Warning notes
  • General safety instructions DANGER Risk of eye injuries! Never look directly at the sun or near the sun through this device. There is a risk of blindness! Children should only use the device under supervision. Keep packaging materials (plastic bags, rubber bands, etc.) away from children! There is a risk of suffocation! FIRE HAZARD! Do not expose the device especially the lenses to direct sunlight! The light concentration could cause fires. RISK of material damage! Do not dismantle the device! In case of a defect, please contact your dealer. They will contact the service center and may send the device in for repair. Do not expose the device to temperatures above 60°C!
  • 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.
  • 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 expose the device to high temperatures.

BRESSER Pollux-II 150/1400 EQ3 Reflector Telescope with Smartphone Adapter & Solar Filter
Explore the beauties of the night sky with this complete telescope set. Everything is included so that you can get started immediately with the fascinating hobby of astronomy: the astronomical reflector telescope with 150 mm aperture and 1,400 mm focal length, the equatorial mount, the tripod and extensive accessories for exciting observations. Especially important for beginners: the system is very easy to use. Particularly the Moon, the planets and the Sun appear impressive through the Pollux-II. Powerful performance for your first celestial observations – the telescope Take your first steps in astronomy with this classic reflector telescope of the "Newton" type. Because it is equipped with an additional lens inside the focuser, it belongs to the group of the so-called "catadioptric" optics. One advantage of this combination of lens and mirror: despite the large focal length, the telescope tube is relatively short and therefore easily transportable. In addition, you can look forward to a comfortable observation position at all times. This is because with telescopes of this design you do not look in at the back of the telescope, but at the front and laterally. So you don't have to bend down, even if the reflector telescope is pointed vertically upwards at the sky. The large aperture of 150 mm collects a lot of light from the celestial objects. In addition, 150 mm aperture and 1,400 mm focal length result in a focal ratio (ratio of aperture to focal length) of 1 to 9.3 (F/9.3). This allows you to enjoy viewing your favourite objects at high magnifications with good contrast. Admire especially the planets or details on the Moon through the entry-level telescope. But also some deep sky objects are very nice to observe: open star clusters, globular clusters and bright planetary nebulae such as the Ring Nebula M57 in the constellation Lyra can be seen beautifully through this astronomical telescope. But how close can you get to the celestial eye-catchers? The 150 mm aperture achieves a resolving power that allows magnifications of up to 300x with sharp images. The technical possibilities go far beyond this – theoretically up to 1,050x using the included accessories. However, as the magnification increases, the sharpness of the image can slowly decrease. In addition, high magnification also requires the right environmental conditions. For no matter through which telescope you look, the air turbulence in the atmosphere (seeing conditions) always influences your observation and magnification possibilities. Note for nature lovers: If you choose a Newtonian telescope like the Pollux-II 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. Solid base for gazing skywards – mount and tripod Have you found the perfect location for your journey of discovery into the night sky? Then simply mount your astronomical telescope with the equatorial mount on the height-adjustable aluminium tripod. The special feature of this type of mount: after the so-called "alignment", the positioning of an axis parallel to the Earth's axis, the movement of the celestial bodies only has to be compensated for on this one axis. To do this, you simply point the axis approximately at Polaris. This is a huge advantage over the azimuthal mount, where both axes are moved simultaneously. In addition, the two flexible shafts with fine adjustment make adjusting and tracking the telescope very precise and comfortable. And to ensure that accessories are always at hand, they can be stored on the handy shelf 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! Everything you need, night and day – the accessories The astronomical telescope comes with a wide range of equipment so that you can start admiring the Moon, planets or the Sun straight away. At night, the LED viewfinder helps you keep an overview of the sky. Once installed parallel on the tube and correctly aligned, the small red dot shows you where the telescope is pointing when you look through it. This way, you can align the optics precisely and find celestial bodies more quickly before you then take a closer look with the high magnification. Varying views of the universe: the two eyepieces allow you to marvel at your observation objects in different magnifications. They are simply inserted into the telescope's focuser using their sockets with a standardised 1.25 inch (31.7 mm) diameter. You want to see even more details? Then go for the 3x barlow lens, which triples the magnification of the eyepieces. If you would like to make astronomical discoveries even during the day, use the solar filter to observe the star of our own solar system. It allows you to easily and safely observe sunspots and granulation on the sun. CAUTION: Never point the telescope at the sun without the solar filter! Capture special highlights easily – with the smartphone adapter, you use your smartphone as a camera for your telescope. This way you can quickly take your first photos of the Moon or the Sun, for example, and get started in astrophotography. FEATURES Reflector telescope with 150 mm aperture and 1,400 mm focal length Reflector type catadioptric Well suited for observing the Sun, Moon and planets Height-adjustable tripod with equatorial EQ3 mount Precise adjustment through flexible shafts and fine adjustment in both axes Easy to use, very suitable for beginners Focal ratio F/9.3, therefore good for observing the planets and details on the moon 1.25 inch (31.7 mm) eyepiece focuser Two eyepieces and one barlow lens with 1.25 inch (31.7 mm) extension tubes for different magnifications Safe solar observation with the included solar filter Entry into astrophotography with smartphone camera adapter SCOPE OF DELIVERY Telescope Aluminium tripod Equatorial EQ3 mount 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 download Instruction manual

