The sun's breathtaking sights aren't to be missed either; observe and photograph it safely with the provided solar filter through the PushTo AR-80/400. A true all-round telescope for both day and night! Get started immediately with the smart telescope The telescope is very easy to operate and can be started without much effort. The first steps only involve downloading the BRESSER PushTo Navigation Smart App and a brief initialization of the telescope. Then you will immediately see the current viewing direction via crosshairs on the star map displayed on the connected mobile device. This is made possible by the sensors integrated in the telescope and the Bluetooth connection to your mobile device. And thanks to the slip clutches built into both axes, you can easily move and adjust the optical instrument by hand. Clever celestial navigation with the smart telescope Once set up, simply select any object on the PushTo Navigation star map via touch, and navigation begins. The displayed direction arrows, which change in length and colour as you approach the object, guide you reliably to your destination. Meanwhile your telescope’s movements are mirrored on the star map in real time. Once you reach the destination, you can immediately marvel at the desired celestial body. Alternatively, you can choose an object from the extensive database. Or make it even easier and opt for one of the preset sky tours for spring, summer, autumn, and winter. And you can quickly enjoy observing your favourite objects over and over again – just save them! Impressive optics for compact and extensive objects The powerful refracting telescope with an aperture of 80 mm shows you many of the most popular celestial bodies particularly bright and contrast-rich. The moderate focal length of 400 mm also allows for beautiful broad views of large objects such as open star clusters and bright nebulae. Additionally, you will definitely be amazed when the moon craters and the Jupiter moons suddenly become visible through the smart telescope, and you perceive the famous ring of Saturn. Versatile celestial observation – with tripod or as a table device The included field tripod can be quickly adjusted to the appropriate height for comfortable use of the optical device. But even without a tripod, the smart telescope reliably shows you the wonders of the starry sky. That’s because the BRESSER PushTo AR-80/400 can be used as a super compact tabletop device.

Maksutov Newton MN-152 David H. Levy Comet Hunter Telescope Highly corrected optic for wide-field observation and astrophotography. Developed in collaboration with the famous "comet hunter" David H. Levy. The Maksutov-Newton system does have some pros and cons respectively to the classical newtonian design. Apart from the higher price the main disadvantage is the higher weight - the thick corrector lens at the front is the cause for this. The main advantage of the Maksutov-Newton compared to the classical newton is the sharpness of the field of view. Classical newtonian telescopes do show a sharp pinpoint star image only at the middle of the field of view - outside the optical axis they have a dominant abberation, the so called coma. This is inherent in the newtonian design, and therefore valid for all newtonian telescopes of all brands and not caused by manufacturing tolerances. Coma distorts the star image - the pinpoint star shows a tail, just like a small comet. This decreases sharpness and contrast considerably. The Maksutov-Newton shows a much sharper star image - for most applications the coma is not visible. This results in a high contrast image all over the field of view - for visual observations and for astrophotography with DSLRs alike. This makes the Maksutov-Newton a ideal all-purpose telescope, that is able to show a sharp field without the need for additional correctors.

Giant binoculars for observing the starry sky, nature and landscape. Observe the beauty of the starry sky at night and distant objects in nature during the day. Globular star clusters, glowing gas nebulae, the moon with its craters and even planets can be observed wonderfully on a clear night. But also all other distant things in nature and landscape, even ships and airplanes can be seen in detail. With the all-round binoculars of the EXPLORE SCIENTIFIC BT series, you can get up very close. Thanks to the large, light-gathering lenses and the professional coatings on all lens surfaces, these binoculars produce bright and brilliant images even at night and at twilight, providing a special viewing pleasure. The comfortable 45 degree viewing angle allows fatigue-free use even when the binoculars are tilted strongly.  Large binoculars can also be called a double refractor telescope One complete lens telescope with the full light gathering power is available per eye. Experience a whole new dimension of observing. Objects are reproduced almost vividly in these binoculars and observing with both eyes is basically very relaxed. Last but not least, this comfortable way of observation increases the recognition of the finest details and effectively prevents rapid eye fatigue. Extremely robust binoculars with magnesium housing, sealed and filled with nitrogen  The BT series binoculars are designed for tough outdoor use. The IPX6 sealed and nitrogen-filled design effectively prevents fogging of the internal optics even under difficult weather conditions. The very light magnesium housing saves weight and makes it easy to handle. Two EXPLORE SCIENTIFIC 20mm eyepieces of the 62 degree LER series already included. EXPLORE SCIENTIFIC is an established manufacturer of extremely high-quality eyepieces in the astronomy scene. An optical system is only as good as its weakest component. Therefore we have decided to deliver these giant binoculars with a pair of quality eyepieces of the 62 degree LER series. With an apparent field of view of 62 degrees and a focal