Please note that this astronomy book for beginners is only available in German.

Self-sufficient travel with the BRESSER solar charger Whether camping, sailing, trekking or swimming at the nearest lake – anyone who enjoys being outdoors for long periods of time does not want to do without their smartphone, tablet, powerbank, etc. But one question quickly arises: where can I find the nearest power socket? After all, every battery runs out and our practical everyday helpers can't manage without electricity. With the ultra-compact BRESSER solar charger, you simply use the power of the sun to charge your devices. The environmentally friendly solar energy is free of charge – and you remain independent of the power grid! Simply open it up, put it down and immediately produce green solar powerThe handling is very simple: unfold the solar panel and align it as perpendicularly as possible to the sun. Then connect the device to be charged to the solar charger, either with a suitable USB cable (not included) or with the included DC connection cable. The charging process begins immediately. Which devices can the solar panel charge? The solar charger gets all devices with a USB power supply connection or the above-mentioned DC power plug connection up and running again in no time – e.g. smartphones, tablets, power banks, portable playstations, MP4 players, GPS devices and Bluetooth headphones. For charging large power stations, we recommend the more powerful BRESSER solar panels with at least 60 watts output power – see art. no. 3810050, 3810060, 3810070.Universal charger with flexible connection optionsOne USB-A connection socket is available for powering your devices. There is also an additional universal connection socket for DC bar plugs with a diameter of 5.5/2.1 mm. A universal connection cable with a 5.5/2.1mm DC bar plug on both sides and a length of 2 metres, as well as 3 plug adapters (3.5/1.35mm, 5.5/2.5mm, 8.0/5.5/0.8mm) are included in the scope of delivery. The polarity of the connectors is as follows: Inner contact = positive (+), outer contact = negative (-). How long does it take to charge a battery?Most modern devices with built-in batteries indicate the current charging status of the battery on a display or status LEDs. The charging process is also automatically terminated by the internal charger of the smartphone or tablet, etc., as soon as the battery is full.Nevertheless, it is helpful to know how long a full charge theoretically takes with an empty battery. This is the only way to choose the right solar panel model for the requirements of the devices you want to charge.Here is a short calculation: Divide the capacity of the battery (mAh) by the charging current of the charger (mA) and multiply this by a factor of 75. This then gives you the approximate charging time in minutes that is required to fully charge the battery at 100% sunshine duration.Example: A battery with a capacity of 3000mAh (3.0 Ah) and a charging current via 5 volt USB connection of 2400mA (2.4 amps). So 3000 : 2400 x 75 = 94 minutes. Dividing the result by 60 gives the charging time in hours: 1.6 hours.This means that an average smartphone can be fully charged in just about 1.6 hours with a 21-watt solar panel. Carabiner hook for attachment included In order to attach the solar panel securely to an object and align it perfectly with the sun, 4 sturdy snap hooks are included in the scope of delivery. Simply connect them to the riveted ring eyelets of the solar panel and use them to hang the solar charger stably, e.g. on a tent loop, a fence or other suitable holding points. If you attach it to your backpack, you can even use the time during a hike for charging. Innovative solar cell technology with high efficiency Monocrystalline silicium cells ensure high efficiency and the fastest possible charging of the device batteries. This means maximum electricity yield per solar surface. As a result, you benefit from relatively high charging currents and short charging times with a compact design.Easy transportThanks to the modern and flat design, you can easily fold the individual segments of the solar panel into a small bag and stow it in your luggage while saving space. Always ready for the next spontaneous use.Robust, dust- and water-repellent materials The durable Cordura fabric is extremely tear-resistant but still flexible. It protects the valuable solar panel from damage and provides the necessary stability during use. The solar panel is dust- and water-repellent, it withstands most weather conditions and is your ideal companion for almost all outdoor activities. Nevertheless, the solar panel should not be exposed to direct rain or extreme humidity.IMPORTANT NOTESThe solar panel does not have an integrated charger or charge controller. Therefore, it is not suitable for directly charging loose battery cells or lead batteries. It is only suitable for smartphones, tablets and power banks, for example, because they always have built-in internal chargers.The solar panel does not have its own battery, but serves exclusively as a power source in sunshine for charging electronic devices.When connecting the devices to be charged via the DC bar plug, always ensure the required voltage and correct polarity. Otherwise, damage may occur to the electronics of the solar panel and the devices to be charged.Do not leave the solar panel outdoors at night with high humidity or in the rain. This could damage the internal electronics.