BRESSER Messier 6'' Planetary Dobson Telescope
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 6 inch Planetary Dobson is something very special. Despite its low price, it offers a variety of functions and quality, which you sometimes look for in the considerably more expensive devices in vain. With an aperture diameter of 150 mm and a focal length of 1200 mm of this high quality BRESSER newtonian optics, the observation of the moon, the planets and planetary nebulae is particularly well possible.  Craters and grooves of the moon as well as the fast changing shadows cast by the so-called terminator line are exciting observation targets. Saturn with its impressive ring, Jupiter with its bands of clouds and the movement of its easily visible moons, the crescent shape of Venus and the glowing red Mars are good examples of what this telescope can be used for. Because of the long basic focal length you can easily achieve the high magnifications required for this purpose with this telescope. You do not need expensive special eyepieces. In short, this is a telescope primarily for detailed observation. Nevertheless bright deep sky objects like the Orion Nebula or the galaxies Messier 81 and 82 etc. can be observed as well. Also photography is no problem with this tube. Here is another strength of this telescope: if you want to take pictures, you can simply unscrew the altitude wheels from the tube and put them on a EQ mount with an optionally available dovetail rail - and nothing more stands in the way of astrophotography. The included eyepiece adapter has the common T2 connection thread (M42x0.75mm), to which almost every standard camera can be attached. Only the camera specific T2 adapter ring is additionally required. Of course, also common USB planetary cameras with 1.25 inch or 2 inch plug diameter can be used directly with this telescope. With the original equipment you can observe immediately - an optical 6x30 viewfinder and a 25 mm SPL eyepiece are included. For those who want to transport the device as compact as possible, the new 6'' BRESSER Messier Planet Dobson makes it very easy - the rocker box can be disassembled in a few easy steps, because the parts are assembled with metal quick connectors. So a bulky rocker box quickly turns into a handy flat package of boards. A telescope whose versatility, performance and user-friendliness set new standards in this price class. Please note that Newtonian reflector telescopes are very good for astronomical observations of the starry sky, but are not well suited for observing nature and landscapes during the day. For nature and landscape observations we therefore recommend BRESSER lens telescopes.

EXPLORE SCIENTIFIC U-Mount with tripod for giant binoculars
Massive fork mount with excellent and adjustable mechanics for large binoculars with tripodWhen using giant binoculars, a stable mount and tripod with an appropriate load capacity is absolutely necessary. The new EXPLORE SCIENTIFIC U-mount with field tripod has been specially designed for the EXPLORE SCIENTIFIC BT series of giant binoculars, but also fits most other binoculars from 70 to 120mm lens diameter, which have a 1/4 inch photo thread connection on the underside. With the U-mount there is no shaking or annoying vibrations, the combination is as solid as a piece of iron and provides unlimited observation pleasure in all binocular adjustment positions. Whether you are observing the starry sky or the landscape, the U-mount is a solid base for your giant binocular and allows soft and smooth movements in both axes.The U-mount as a base for giant binoculars and always with you on every excursionAn easily transportable but solid mount is essential when using giant binoculars. A simple photo tripod with ball head or video tilt head is quickly overloaded here. The new EXPLORE SCIENTIFIC U-mount has an excellent mechanism with adjustable friction in both axes, and allows easy adjustment and tracking even when the load is fully utilised. Depending on the adjusted intensity of the friction, the binocular position is kept stable or a soft and smooth movement can be achieved. The large adjustment screws on both axes are smooth and easy to operate even with gloves and clammy fingers. Vibrations are reduced to an absolute minimum by the solid construction of the U-mount. Even at high magnification, there are no shakes and the finest details can be observed. The U-mount and tripod can be separated for easy transport.Mounting the large binoculars on the U-mountThe binoculars can be mounted and removed in a few seconds using the quick-release adapter plate included in the scope of delivery. This is a major advantage, especially for mobile outdoor use. The connection between binoculars and adapter plate is made by two 1/4 inch threaded bolts (standard photo tripod thread), which are variably guided in a slotted hole. A universal use with different binoculars is thus possible. The double screw connection guarantees a very secure fit of the binoculars. The adapter plate itself is also attached to the U-mount with the help of two large clamping screws, which are easy to use even when wearing gloves. Nothing wobbles here and all controls are easy to use.The field tripod provides a secure standNo matter what the surface, the EXPLORE SCIENTIFIC field tripod provides a safe stand. The solid aluminium and stainless steel construction effectively suppresses any kind of vibration. The large 50mm diameter stainless steel tripod legs and the aluminium tripod head plate are an ideal combination and offer maximum stability with a moderate transport weight of only 5.8kg. With applied and retracted tripod legs, the transport dimension is only 80cm long. The included accessory tray additionally gives some tension outwards to the tripod legs and thus to increase the stability. By pulling out the tripod legs, the working height for the binoculars can be individually adjusted within a range of approx. 100 to 140cm.
