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.

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 optionsTwo black USB A sockets for normal charging and another orange USB A socket with QC3.0 standard for fast charging of newer generations of devices are available for powering your devices. An additional universal connection cable with a hollow DC plug 5.5/2.1 mm in diameter and 2.5 metres long, as well as 3 plug adapters (3.5/1.35 mm, 5.5/2.5 mm, 8.0/5.5/0.8 mm) 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 3100mA (3.1 amps). So 3000 : 3100 x 75 = 73 minutes. Dividing the result by 60 gives the charging time in hours: 1.2 hours.This means that an average smartphone can be fully charged in just about 1.2 hours with a 40-watt solar panel.   Carabiner hooks for attachment includedIn 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. 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.
