Warning notes
  • Check the solar filter before every solar observation and ensure that it is not damaged. Hold it against a strong light source to detect any possible cracks and/or holes. Do not use the telescope for solar observation, even if the solar filter is only slightly damaged. In this case, contact the manufacturer for the appropriate replacement parts.
  • Always use the included solar filter when observing the sun. Make sure it is correctly attached to the telescope according to the instructions. The use of the solar filter is only intended in connection with this telescope.
  • 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.
  • Check the secure fit of the solar filter before each solar observation. An accidental detachment from the objective opening can lead to immediate and permanent eye damage and blindness.
  • If the solar filter cannot be securely attached to the tube, improve the fit by placing several self-adhesive felt strips or similar between the solar filter and the objective opening. Never use the solar filter if it cannot be properly mounted on the telescope. In such a case, always contact our customer service first.
  • Be extremely cautious when observing the sun. A brief look through the unprotected optics will immediately cause severe eye damage, potentially leading to complete blindness.
  • Children should not look at the sun through the telescope, even with the filter properly installed. Never leave children unsupervised.
  • 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 observe the sun after eye surgeries or other eye conditions without prior medical consultation.
  • Wrinkles/creases in the film are normal and do not indicate a product defect.
  • Do not expose the device to high temperatures.
  • BATTERY WARNING AND SAFETY Safe handling and use of batteries and accumulators Read and follow these instructions before using the battery or accumulator. To the extent permitted by law, failure to comply with these warnings and instructions may result in any damage caused to your product not being covered by the warranty. In this document, the term "batteries" also includes accumulators. Follow these instructions to ensure optimal safety and performance: DO NOT use counterfeit batteries in products. Only use supplied batteries. Use the battery SOLELY for its intended purpose. Keep batteries out of the reach of children and pets. DO NOT use batteries that appear to be damaged, swollen, or modified. Do not use batteries that are leaking, emitting a smell, swollen, melted, or showing dents, rust, cracks, or scratches. The battery should NOT be disassembled, crushed, punctured, shredded, or otherwise tampered with. The battery should NOT be exposed to liquids.

BRESSER Lyra 70/900 EQ3 Refractor Telescope with Smartphone Adapter & Solar Filter
Unpack, set up, enjoy – with this complete telescope set you will soon begin your first exploration of the night sky. All the equipment for your new, exciting hobby is already included: the lens telescope with 70 mm aperture and 900 mm focal length, the equatorial mount, the tripod and a wide range of accessories for astronomical observations. Ideal for beginners: the system is very easy to handle and can even be used by children. Well-proven design for an easy beginning – the telescope With this set you'll start your voyage of discovery to the stars with a classic refracting telescope, a so-called achromatic refractor of the Fraunhofer type. The advantage of this particular design: even beginners as well as children can use it with ease. In addition, the Lyra refracting telescope impresses with good imaging properties due to its modern, precisely coated optics. If you compare this entry-level telescope to a corresponding astronomical telescope with a 60 mm aperture, you will notice: With its 70 mm aperture, the Lyra already collects 36 % more light. It also offers better resolution. In addition, 70 mm aperture and 900 mm focal length result in a very large focal ratio (ratio of aperture to focal length) of about 1 to 12.9 (F/12.9). The impressive result: a very sharp image with good contrast. Enjoy the view of our natural satellite, the Moon. Or take a look at the planets. Even the famous Pleiades sparkle captivatingly in your field of view. For the long focal length makes the telescope a specialist for observing the Moon, Sun, planets and open as well as globular clusters. And how big will these eye-catchers of the sky appear? Thanks to the 70 mm aperture, the resolution allows magnifications of up to 140x with really sharp images. Technically, much more would be possible – theoretically up to 675x using the included accessories. However, then the image sharpness could slowly decrease with increasing magnification. Of course – as with everything in astronomy – the prevailing conditions also play a role: So, how much you can actually magnify is determined not