Explore hidden worlds through your own eyes – with the BRESSER Pollux-I telescope starter set for budding amateur astronomers, you can go on your own journey of discovery in outer space. Everything you need is already included: the astronomical reflector telescope with 150 mm aperture and 750 mm focal length, the equatorial mount, the tripod and a wide range of accessories for astronomical observations. Perfect for getting started quickly: the system is very easy to use. In addition, the entry-level telescope impresses with its versatility: you can observe the Moon and planets as well as star clusters, gas nebulae and even galaxies through the high-quality optics. Due to the parabolic primary mirror the image delights with impressive sharpness and high contrast. In addition, the 2-inch focuser allows for the use of high-quality eyepieces. Perfect conditions for fascinating sights of the night sky! Time-proven optics for your first astro-steps – the telescope By choosing the Pollux-I, you’ll start your journey to the stars with a classic Newtonian reflector telescope. Beginners are often surprised by the fact that with telescopes of this type you don't look in at the back of the tube, but at the front and laterally. This gives you the advantage of always being able to look into the telescope in a comfortable posture, even when it's pointed vertically upwards at the sky. In addition, these reflector telescopes offer optics that are absolutely free of chromatic aberrations and thus provide good imaging properties. The large aperture of 150 mm collects a lot of light from the celestial objects. In addition, 150 mm aperture and 750 mm focal length result in a short focal ratio (ratio of aperture to focal length) of 1 to 5 (F/5). On the one hand, this makes the telescope fast and provide a bright image. On the other hand, high magnifications can be achieved. This combination makes the entry-level telescope so versatile. In addition, the Pollux-I is equipped with a parabolic primary mirror. The remarkable effect of this special mirror shape: you enjoy excellent imaging properties at all magnification levels. So you can look forward to the complete range of celestial highlights. At low to medium magnification, you can admire deep-sky objects such as open star clusters, globular clusters, gas nebulae and even galaxies such as the pair of galaxies M65 and M66 in the constellation Leo. And at high magnifications, observing the planets or details on the Moon is an absolute pleasure. You can get really close to your favourite objects: The aperture of 150 mm achieves a resolving power that allows magnifications of up to about 300x with sharp images. Technically, even higher magnifications are possible, theoretically up to 562.5x using the included accessories. However, with increasing magnification, the sharpness of the image can slowly decrease. In addition, the prevailing conditions always make a difference: How highly you can magnify always depends not only on the power of the telescope but also on the air turbulence in the atmosphere (seeing conditions). The telescope also impresses with its flexibility in terms of eyepiece compatibility: it comes with a 2-inch focuser (focuser extension) and an adapter from 2 inch to 1.25 inch. This enables you to use eyepieces with 1.25-inch sockets (about 31.7 mm) as well as eyepieces with the larger 2-inch sockets (about 50.8 mm) with large fields of view. Note for nature lovers: If you choose a Newtonian telescope like the Pollux-I reflector telescope, you can look forward to a specialist in astronomical observation. However, the image is always displayed laterally reversed as well as upside down, which makes no difference when observing the sky. However, this type of telescope is less suitable for nature and landscape observation during the day. Would you like to use your new telescope for exciting nature discoveries as well? Then we recommend that you choose one of the BRESSER refractor telescopes. Perfect foundation for fascinating discoveries – mount and tripod Your beginner's telescope is securely held by the height-adjustable aluminium tripod with equatorial mount. The special feature of this mount, also known as a parallactic mount: in contrast to azimuthal models, the movement of the celestial bodies is only compensated for on one axis instead of two. For this purpose, you simply align one axis parallel to the Earth's axis by pointing it approximately at Polaris. For precise and comfortable alignment and tracking of the entry-level telescope, the Pollux-I comes equipped with two flexible shafts with fine adjustment. And to ensure that the interchangeable eyepieces, barlow lens etc. always remain within reach, they can be stored on the tray between the tripod legs.Keep track of things automatically: For this telescope’s equatorial EQ-3 mount, the tracking motor with item number 4951400 is available as an optional accessory. This eliminates the need to manually track a celestial object set in the telescope. When this motor is installed at the mount, it automatically tracks the celestial object, keeping it in the field of view of the eyepiece. This makes observing the night sky even more comfortable! Well equipped for the ideal start – the accessories Your entry-level telescope comes with a wide range of astronomy accessories so that you can start to be amazed right away. For example, the LED viewfinder helps you align the telescope and find celestial objects. Installed in parallel on the telescope, this direction finder shows you a red dot when you look through it. It appears to hover in front of the sky and thereby shows you where the telescope is pointing. Varying view of the sky: With the two eyepieces with 1.25-inch sockets (31.7 mm), you can admire your astronomical discoveries at different magnifications. The 3x barlow lens already included in the set triples the magnification of the eyepiece you are using. Enjoy safe observations of our Sun with the included solar filter. This way you can easily take a closer look at sunspots and granulation on our own star. CAUTION: Never point the telescope at the Sun without the solar filter! Astrophotography for beginners: with the smartphone adapter, you can use your mobile phone as a