BRESSER Messier 6" Dobson

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.

The BRESSER Messier 5" dobsonian is simply a breakthrough. Despite of its low price this telescope offers a versatility and quality rivaling a lot more expensive telescopes. Not only for beginners - also enthusiastic and experienced amateur astronomers love this high performance and compact telescope for traveling and to discover the night sky. The main goal of this telescope is the quick setup and the ease of use. Simply put the Messier 5" Dobson telescope on a table in your backyard, point the telescope to your target object and you are ready to start your observation. The Messier 5" Dobson is almost pre-assembled ex factory which means you can start within minutes. With the included standard accessories (LED-finder, 25mm and 9mm Kellner eyepieces and Moonfilter) the telescope is ready for observing. The inbuild compass and circular level speeds up the telescopes orientation. The optical diameter of 130mm (5") 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. Finding and observing is much easier with that light gathering richfield telescope. Bresser also has equipped these dobsonians with a high quality main mirror which offers a very good sharpness and contrast. In addition, this telescope has a particularly large secondary mirror for ideal illumination of the image field.The optical tube can easily be moved inside the tube rings in order to find the optimal balance and observing position. This is another virtue of this highly versatile telescope system: Remove the optical tube from the dobsonian telescope mount and use the optics on a equatorial mount for astrophotography with smartphones und eyepiece cameras - in minutes. Bresser has not skimped and this telescope has a particularly large secondary mirror for ideal illumination of the field of view. The entire telescope tube can be moved and rotated in the tube clamps - everything is thus balanced in a flash and a comfortable position for viewing is set. A permanently installed compass with circular bubble facilitates the orientation of the telescope. 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.

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.

NEW - now including a high-quality lens solar filter for the safe observation of sunspots, eclipses and planetary transits. A high quality telescope for night and solar observation.The BRESSER Messier 10 "Dobsonian is something very special. Despite the low price, it offers a variety of functions and quality that are sometimes unavailable in considerably more expensive telescopes. With its 254 mm diameter optics, this telescope is not limited to solar system observation of the Moon and brighter planets - you can also observe far out into the universe and see globular clusters, nebulae and galaxies. Details become visible in most deep-sky objects: globular clusters are broken down into individual stars and nebulae, which are only hinted at in smaller scopes, show considerable structure. This Dobsonian is unsurpassed in versatility within its price range: the excellent, large Hexafoc focuser has an opening of 65 mm - so even with large wide-field eyepieces, there is no noticeable vignetting from the eyepiece extension tube. The large elevation wheels also hold the telescope level with just the right amount of "sticktion", even when heavier eyepieces are used. And when a lot of heavier accessories are attached, such as the Bresser Binoviewer attachment, then the entire telescope tube can be moved within the tube rings - and everything is balanced again in a flash. The unsurpassed rigidity of the focuser makes it easy to focus - photography with this OTA is no problem either as the supplied extension tube for the focuser can be removed and a camera easily bought to a prime focus position. This is another strength of this universal telescope: if you want to take photos, you can simply unscrew the elevation wheels from the tube and place it on an equatorial mount with a standard dovetail rail - other rival Dobsonians do not offer this level of flexibility or pathway to more expansive astrophotography use. An optional dual speed 10:1 gear reduction for the focuser is available for those who need extra fine control of focus. If you consider that the focuser is the telescope part that is used most often, the supply of the Hexafoc on this telescope is a quantum leap for this price range.With the initial equipment you can observe immediately - a 6x30 viewfinder and a 25mm SPL eyepiece are included within the package.  If you want to transport the device as compactly as possible, it is easy with the new 10 "BRESSER Messier - the rocker box can be dismantled in a few simple steps, as the parts are assembled with metal quick-release connectors. A bulky rocker box quickly becomes a handy flat package of boards within a few minutes. This is a telescope whose versatility, performance and ease of use set new standards in this price range.Please note that while Newtonian type reflecting telescopes are very good for astronomical observations in the night sky, they not well-suited for observing nature and landscapes during the day.