This reflecting telescope shows not only the big planets, but also bright deep-sky objects when you are observing under dark skies. Fully equipped, and with a mount that is easy to use, this telescope is ideal for a beginner that has no astronomical knowledge, but wants to immerse him or herself in space. Explore the moons and cloud bands of Jupiter or the majestic rings of Saturn, or find other galaxies, star clusters and nebula on a moonless night. 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 refractor (lens) telescopes for landscape and nature observing.

The 90/900 refractor telescope is a classic achromatic refractor and can be used for either astronomy or nature observations (e.g. of wild animals). The long focal length (900 mm) makes the telescope a specialist for observing the Moon, planets and bright objects outside our solar system. Saturn's majestic rings and giant storms on Jupiter can be seen, as well as the brighter emission nebulae, galaxies and star clusters if you observe on a dark, moonless night away from city lights. The sturdy equatorial mount can be aligned to the Pole Star, Polaris, and makes tracking objects by hand child's play.Three eyepieces, a 20mm, 12.5mm and 4mm, giving 45x, 72x and 225x magnification respectively, are included and also a 3x Barlow lens and Moon filter as standard.  A red LED reflex finder, once aligned to the telescope's main optical axis, will help you find your way to a huge array of potential targets for observation in the night time sky.The EQ3 mount is provided with slow motion flexible cables to help you follow objects accurately and compensate for the effects of the Earth's rotation.  The mount can also be upgraded to a simple RA motor tracking kit with additional purchase.FEATURESOptical System: Achromatic RefractorLens diameter: 90mmFocal length: 900mmMagnification: 45x-675xMount: EQ3, equatorialTripod: Aluminium with accessory traySCOPE OF DELIVERYOptical TubeMountAluminium tripodEyepieces 31.7mm (1.25"): H-20mm, H-12mm, SR-4mm3x Barlow LensMoon filterLED viewfinderStar map

The telescope arrives completely assembled - observation can start immediately. It was never easier for the public to observe the night sky and the sun so easily, cheap and - last but not least - safe. The solar filter that was especially designed for this telescope makes it possible. It contains a special foil that protects the eye against all kinds of solar radiation during observations: infrared, ultraviolet and visible light is dampened to a safe level. Only a safe amount of the visible spectrum can pass the filter and creates a wonderful solar image in the eyepiece. The safety feature of this filter was checked by an independent quality assurance company. Do you want to capture what you see? With the included smartphone holder bracket, you can use your smartphone to easily take colour pictures of celestial objects - like through a telephoto lens! But the BRESSER Solarix 114/500 is of course also ready to be used for observing astronomical objects in the night sky. The featured accessories are everything you need for an immediate start. The newtonian reflector is equipped with a extensive manual and set up in almost no time. The telescope arrives completely assembled - observation can start immediately. 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.