only by your telescope's performance but also by the air turbulence in the atmosphere (seeing conditions). Perfect foundation for your glimpse into space – mount and tripod Once you have found the ideal location for your astronomical telescope, you can quickly start exploring the sky. Simply mount the tube with the equatorial mount on the height-adjustable aluminium tripod. This special type of mount has the advantage of particularly convenient tracking: for this purpose, an axis is aligned parallel to the Earth's axis by pointing it approximately at Polaris during the so-called "alignment". Afterwards, the movement of the celestial bodies can be conveniently compensated for on this one axis rather than on both at the same time, as is the case with an azimuthal mount. In addition, the two flexible shafts with fine adjustment ensure the very precise and comfortable adjustment and tracking of the entry-level telescope. Always the right accessories at hand: the storage plate between the tripod legs provides space for eyepieces, barlow lens, solar filter etc.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! All-round equipment for astronomy newbies – the accessories Moon, planets or the Sun – with the extensive accessories you will get the best out of your astronomical telescope for any observation object. But initially, the LED viewfinder helps you find the nocturnal celestial bodies in the first place. To do this, the direction finder is installed and aligned parallel to the actual telescope. When you then look through it, a small red dot appears to hover in front of the sky. It shows you the spot at which the telescope is pointed. In this way, you precisely align the tube and easily find your objects before you gaze at them through the higher magnification of the telescope. Change of perspective for stargazers: using the two eyepieces you achieve different magnifications. They can be switched easily: With their standard socket diameter of 1.25 inches (31.7 mm), they are simply inserted into the eyepiece focuser of the entry-level telescope. Looking for even more detail? Then grab the 3x barlow lens and triple the magnification of the eyepieces. Comfortable observation at all times: a 90-degree star diagonal mirror is included. So, even if the telescope points vertically upwards into the sky, you can still look in comfortably from the side. For exciting discoveries during the day simply attach the safe solar filter to the telescope’s aperture. This way you can take a closer look at our own star and marvel at sunspots and granulation on the sun. CAUTION: Never point the telescope at the sun without the solar filter! Take the plunge into the fascinating world of astrophotography with the smartphone adapter. It allows you to use your smartphone as a camera on the telescope – and easily take exciting snapshots of your favourite celestial bodies such as the Moon or the Sun.

BRESSER Venus 76/700 AZ Reflector Telescope with Smartphone Adapter & Solar Filter
The BRESSER Venus 76/700 AZ reflecting telescope allows beginners to experience their very own stargazing hours quickly and easily. With the complete set, you are equipped with everything you need for your very own sky observations: an astronomical reflecting telescope with 76 mm aperture and 700 mm focal length, an azimuthal mount, a tripod as well as extensive accessories. And to guarantee a successful start in astronomy, the system is very easy to handle – the perfect first telescope for beginners! Established technology for your easy start – the telescope With this entry-level telescope, you will be able to admire the night sky through a classic Newtonian reflector. A little surprising for astronomy novices: with this particular type, you do not look in at the back of the telescope, but at the front and laterally. The advantage: even if the telescope aperture is directed vertically towards the sky, you can make your discoveries very comfortably. No need to bend down! In addition, the Newtonian reflector is very easy to use. The optics in this type of reflector telescopes are also impressive, because they are free of chromatic aberrations – resulting in good imaging properties at all times. A sharp image with good contrast – the Venus reflector telescope achieves this with its large focal ratio of about 1 to 9.2 (F/9.2 – calculated from 76 mm aperture and 700 mm focal length). Thanks to its long focal length, the telescope for beginners shows you the Moon, Sun, planets, open star clusters as well as globular clusters in a particularly impressive way. And all this at a magnification of up to 150x in really sharp images! Technically, you can magnify even higher – theoretically up to 525x while using the included accessories. However, as the magnification increases, the sharpness of the image may slowly decrease. Of course, how much you can magnify depends not only on the resolving power of