length of 20mm, the BT-100 binoculars produce a 28x magnification. Thus these wide angle eyepieces offer a very good overview (field of view 2,3 degree) at moderate magnification. The large interpupillary distance of these LER (long eye relief) eyepieces of 15mm and soft silicone eyecups, which can be turned inside out, also guarantee a comfortable and relaxed view. For astronomy, a flat and sharp image field is advantageous and offers a particularly impressive viewing experience even during the day. Due to the waterproof design and the argon filling, these eyepieces are absolutely durable and easy to clean. Interchangeable eyepieces with 1.25 inch / 31.7mm plug-in diameter Adjust the magnification and field of view to your individual needs and choose from a wide range of available eyepieces. All eyepiece types with a plug-in diameter of 1.25 inch / 31.7mm can be used with the binoculars of the BT series. Especially recommended are EXPLORE SCIENTIFIC eyepieces of the 62 and 82 degree series with focal lengths from 8 to 26mm (see item No. 02188xx and 02196xx). The magnification can be varied from 21x to 70x (focal length binoculars : focal length eyepiece = magnification). The eyepieces are held in the binoculars by a precise brass compression ring clamp and guarantee a tilt free position.  Use of color and nebula filters for astronomical observations Increase the contrast and visibility of objects and details by screwing the corresponding filters directly into the thread of the eyepiece sleeves. The use of color and nebula filters must of course always be done in pairs. Suitable are all EXPLORE SCIENTIFIC screw filters with 1.25inch / 31.7mm diameter (see item No. 03102xx)  Comfortable 45 degree view and helical single focus The 45-degree viewing angle allows a relaxed observation position even when the binoculars are tilted strongly. Also the individual interpupillary distance can be adjusted in a range from 54 to 76mm. With the fine helical individual focusing, precise focusing is achieved effortlessly. Extendable dew caps The integrated dew caps can be removed in high humidity and cold conditions. This avoids fogging of the outer objective lenses and effectively shields additional control light coming in from the side. Integrated carrying handle A metal carrying handle located at the center of gravity facilitates transport and ensures a secure hold during tripod assembly. Suitable tripods and tripod connectionWhen using these large binoculars, a sturdy photo tripod with an appropriate load capacity is highly recommended. The connection is made via two 1/4 inch or one 3/8 inch threaded holes (standard photo tripod thread) in the tripod adapter of the binoculars. The ideal solution is to use the optional availlable EXPLORE SCIENTIFIC U-Mount with field tripod (item No. 0114300). This is specially designed for the large binoculars of the BT series and carries these devices absolutely safely. The excellent mechanism with adjustable friction in both axes allows easy moving and tracking. The binocular position is kept stable depending on the adjusted friction intensity. Vibrations are reduced to a minimum by the massive construction of the U-Mount and the large stainless steel tripod. Even at high magnification there are no vibrations and the finest details can be observed.FEATURES Large binoculars for observing the starry sky, nature and landscape Observe globular star clusters, glowing gas nebulae, the moon with its craters and even planets Also wild animals, ships and airplanes can be seen in detail Highly light gathering lenses produce a bright and high-contrast image All-round binoculars, but especially suitable in twilight and at night The comfortable 45 degree viewing angle allows fatigue-free use One complete lens telescope with the full light gathering power is available per eye Extremely robust binoculars with magnesium housing, sealed and filled with nitrogen Two EXPLORE SCIENTIFIC 20mm eyepieces of the 62 degree LER series already included 28x magnification and an apparent field of view of 62 degrees, true visible field of 2,3 degreesLarge interpupillary distance of 15mm to the eyepiece lens for comfortable viewing Eyepieces interchangeable and with standardized plug-in diameter of 1.25 inch / 31.7mm The magnification can be adjusted with optional eyepieces from 21x to 70x Precise brass eyepiece compression ring clamps for tilt-free fitColor and nebula filters can be used for astronomical observations Extendable dew caps prevent fogging of the outer objective lenses and stray light Integrated carrying handle facilitates transport and mounting on the tripod Tripod connection via two 1/4 inch or one 3/8 inch threaded holes (standard photo tripod thread) Tripod recommendation: EXPLORE SCIENTIFIC U-mount with field tripod (Art.No. 0114300) Objective type: Air spaced achromatic lens (2 elements/ 1 group) Coating: full multilayer coating on all optical surfaces Aperture, focal length and aperture ratio: 100mm / 550mm / F=5.5 Sealed to IPX6 standard and nitrogen filled: yes / yes Close focus distance: 25 meters Eyepiece mount diameter: 1.25'' / 31.7mm Adjustable interpupillary distance: 54 to 76 mm Helical single focus: yes BAK-4 prism system for a bright and high-contrast imageDimensions and weight of binoculars: 520 x 270 x 155mm, 6.8kg Housing color of binoculars:  white SCOPE OF DELIVERY Giant binoculars with carrying handle (without tripod)Eyepieces ES 20mm 62 degrees LER Series (2pcs)Precisely fitting foam insert for transport Dust covers for objectives and eyepiece sockets Instruction manual