Set off on your personal journey to the stars with the BRESSER Sirius 70/900 AZ lens telescope. The complete astronomy set already includes everything you need to start observing the sky: the astronomical lens telescope with 70 mm aperture and 900 mm focal length, the azimuthal mount, the tripod and a wide range of accessories for fascinating discoveries. At the same time, it is very easy to operate - ideal to amaze even children with a view of the night sky. Simply a stargazing classic - the telescope With this lens telescope - a so-called Fraunhofer achromatic refractor - even total astro-beginners and children can easily explore the secrets of our night sky. Because this classic design impresses with its special user-friendliness and easy handling. To ensure that you enjoy good imaging properties when looking at the Moon, Sun, planets and star clusters, the entry-level telescope has been equipped with modern, precisely coated optics. The 70 mm aperture collects a total of 100 times more light than the human eye. And it is also convincing compared to a comparable 60 mm telescope: the light gathering capacity is 36 % higher and the resolving power is also better. Thus, with the 70 mm lens telescope, significantly more details are visible at the same magnification, e.g. on Saturn's rings or the two main cloud bands of Jupiter. But how big do the celestial objects appear then? The resolution of the 70 mm lens lets you enjoy really sharp images at magnifications up to about 140x. For comparison: with a 60 mm aperture, this is only possible up to 120x. Technically, of course, the starter telescope can do even more - theoretically up to 675x with the included accessories. However, with increasing magnification, the image can slowly become more and more blurred. And how big you can really see the planets, star clusters and co. depends not only on the telescope. Another important factor: the air turbulence in the atmosphere (seeing conditions). A sharp image with good contrast - this is what the starter telescope achieves with its large focal ratio of about 1 to 12.9 (F/12.9), which is calculated from the ratio of the 70 mm aperture to the 900 mm focal length. And you will see: Due to the long focal length, especially the Sun, Moon, planets, open star clusters and globular clusters become absolute eye-catchers. Solid base for your stargazing hours - mount and tripod Found the ideal location for your nocturnal explorations? Then attach the telescope tube to the height-adjustable aluminium tripod with azimuthal mount. And this azimuthal mount is particularly compelling due to one quality: operation is really child's play. Simply swing the telescope by hand to the left or right, up or down, as with a common photo tripod. This way you can quickly move your gaze from one celestial highlight to the next. And where are the accessories? Simply place them on the storage plate between the tripod legs. This way, eyepieces, solar filter and co. stay always within reach. All the trimmings - the accessories The beginner’s telescope comes with everything you need for a quick start in stargazing. When searching for celestial bodies worth seeing, take your first look through the included LED viewfinder. Because the direction finder helps you to align the telescope precisely and find astronomical objects. It works like this: The LED finder is mounted in parallel on the telescope tube. It projects a red dot onto a small ground-glass screen that appears to float in front of the sky when you look through it. And that is exactly where the aperture of your telescope points. This way, you can always keep an overview of the night sky - before focusing your attention on the details through the magnification of the telescope. And you decide how high this magnification is by choosing the eyepiece. You will be amazed: the two eyepieces included in the set (4 mm, 20 mm) allow you to admire completely different images of the same object. If you one day want a change of perspective, you can expand your astronomy set with a large selection of eyepieces. For this purpose, the socket diameter is 1.25 inches (31.7 mm), which corresponds to an international, manufacturer-independent standard. You like what you see, but would love more detail? Then simply insert the 3x Barlow lens between the telescope and the eyepiece. And you have tripled the magnification of the eyepiece! Observation comfort and a pleasant view - this is what the 90-degree star diagonal mirror is made for. Even if your starter telescope is pointed vertically into the sky, you don't need to lie down underneath it to see anything. Instead, simply look in comfortably from the side and enjoy the view. But it's not only at night that we should look skywards. For only during the day you can see a very special star: our Sun. So put the solar filter in front of the lens and safely look at sunspots and granulation on the Sun. CAUTION: Never point the telescope at the Sun without the solar filter! Would you like to share your discoveries with friends and family? Then take your first steps in astrophotography right away - and those are done in no time with the smartphone camera adapter for your beginner's telescope. The Moon, Sun, planets, open star clusters and globular clusters always make a good picture. Discover what our night sky has to offer with the BRESSER Sirius 70/900 AZ refracting telescope.

NEW - now including a high-quality aperture Solar-filter for safe observation of sunspots, eclipses and planet transits. The computer-controlled Refractor Telescope BRESSER Automatik 80/400 is a wide-field-lens telescope that goes with you almost anywhere, due to its compact design. The telescope is the ideal choice for beginners and is also perfect for travelling. Take this computerized telescope with you to your favourite observation place, when you're hiking, camping or on vacation. It may be small, but it still includes an easy-to-use go-to system. The BRESSER Automatik 80/400 can be operated on a desk or with the included tripod. The computer control allows for an easy alignment of the telescope with the night sky and can navigate to interesting celestial objects automatically by a push of a button. Over 270,000 well known astronomical objects are still stored in its database of the computer control. You can sit back and only need to focus on one thing: the view of the vast, starry firmament! It will show numerous craters on the moon, the cloud belts on Jupiter or Saturn's rings. These is just the beginning of what can be seen with this telescope.