your telescope. The air turbulence in the atmosphere (seeing conditions) also plays an important role. Note for nature lovers: If you choose a Newtonian telescope like the Venus 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. A good foundation for a successful start – mount and tripod The height-adjustable aluminium tripod and the azimuthal mount provide a firm footing and easy celestial navigation. Especially the azimuthal mount makes life easy for beginners, because it is very user-friendly: just like a typical photo tripod, you turn the telescope by hand to the left and right, up and down. This way, your favourite celestial objects quickly appear in your field of vision. Handy: to ensure that your astronomy accessories are always within reach, there is a storage plate between the tripod legs. Everything that goes with it – the accessories Out of the box straight to the fun of observing – with the complete astronomy set, you are quickly on your way to discovering the universe. The LED viewfinder helps you keep an eye on the sky. You just mount the direction finder parallel to the actual telescope and it projects a red dot onto a small ground-glass screen. This then appears to be hovering in front of the sky when you look through the viewfinder. And it does so at exactly the same spot that your telescope is pointed at. This way, the LED finder helps you to align the reflector telescope precisely and to find the celestial objects more easily. When it comes to the level of detail in your observations, the Venus beginner's reflector telescope gives you a choice: the two included eyepieces (4 mm and 20 mm) allow you two different magnifications. You want to get an even closer look? Then simply triple the magnification of the eyepieces with the 3x Barlow lens. In addition, the socket diameter of 31.7 mm (1.25 inch) complies with an international and manufacturer-independent standard. So you can easily expand your set – and with it your astronomical horizon. If you want to observe fascinating sights not only at night but also during the day, simply grab the solar filter. With it, you can safely admire spots and granulation on our nearest star – the Sun. CAUTION: Never point the telescope at the Sun without the solar filter! A new hobby leads to new impressions – and naturally you want to capture and share those. Therefore, you can easily use your mobile phone for your first steps into astrophotograpy with the smartphone adapter. Perfect for great snapshots of the Moon or the Sun, for example. Look forward to exciting astronomical discoveries by day and night – with the BRESSER Venus 76/700 AZ reflector telescope.

BRESSER Arcturus 60/700 AZ - Refractor Telescope with Hard-top Case
Open the case and you're ready to go: The BRESSER Arcturus 60/700 AZ lens telescope shows you the fascinating world of star clusters and planets. This complete set contains everything you need for your first steps into sky observation: an astronomical lens telescope with 60 mm aperture and 700 mm focal length, an azimuthal mount, a tripod and lots of accessories. The system is very easy to handle and therefore ideal for introducing children to astronomy as a hobby. And since there are so many beautiful things to discover on Earth as well, the telescope is suitable for observing nature and landscapes. Simply an astro-classic – the telescope With this classic lens telescope – a so-called Fraunhofer achromatic refractor – even beginners and children can easily gain new insights into the night sky. Thanks to the modern, precisely coated optics, the starter telescope offers good imaging properties. A sharp image with good contrast – this is ensured by the large focal ratio of about 1 to 11.7 (F/11.7), which results from the ratio of the 60 mm aperture to the 700 mm focal length. Perfect for exploring our Moon, the planets, but also open star clusters and globular clusters. And what about the magnification? The 60 mm aperture provides a resolving power that easily allows magnifications up to about 120x with really sharp images. Technically, even more is possible with this beginner’s telescope – up to 175x with the included accessories. However, as the magnification increases, the image can become more and more blurred. How much magnification is actually possible depends not only on the telescope, but also on the air turbulence in the atmosphere (seeing conditions). The foundation for moving impressions – mount and tripod For your nighttime observations, attach your telescope to the height-adjustable aluminium tripod with azimuthal mount. Thanks to its extremely easy operation, you can enjoy effortless astronomical explorations with this azimuthal mount. Just like with a normal photo tripod, you simply turn the starter telescope by hand up and down, to the left and right. To ensure that your eyepieces, compass, star map etc. are always within reach, simply place your