (Star Chart), TheSkyX, SkySafari, Stellarium, and other planetarium programs as well as SGP, Nina, CCD Ciel, and other astrophotography tools. This complete compatibility is ensured through the adoption of the Alpaca communication protocol, which allows the use of traditional ASCOM platform drivers for native INDI devices. State-of-the-art mount construction The BRESSER Nebula mounts are CNC-manufactured from stainless steel and aluminum. The simple and functional design is thanks to a renowned Italian mount manufacturer, who has designed and now also manufactures these fine BRESSER products 100%. So, look forward to a stable yet easily transportable mount, which despite its light weight of only 16 kg (including tripod) allows a high load capacity of up to 25 kg. Visual Observation For visual observation and direct use, control the mount with the hand control box included in the package. Alternatively, connect the Nebula 6 via WLAN directly to your smartphone or tablet and use the virtual hand control box. Of course, all adjustment parameters can also be adjusted via the web application. The user interface is deliberately simple and clear to ensure intuitive operation. Astrophotography Here, the Nebula mount shows its full strength. Whether mobile or stationary, remote capability is crucial. Connect your laptop or PC either via WLAN or with an Ethernet cable (recommended for faster data transfer) directly to the Raspberry-Pi control unit of the mount. Then use the pre-installed software Kstars/EKOS to control the mount and all external devices such as cameras, motor focus, filter wheel, etc. Alternatively, you can also directly control the unit with your own software. Applications such as Cart du Ciel (Star Chart), TheSkyX, SkySafari, Stellarium, and other planetarium programs as well as SGP, Nina, CCD Ciel, and other astrophotography tools can be used without any issues. 2-in-1 Mount with EQ and AZ Mode If required, the Nebula can be switched from the equatorial mode to the azimuthal mode. This is particularly advantageous for observing nature or tracking satellites. Thus, the mount can be used for various applications and is not limited to astronomy only. Attachment of up to two optics Would you like to adapt multiple optics? No problem. Simply use the option to replace the counterweight bar with another telescope. Use the second optic simply as a counterweight to the main telescope. Set the Nebula 6 to azimuthal mode, remove the counterweight bar, and screw on an extension adapter with a suitable second telescope clamp directly to the mount.