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

Who doesn't dream of exploring the beauties of the universe with their own eyes? This complete telescope set allows you to make your first celestial observations immediately and very easily. It contains everything you need for your new hobby: a reflector telescope with 130 mm aperture and 650 mm focal length, an equatorial mount, a tripod and extensive accessories for astronomical observations. The system is easy to operate and very flexible. You can look forward to fascinating views of the Moon and planets. Star clusters and gas nebulae also look impressive through the user-friendly entry-level telescope. Easy start with the astronomy all-rounder – the telescope The set includes a true classic among the reflector telescopes, a so-called Newtonian reflector. With this type of telescope, you look in at the front of the tube instead of at the back. The advantage: the observing position always remains comfortable, even when the telescope is pointed vertically upwards. In addition to observing comfort, reflectors also impress with their optical performance. After all, they are absolutely free of chromatic aberrations and thus offer good imaging properties. Due to its 130 mm aperture, the entry-level telescope already collects a lot of light from the celestial objects. In addition, there is the short focal ratio (ratio of the aperture to the focal length) of 1 to 5 (F/5), which derives from the 130 mm aperture and the 650 mm focal length. As a result, the fast beginner's telescope shows a bright image and enables high magnifications. You also benefit from the flexibility of this astronomical telescope: Admire the fascinating view of open and globular clusters such as M13 in the constellation Hercules at low to medium magnification. Or marvel at gas nebulae such as the famous Orion Nebula M42. At high magnifications, on the other hand, the entry-level telescope brings you closer to the impressive planets and exciting details on our Moon. How big do the astronomical eye-catchers appear? Due to the resolving power achieved with the aperture of 130 mm, the telescope shows you sharp images at magnifications up to about 260x. With the included accessories, you can already reach 195x. The technology allows even more, but the image sharpness can decrease at even higher magnifications. However, it is not only the telescope that determines how much you can magnify. It also depends on the air turbulence in the atmosphere (seeing conditions). Note for nature lovers: If you choose a Newtonian telescope like the Pegasus 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. User-friendly base – mount and tripod Found the perfect place for your celestial observations? Then you can start installing your astronomical telescope on the height-adjustable stainless steel tripod with equatorial mount. The advantage over azimuthal mounts: you only have to move along one axis instead of two. The reason is that you align the other one parallel to the earth's axis beforehand. This so-called "alignment" is very easy: you simply point the axis approximately at Polaris. In addition, the mount comes equipped with two flexible shafts with fine adjustment. Perfect for aligning and tracking the telescope particularly precisely and comfortably. Everything always within reach: on the practical storage plate, your accessories are quickly at hand if needed.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! Complete astro package to start stargazing immediately – the accessories The comprehensive astronomy accessories make it easier for you to get started and enable you to see your favourite celestial bodies from completely different perspectives. To align the telescope and find your way around the night sky you can mount the LED finder parallel to the telescope. The method is simple: a red dot is projected onto a small ground-glass screen inside the viewfinder. When you look through the dot appears to hover in front of the sky – exactly at the point where the entry-level telescope is pointed. This way, you can easily find astronomical objects through the illuminated dot finder and then marvel at them in detail using the high magnification of your telescope. Vary your view of the stars: with the two eyepieces (10 mm and 25 mm), you can admire your nocturnal observation objects in two different magnifications. They are simply inserted into the eyepiece focuser of the telescope via their 1.25-inch-sockets, which is a standard diameter. You want to look even closer? Then the included 3x barlow lens can triple the magnification of the eyepieces. Explore the night sky on your own through the versatile BRESSER Pegasus 130/650 EQ3 reflector telescope. FEATURES Reflector telescope for beginners with 130 mm aperture and 650 mm focal length Reflector type: Newton Good for observing Moon, planets as well as star clusters and gas nebulae Height-adjustable tripod with equatorial EQ3 mount Precise positioning due to flexible shafts and fine adjustment in both axes Easy to use, very well suited for beginners Focal ratio F/5, thus well suited for many celestial objects 1.25 inch (31.7 mm) focuser Two eyepieces and a barlow lens with 1.25 inch (31.7 mm) sockets for different magnifications SCOPE OF DELIVERY Telescope Stainless steel tripod Equatorial EQ3 mount Eyepieces: 10 mm and 25 mm (1.25 inch sockets) Barlow lens 3x (1.25 inch socket) LED illuminated dot finder Accessory tray Astronomy software download Instruction manual

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.