accessories on the practical storage plate located between the tripod legs. Everything for a good start in astronomy – the accessories In the sturdy hard-top case, in which you can store the beginner's telescope perfectly and take it safely with you on your travels, you will also find lots of accessories. The 5x24 finder is a small miniature telescope that you simply mount parallel to the actual telescope. With its weak 5x magnification and integrated crosshair, it helps you keep track of the starry sky. So it allows you to easily find celestial objects and precisely align the telescope – before you then enjoy the view with the higher magnification. And how high the magnification is depends on which of the three included eyepieces (4 mm; 12.5 mm; 20 mm) you are currently using. To change the magnification, simply insert another one into the telescope's focuser. If at some point you want to change your field of view with additional eyepieces: no problem! The 1.25 inch (31.7 mm) socket diameter complies with an international and cross-manufacturer standard, so you can combine a wide range of optional eyepieces with your telescope. For a comfortable view at any time, you will also find a 90-degree diagonal mirror in the scope of delivery. Otherwise, you would have to lie down under the starter telescope in order to achieve good observation results when the optics are pointed upwards into the sky. Instead, you simply look in comfortably from the side. In addition to the night sky, the Earth also offers many captivating sights. That's why the 1.5x erecting lens turns the image the right side around, so that you can devote your entry-level telescope to observing nature and landscapes during day. However, because orientation in the night sky is not as easy as on our daytime planet, a compass and star map are included in the set. This way you always know where to look and what you will see there.

BRESSER Polaris-I 102/460 EQ3 Refractor Telescope with Smartphone Adapter & Solar Filter
The view of the night sky holds countless fascinating sights in store for us. The BRESSER Polaris-I 102/460 EQ3 lens telescope comes with everything you need for a quick and easy start in astronomy: an astronomical lens telescope with 102 mm aperture and 460 mm focal length, an equatorial mount, a tripod and a wide range of accessories. The system is extremely easy to handle - perfect for newcomers to the exciting hobby of astronomy. Moreover, due to its compact dimensions, the entry-level telescope is ideally suited as a travel telescope. So find the perfect observation site and enjoy an exciting ''walk'' through the Milky Way. Classic telescope for a new generation of stargazers – the telescope Children and beginners in particular benefit from the classic design of this lens telescope, which is also called an achromatic refractor according to Fraunhofer. This is mainly due to its easy handling – ideal for your fist steps in celestial observation. The entry-level telescope owes its good imaging properties to the optics’ modern, precise coating. The 102 mm aperture already collects a lot of light from the celestial objects. But it is due to the very short focal ratio (ratio of 102 mm aperture and 460 mm focal length) of about 1 to 4.5 (F/4.5) that you can enjoy an extra-bright image. Another advantage of the combination of short focal length and fast focal ratio: the beginner's telescope shows you the details in the Milky Way and extended gas nebulae such as the North America Nebula NGC 7000 particularly impressively. This makes a ''trip'' through the Milky Way with low magnification so much fun. However, the telescope will also give you a lot of pleasure while travelling on Earth, because it is very compact and thus perfect as a travel telescope. And what about the magnification? Here, too, the aperture of 102 mm shows its effect: It gives the telescope a resolving power that easily allows magnifications of up to about 200x with sharp images. From a purely technical point of view, this is by no means the limit – with the included accessories, you can theoretically magnify up to 345x. The image sharpness can slowly decrease with increasing magnification, though. However, the degree of magnification achievable does not only depend on your telescope. The air turbulence in the atmosphere (seeing conditions) also influences your astronomical observations. Set up, align, start marvelling – mount and tripod Found the perfect location for your observations? Then attach the telescope tube to the eight-adjustable aluminium tripod with equatorial mount and off you go. The special advantage of equatorial mounts: Unlike with an azimuthal mount, you don't need to move both axes at the same time. Instead, you align one axis parallel to the Earth's axis by pointing it approximately at the polar star. Then you simply track the movement of the celestial bodies just on this one axis. Because