camera on the telescope. This way you will quickly impress friends and relatives with your own first snapshots e. g. of the Moon or the Sun. FEATURES Reflector telescope with 150 mm aperture and 750 mm focal length Reflector type Newton with parabolic primary mirror Very well suited for observing the Sun, Moon and planets as well as star clusters, gas nebulae and galaxies Height-adjustable tripod with equatorial EQ3 mount Precise movement through flexible shafts and fine adjustment in both axes Easy to use, very good for beginners Focal ratio F/5, thus very suitable for many celestial objects 2-inch (50.8 mm) focuser with adapter to 1.25-inch (31.7 mm) Two eyepieces and one barlow lens with 1.25-inch (31.7 mm) sockets for different magnifications Safe solar observation with the included solar filter First steps in astrophotography with smartphone camera adapter SCOPE OF DELIVERY Telescope Aluminium tripod Equatorial EQ3 mount Adapter from 2 inch to 1.25 inch Eyepieces: 4 mm and 20 mm (1.25-inch sockets) Barlow lens 3x (1.25-inch socket) LED illuminated dot finder Solar filter Smartphone camera adapter Accessory tray Astronomy software as download Instruction manual

One eyepiece for every occasion The BRESSER zoom eyepiece covers the large focal length range from 8 to 24 mm. These are also the focal lengths most frequently used with most telescopes. Especially for instant observations, where you don't want to pack a whole suitcase full of eyepieces, the zoom eyepiece is a good choice. Always the ideal magnification on hand A quick turn and the ideal magnification for you is set. The adjustment is stepless from 8 to 24 mm focal length. This eliminates the need to always change eyepieces. Comfortable viewing The BRESSER zoom eyepiece offers a large comfortable eye relief of 20 mm to the eyepiece lens (LER = long eye relief). This means comfortable viewing even during longer observation, an important criterion especially for people with glasses. The rubber eyecup can also be individually adjusted by a twist and turn movement. Apparent field of view is 40 up to 56 degrees which offers a good overview. Advanced optical design To achieve the best possible image over the entire focal length range, a sophisticated optical design with 8 lenses in 5 groups is used. The full multi-coating on all lens surfaces also guarantees maximum light transmission. To effectively suppress unwanted reflections, all lenses are carefully blackened at the edges. Thus, the image produced offers the maximum possible contrast and image brightness. Compact and solid design The BRESSER zoom eyepiece is made entirely of black anodised aluminium. It has an extremely solid and high-quality material appearance and is long-lived even with extensive use. The precise zoom mechanism can be operated safely through the ribbed metal adjustment ring.

Large binoculars with 70 mm ED glass objective lensesObserve the beauty of the starry sky at night and distant objects in nature during the day. By customer request, we have succeeded in producing a new edition of these legendary binoculars. The ED glass lenses guarantee enormously high sharpness, contrast and colour purity even during the day. Globular clusters, luminous 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, aircrafts and animals can be seen in detail at long distances. With the binoculars of the Vixen BT series, you can bring everything up close. The large, fast ED lenses in combination with the ultra modern magnesium fluorite coatings on all lens surfaces enable maximum light transmission. Thus, these binoculars produce bright, sharp and high-contrast images even at night and dusk, allowing for a particularly aesthetic viewing pleasure.Comfortable travel binoculars can also be used with photo tripodsThe comfortable 45-degree viewer enables comfortable viewing even when the binoculars are tilted towards the zenith. The BT-ED70S-A large binoculars are 4 kg light and particularly portable. An attached metal carrying handle ensures easy transport and a secure grip during tripod mounting. The binoculars have a standard Vixen dovetail rail as well as a standard 1/4 and 3/8 inch photo tripod thread. They can therefore be used on almost all common photo tripods and telescope mounts.The ideal binocular mountHowever, we recommend the Vixen HF2 fork mount for mounting. Thanks to its sophisticated design and precision mechanics, it offers perfect viewing comfort and practically zero vibrations. Especially for astronomical observations, a solid mount with tripod is one of the most important accessories. This guarantees observation without shaking and allows you to see even the finest details.Interchangeable 1.25-inch eyepiecesStay flexible and use your favourite eyepieces and ideal magnification. The BT-ED70S-A has standardised 1.25-inch eyepiece holders, allowing you to change eyepieces at any time.Which eyepieces can be used?All eyepieces with a 1.25'' barrel. Eyepieces with focal lengths of 8 to 26 mm are particularly recommended. The magnification can thus be varied from approx. 15x to 50x (focal length of binoculars : focal length of eyepiece = magnification). The eyepieces are held in the binoculars by a precise brass ring clamp and guarantee a tilt-free position. Depending on the interpupillary distance, the outer diameter of the eyepiece housing should not exceed a value of approx. 50 mm. Of course, two identical eyepieces of the same series should always be used.Use of colour and nebula filters for astronomical observationsIncrease the contrast and visibility of objects and details by screwing the appropriate filters directly into the thread of the eyepiece sleeves. Of course, colour and nebula filters must always be used in pairs. All EXPLORE SCIENTIFIC screw-in filters with 1.25''/31.7 mm diameter are suitable (see Art. No. 03102xx).Comfortable 45-degree viewer and single focusingThe 45-degree viewer enables a relaxed observation position even when the binoculars are heavily tilted. The individual interpupillary distance can also be adjusted within a range of 58 to 102 mm. The fine helical focusing system makes precise focusing simple and effortless.Retractable dewcapsThe integrated dew caps can be pulled out in high humidity and cold conditions.
