BRESSER Pollux-II 150/1400 EQ3 Reflector Telescope with Smartphone Adapter & Solar Filter

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.

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 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.

Complete Telescope Set SXD2WL AX103S with Wifi-GoTo Mount, Tripod, and Eyepieces This high-quality apochromatic refractor telescope set impresses with its intricate 103mm Triplet ED lens construction. The telescope is made in Japan and stands out for its excellent workmanship, sharpness, and contrast performance. The advantage of this APO refractor lies in its short build length and the completely corrected, edge-sharp optics. The AX103S is a top-class ED apochromat in the refractor range. It offers a Triplet ED lens and, in the rear area, a field flattener lens. The f8.0 refractor is equipped with a central ED lens in the objective and reduces chromatic aberration to an absolute minimum. An optional focal reducer can decrease the aperture ratio to 1:5.6 to achieve quicker results in astrophotography. The Vixen telescope belongs to the new Generation II with improved temperature-resistant lens cell. The integrated field flattener lens ensures a sharp image right to the edge of the field of view, which is very important in astrophotography. The AX103S is specifically developed for photographic purposes, but also visually a real highlight, especially for observing the moon and planets. You will be thrilled when you observe the moon's surface with its craters or Saturn with its ring system. On Jupiter, on a good night, the two bright cloud bands and many smaller details will be visible, as well as the great red spot on the planet. On moonless nights, you can observe the Andromeda Nebula, Orion Nebula, Eagle Nebula, Lagoon Nebula, and many other interesting objects. But even weaker celestial objects become visible with this large aperture under a good sky. This telescope set “Made in Japan” simply leaves no wishes unfulfilled. The AX103S is corrected up to full-frame photography and delivers razor-sharp images right into the corners of the image field. The large 60mm eyepiece drawtube also allows for attaching heavy cameras without tilting. Furthermore, the supplied flip mirror enables comfortable observing even in challenging viewing situations and additionally offers a T2 thread for connecting a DSLR camera. Thus, you can observe in straight view or at a 90° angle. The carrying handle attached to the tube clamps ensures a safe transport of the telescope. The dew cap can be retracted for transport or storage. The sturdy metal tripod allows for vibration-free mounting of the telescope and mount even in windy weather. The SXD2WL mount is simply operated via a Wifi module with a smartphone or tablet. For user-friendly control of the mount, the free STAR BOOK Wireless app is available. This allows you to use practical features of celestial navigation such as automatic GoTo slewing to specific celestial objects very easily via your smartphone or tablet. As the power consumption of the conventional LCD screen (STAR BOOK TEN) is eliminated, the power consumption of the mount is reduced by up to 20%. Thus, astronomical observations and astrophotography are possible over longer periods. By tapping the desired celestial object from a list, it is automatically slewed into the telescope's field of view and tracking begins. An existing STAR BOOK TEN control can also be used on this mount without any problems. Equipped with the same precision stepper motors as the flagship model, the AXD mount, the SXD2WL brings a new standard of performance and precision into the Vixen mount family. The axis cross of the mount has a photographic carrying capacity of 15 kg for only 9.2 kg and is thus excellently suited for mobile observations. In addition, the motors located in the lower part of the mount also serve as a counterweight. This means the mount needs fewer weights for balancing. The SXD2 Mount in Detail Precision stepper motors and Micro-Step Motion Control System The heart of the SXD2 are the precision stepper motors, which offer better performance and response than previous models. The Micro-Step Motion Control System is characterised by powerful yet very quiet drive properties, both in fine movements and in fast slews. Built-in bearings The bearings of the RA and DEC axes and the worm shafts have been significantly improved to reduce the load on the motors. This allows the motors to move much more quietly than in previous models. High-precision worm gears High-precision manufacturing technologies eliminate errors in the worm gears. The edges of both worms and worm gears are particularly smooth, allowing for very precise tracking. Declination axis as counterweight The massive motor units are built into the lower part of the declination axis, so that the centre of gravity of the SXD2 is below the intersection point of the RA and DEC axes. This means you need fewer additional counterweights. Latitude adjustment The latitude is adjustable between 0 and 70 degrees (divided into 3 zones and adjustable +/- 15 degrees per zone, for high, medium, and low latitudes); latitude scale in 2-degree steps; fine adjustment with a tangent screw head, approx. 0.8 degrees per rotation. Built-in PFL-II polar finder with illumination The built-in 5x20mm polar finder with 10° field of view features a 3-star alignment system. This eliminates the need to set date and time. The illuminated reticle with variable brightness and automatic shutdown is adjustable in 8 stages and illuminated in red. The adjustment accuracy is 3 arc minutes. The Wireless Module in Detail The Vixen Wifi adapter for EQ mounts allows you to control your Vixen mount via a smartphone or tablet. With the smartphone app STAR BOOK Wireless (free), you can perform celestial navigation without any wiring. Thus, the app instantly transforms your mobile device into a control for the equatorial mount. The response delay of the mount, considered the biggest disadvantage of wireless connections, has been reduced to a level comparable to wired solutions. Reduced power consumption compared to conventional controls with LCD monitor The power consumption of the mount is reduced by up to 20% and thus allows longer observations than with conventional wired controls like the STAR BOOK TEN. Operation similar to STAR BOOK TEN control The STAR BOOK Wireless app is designed similarly to what you already know from the STAR BOOK TEN control. It contains up to 259,000 celestial objects depending on the star chart settings. Tap a celestial object in the object list and start the GoTo. The mount now automatically moves to this target and brings it into the field of view of the telescope. All popular features of the STAR BOOK TEN remain available. Convenient operation While looking through the telescope, you control the mount by swiping on the star chart of the app. Since there are no buttons, you simply slide your finger over the star chart, allowing you to conveniently operate the mount. Extensive astronomical data included This includes data on easily observable celestial bodies such as Messier objects, NGC objects, IC objects, as well as the sun, moon, planets, comets, and dwarf planets. High-precision alignment Alignment on one or two stars already gives you quite an accurate positioning of the mount. By aligning with three or more stars, a very precise alignment of the mount for high magnifications can be carried out. The objects are then positioned exactly and centrally in the field of view of your telescope. The alignment information is saved and can also be retained when the device is turned off. By leaving the telescope in its current state after an observation, without moving it, you can start the automatic installation with the same settings during the next observation. Individual Adjustment Options The app offers various individual settings such as gear backlash compensation, red night mode, autoguider, variable GoTo speed, and LED brightness, just like the STAR BOOK TEN control. You can also set the timing of the objective tube reversal (Meridian Flip) according to your wishes. Even if the object moves south during tracking, you can prevent the telescope tube from reversing. Important Information Not usable on old SX mounts with the old blue Star Book Technical Information on the Wifi Module CPU with 32-bit CISC processor 120 MHz The unit is connected to the mount with a D-SUB 9PIN connector as with the STAR BOOK TEN. It has a 6-pin 6-wire modular connector for external autoguider operation.