you move the axes via two flexible shafts with fine adjustment, you can adjust and track the beginner's telescope very precisely and comfortably. And for quick access to all your accessories, simply place them 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! Must-haves for star observation – the accessories In order for you to start stargazing right away, the astronomy set comes with many accessories. With the LED viewfinder, you can easily keep track of the sky. Just install the viewfinder parallel to the actual telescope and it projects a red dot onto a small ground-glass screen. When you look through it, this dot appears to be floating in front of the sky. Not just anywhere, but exactly at the point at which your telescope aperture is currently pointing. This allows you to align your telescope more precisely and find the celestial objects you have chosen for your night-time exploration much more easily. As with everything else, a change of perspective is always fun. Therefore, the two eyepieces (4 mm and 20 mm) allow you to view the objects in different magnifications – and thus enjoy completely different views. You want to see even more details? Then triple the magnification of the eyepieces with the 3x Barlow lens. The telescope for beginners is also flexible when it comes to upgrades: the diameter of the sockets is 31.7 mm (1.25 inches), which is an international standard that applies to all manufacturers. So you can choose from a large variety of additionally available eyepieces. In order for you to explore the universe with ease, the 90-degree star diagonal mirror always offers a comfortable view into the beginner’s telescope. Even if the telescope is pointed vertically upwards into the sky, you simply look in from the side – and just enjoy the view. But it is not only at night that the sky attracts our attention with spectacular highlights. In the daytime sky, our nearest star is particularly worth seeing. You can observe it completely safely using the solar filter. You will be amazed once you take a closer look at the sunspots and the granulation on the Sun. CAUTION: Never point the telescope at the Sun without the solar filter! Capture your favourite moments of sky observation. You can easily take your first steps in astrophotography by using the smartphone camera adapter – for impressive snapshots of the Sun and Moon, for example. Set off on your very own voyage of discovery to the Sun, Moon and through the Milky Way – with the BRESSER Polaris-I 102/460 EQ3 refractor telescope.

BRESSER JUNIOR Refractor Telescope 70/900 EL
Observing the stars like a professional - very easy with the BRESSER JUNIOR refractor telescope 70/700 EL. It is a complete system for the exploration of the wonders of the universe, consisting of telescope, mount, tripod and all accessories needed. With an aperture of 70 mm it reveils already many details of celestial objects. The mount can not only swing the telescope left / right and up / down, it can also be used in a so-called equatorial mode, as scientists do in their observatories (see further under Special features). An additional finder scope mounted on the telescope is useful for locating celestial objects. With the erecting lens many exciting things in the environment can also be seen during daytime. With the height-adjustable tripod, the telescope can each be brought to an optimal height for large or small observers. The supplied diagonal mirror ensures a comfortable viewing. At night the moon and planets may like Saturn and Jupiter can be explored. But thanks to the 70 mm wide aperture of the telescope also many celestial objects outside our solar system are within the reach of this telescope. Star clusters many light years away and nebula impress young and old stargazers. SPECIAL FEATURESMounting with wedge: At first glance, the NG mount of the refractor telescope 90/700 NG is a very ordinary azimuth mount: an axis for left / right and one for up / down, as we know it from normal camera tripods. This mode makes sense especially with observations during the day. With the built-in wedge it can be tilted, so the whole mount can be converted to an equatorial mount for astronomy with a single operation. For use of the equatorial mount an axis is aligned with the North Star. When tracking a celestial object only a single axis needs to be moved, which clearly is a relief compared to tracking an object on the night sky with mounts that only have left / right and up / down axis. FEATURESideal beginner's setsuitable for lunar, planetary and nature observationsmount can be used in two ways: alt-azimuth and equatorialSCOPE OF DELIVERYrefractor telescope 70/900three eyepieces: 4 mm (225x), 12 mm (75x) and 20 mm (45x)heigth-adjustable aluminium tripod with accessory tray1.5x errecting lens for a laterally correct and upright imageNG mountfinderscope 6 x 25astronomy software for PC90° diagonal mirror