You see better with two eyesThe BRESSER BinoViewer Deluxe makes it possible to observe astronomical objects in a relaxed way with both eyes and with considerably more detail than using one eye. The images created of the moon, planets and globular clusters are particularly impressive. But also with deep-sky objects such as the Orion Nebula the detection of details is much easier. At the same time this binoviewer is very easy to handle. Thanks to the newly patented optical system you can get into focus with any telescope. All you need is a pair of identical eyepieces to enjoy this dramatic and immersive viewing experience.How to use the BinoViewer? Since the BRESSER BinoViewer Deluxe does not require an additional light path (back focus), it can be used with any telescope - including Newtonians and short focus refracting telescopes, which traditionally suffered when using standard binoviewers. No light path corrector or similar accessory is necessary. If a standard 1.25'' eyepiece can be focused, the binoviewer will also work. The eyepiece focal length and field of view size of the eyepieces used are fully retained. As with binoculars one eyepiece is focused first using the telescope focuser. Then the second eyepiece can be brought into focus using the helical focuser on the binoviewer. The required interpupillary distance is then elegantly adjusted to a range of 58–74mm with the help of a linear sliding mechanism, with graduated marker, to help you find your ideal interocular setting quickly.  Self-centring helical eyepiece grips, rather than side-mounted thumbscrew eyepiece retainers are used, decreasing the chance of offsetting collimation of both eyepiece to each other.  The fact that this design of binoviewer uses a well-engineered linear slide mechanism to adjust interpupillary distance, rather than a cheaper-to-produce traditional hinged design also helps retention of collimation.Which objects can be observed with this accessory?Actually, all objects that were previously observed with the telescope in question, but only monocularly with one eye. Because there is no magnification factor at the binoviewer, even low magnifications can be achieved. This makes not only the moon, planets and globular clusters, but also the brighter deep-sky objects very interesting observation targets. The use of two eyes leads to a more relaxed view than using one eye alone.  Although true depth of field viewing at infinity is a little beyond most telescopes and binoviewers, users will note how the human brain attempts to impose depth of field ("3d-like") effects on stereo views through binoviewers.  The biggest difference that most observers comment upon when comparing views through binoviewers like these, as opposed to single monocular eyepiece views, is the extra detail that can be seen in most observable targets.  Relaxed viewing and extra detail in objects are the two main benefits of binoviewing, which the BRESSER Bino Viewer Deluxe 1.25'' delivers in abundance.Also ideal as an accessory for solar telescopesA very special application is the use of the BRESSER BinoViewer Deluxe in combination with all solar telescopes. The spherical shape of the sun with all its surface details is shown very impressively.  The depth of field effects of seeing filaments silhouetted against the solar surface are particularly enjoyable to observe.Important note: Do not use the BRESSER Binoviwer Deluxe without a suitable solar telescope or a safe solar filter in front of the telescopes objective lens . Otherwise, there is an acute risk of going blind.High-quality mechanics and materialsThe entire BRESSER BinoViewer Deluxe is made of high-quality materials. Except for the outer plastic covers all components are made of anodised aluminium. Particularly remarkable are the low-backlash sliding mechanism for adjusting the interpupillary distance and the precise rotary clamping of both eyepiece adapters. The wide clamping surface holds the eyepieces in place securely and also centres them automatically on the optical axis. The one-sided dioptric adjustment has a backlash-free helical drive and enables the finest corrections. For safe transport a high-quality hard-shell transport case is included in the scope of delivery.Which eyepieces can be used?All eyepieces with a 1.25'' barrel and a field stop of up to 22mm. Depending on the interpupillary distance the outer diameter of the eyepiece housing should not exceed a value of approximately 50 mm.Filter thread 1.25'' availableNo 2nd filter sets are necessary to operate the BRESSER Binocular Approach Deluxe. The desired colour or nebula filter can be screwed directly into the 1.25'' nosepiece. in this configuration, when changing the eyepieces to affect a change in magnification, no swapping of filters is necessary.  Unique mirror-lens system with Ohara (Japan) lanthanum glass material The BRESSER Binocular Viewer Deluxe is equipped with a unique mirror-lens system. This has the advantage of higher light transmission and less color aberration. The resulting image is simply brighter and sharper. To achieve this the exclusive Ohara (Japan) lanthanum glass material has been used and in addition all optical surfaces are equipped with a full multi-layer broadband coating. Finally the beam-splitting mirror has a 99% dielectric coating and completes the excellent optical design.FEATURESEnables binocular observations with all telescopesRelaxed and comfortable viewingThree-dimensional viewing experienceSuitable for all telescopes with 1.25'' eyepiece connectionNo additional light path requiredNo magnification factor at the binocular attachmentEven low magnifications with large fields of view are achievableFor observing moon, planets and deep sky objectsPrecise and robust mechanicsSliding mechanism to adjust the interpupillary distanceDioptric compensation via fine helical driveWide eyepiece rotation clamp with automatic centeringFilter thread 1.25'' (M28.5 x 0.6mm) availableLens and mirror design made of finest Ohara (Japan) lanthanum glass materialAdvanced broadband multilayer coating on all optical surfaces99 % dielectric-coated beam-splitting mirrorHigh-quality hard-shell carrying case includedWHAT'S INCLUDEDBino Viewer DeluxeDust capsCarrying case