Take a closer look at the wonders of the universe. This complete telescope set for beginners contains everything you need for your new hobby: a refractor telescope with 80 mm aperture and 900 mm focal length, an equatorial mount, a tripod and a wide range of accessories for astronomical observations. The system is very easy to handle and can even be used by children. Simply unpack, set up and get started – you will be amazed at what you will discover! Easy start with user-friendly classic – the telescope The astronomical telescope is a traditional lens telescope, a so-called Fraunhofer achromatic refractor. The advantage of this established telescope type: even beginners and children find it easy to operate. In addition, the BRESSER Quasar scores points for its modern, precisely coated optics with good imaging properties. A direct comparison shows: With its 80 mm aperture, this telescope already collects 30 % more light than a 70 mm telescope and the resolving power is better as well. This means that you can already marvel at some of the details on Mars through the Quasar. In addition, 80 mm aperture and 900 mm focal length mean a large focal ratio (ratio of the aperture to the focal length) of about 1 to 11.3 (F/11.3). The result: a very sharp image with good contrast. Due to its long focal length the entry-level telescope is a specialist when it comes to observing the moon, sun, planets, open star clusters and globular clusters. But you can also take a look at many gas nebulae through this telescope, such as the famous Orion Nebula M42 or the Ring Nebula M57. How big will you see the fascinating celestial bodies? The 80 mm aperture achieves a resolving power that easily allows magnifications of up to about 160x with really sharp images. Technically, much more is possible, theoretically up to 675x using the included accessories. However, with increasing magnification, the sharpness of the image can slowly decrease. In addition to the equipment, the conditions play a role as well: the air turbulence in the atmosphere (seeing conditions) also determines how much you are able to magnify. Sturdy base for your easy astro-beginning – mount and tripod Found the perfect spot for your nocturnal explorations? Then install the telescope effortlessly on the height-adjustable aluminium tripod using the equatorial mount. The advantage of this type of mount: unlike the azimuthal models, you compensate for the movement of the celestial bodies along just one axis instead of two. To do this, you align one axis parallel to the Earth's axis, which is called "alignment". This is easily done by pointing it approximately to Polaris. The beginner's telescope also comes with two flexible shafts with a fine adjustment, which simplify the movement of the axes. They make adjusting and tracking very precise and comfortable. Handy storage: On a plate between the tripod legs, you can store your accessories within easy reach.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! The complete package for your sky observations – the accessories The extensive astronomy accessories including a safe solar filter enable you to immediately direct your gaze through the lens telescope to the sky – day and night. When observing at night, the LED viewfinder helps you find your way around: just install it parallel on the telescope, adjust it and use it to align and locate celestial objects. When you look through it, the red dot projected onto a ground-glass screen inside appears to hover in front of the sky. It shows you the spot to which the tube is pointing. This allows you to navigate easily before taking a closer look with the telescope's high magnification. Different perspectives of your astronomical discoveries are made possible by the two eyepieces, which enable different magnifications. With their sockets, which have a standard diameter of 1.25 inch (31.7 mm), they are simply inserted into the telescope's focuser. You want to see even more details? Then triple the magnification of the eyepieces with the 3x barlow lens. Always comfortable while observing the stars – for this purpose the 90-degree star diagonal mirror is included. That way you always enjoy a pleasant view into the telescope. Even if it is pointed upwards into the sky, you can comfortably look in from the side. Discover the beauty of our own star: Using the telescope in combination with the solar filter you can safely observe sunspots and granulation on the sun. CAUTION: Never point the telescope at the sun without the solar filter! Have you always been fascinated by astrophotography? Then your smartphone camera and the smartphone adapter will get you started. This way you'll quickly enjoy your first own photos e. g. of the moon or the sun. FEATURES Beginner’s lens telescope with 80 mm aperture and 900 mm focal length Fraunhofer achromatic refractor Ideal for observing the sun, moon, planets and star clusters 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 and children Focal ratio F/11.3, thus very sharp image and high contrast 1.25 inch (31.7 mm) focuser Two eyepieces and a 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 Beginner’s telescope Aluminium tripod Equatorial EQ3 mount Eyepieces: 4 mm und 20 mm (1.25 inch sockets) Barlow lens 3x (1.25 inch socket) Star diagonal mirror LED illuminated dot finder Solar filter Smartphone camera adapter Accessory tray Astronomy software download Instruction manual