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.

Do you already own a photo camera and would like to create impressive pictures of the night sky with the help of the long exposure or even make time-lapse pictures with little effort? The BRESSER StarTracker Astronomical Photo Mount Kit is the ideal base. Not only for beginners in astrophotography, this mount is particularly well suited, but also the experts swear by a compact and easy-to-use mount to automatically compensate for the natural rotation of the earth. The built-in tracking motor rotates the saddle-mounted camera precisely against the earth's rotation and thus the stars remain in pinpoint shape even with long exposures. This set contains all the components required for a quick and comfortable entry into the world of astrophotography with the exception of a camera and objective lens: A stable BRESSER tripod TP-100 DX with carrying bag, the BRESSER Micro Motion Head MH-100 (polar-wedge), the BRESSER Polar Finder Scope for StarTracker PM-100 and of course the BRESSER StarTracker astrophoto mount PM-100 with ball head.Which cameras are basically suitable for use with the BRESSER photo mount? All cameras with 1/4'' (6.3mm) tripod connection thread and bulb length B for long exposure are suitable. The BRESSER StarTracker Astronomical Photo Mount PM-100 is designed for a camera with lens of max. 2.0 kg total weight to carry and track in polar mode. In Azimut mode also a camera weight up to 5.0kg is possible.  Large aperture, wide-angle lenses are ideal for the beginning, because the requirements for tracking accuracy accumulate with increasing focal length and exposure time. Thus, a shot with wide-angle lens can be exposed for up to several minutes and the stars remain punctiform without problems. For example, with a 200mm telephoto lens the polar alignment of the photo mount must be exactly right. But thanks to the delievered optical Polar Finder Scope, this is done quickly. After setting up the light and compact StarTracker Photo Mount, simply set the approximate latitude (pole height) and aim Polaris through the integrated Polar Finder Scope. Then mount the camera with the photo lens using the quick-release plate on the supplied ball head. With the ball head, the camera can be aligned and determined at any time on any section of the sky. As soon as the tracking motor is switched on, long-time exposure can be started immediately. This does not even take 5 minutes ... The tracking is carried out by a precise stepper motor, which can be controlled by an easy digital setup on LCD screen. Low power consumption allows up to 20 hours of operation with just one battery charge or simply use the micro USB port for an unlimited power supply. Typically achievable exposure times with good tracking accuracy are: 16mm wide-angle lens: 5 minutes (300 sec.) , 100mm telephoto lens: 1 minute (60 sec.) FEATURES StarTracker Astronomical Photo Mount Kit Equatorial StarTracker Photo-MountAutomatic siderial tracking against the Earth rotation  Different tracking speed setting possible Suitable for northern and southern henisphere Time lapse: from 15 minutes to 48 hours Ballhead with quick release saddle plate and 1/4'' Photo thread for Kamera mountingPhoto-Mount with 1/4'' threaded bolt for ballhead mounting Additional quick release coupling for ball head removal High precision stepper motor with helical gear for accurate tracking Clear LCD screen and easy setup menu Battery operation 4 x AA batteries or mico USB (optional acc.)  Battery life: up to 20 hours Weight Photo-Mont: 0.63kgTransport weight incl. complete accessories: 3.6 kg Adjustment height mount with tripod: 80-155cm Tripod transport dimensions: 60x10x10cm; tripod weight: 2,1 kg Load capacity of Photo-Mount: up to 2.0kg/5.0kg (EQ/AZ) SCOPE OF DELIVERY BRESSER StarTracker astronomical Photo-Mount PM-100BRESSER Ballhead with quick release saddle plateBRESSER Polar Finder Scope for StarTracker PM-100BRESSER Micro Motion Head MH-100 (Polar-Wedge)BRESSER Tripod TP-100 DX with carry bag User manual