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.In the past few years the Bresser Newton telescopes have become the standard workhorse for Deep Sky astrophotography. We now proudly present the second generation of this telescope, the Bresser NT-203s/800 with Hexafoc and fast parabolic main mirror. The Bresser NT-203s/800 f3.9 will deliver you deeper images due to its - compared to 8" f/5 systems - oversized primary mirror and therefore faster optical system with the same exposure time. The big 85 mm secondary prevents vignetting for optimal illumination The excellent 2,5" Hexafoc focuser also does not cause vignetting due to its large diameter and makes focussing a joy - the smoothness and shifting-free operation sets new standards in this price class. This groundbreaking focuser, tube rings with 44mm universal standard dovetail and camera mounting feature and a high-end finderscope with haircross and laser-engraved scale  leave nothing to desire even for demanding astrophotographers. The NT-203s/800 Hexafoc has a classical tube construction with an aluminium tube. The focuser can be upgraded with a 10:1 reduction (part No. 0625720) without problems. Also prepared for use with the HR Coma Corrector (part No. 0510330) which eliminates coma, field-curvature and astigmatism.Mount and Tripod. The BRESSER EXOS 2 is a rugged mount with high rigidity and precision tracking for visual observation and astrophotography. The tripod is extremely rigid to suppress vibrations really well. This model is very well machined and has an illuminated polar finder scope and precise graduated circles. A powered twoaxis control (BRESSER Exos Duo) or a GoTo-Kit is available as an optional extra. The BRESSER EXOS 2 can take the weight - depending on length and use of up to 13 kg. This allows you to use refractors of up to 152 mm aperture and mirror telescopes of up to 203 mm aperture.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.
