Vixen SXD2WL Equatorial GoTo Mount with Wifi

Ultra Light Dobsonian 254mm GENERATION II - with completely redesigned and improved construction.No telescope type has influenced amateur astronomy as radically as the dobsonian telescope. Before the introduction of this telescope type by John Dobson the vast majority of amateur telescopes were small inadequate refractors on shaky mounts - just good enough to show the polar regions on mars or the rings of Saturn. Bigger telescopes, like the Schmidt-Cassegrain telescopes, were restricted to the relatively small group of amateurs that could afford them.The brilliant combination of simple - but effective - mechanics and the largest aperture available led to a worldwide triumph of this concept. No other telescope type offers you so much light for your money as a good dobson. We have taken the motto "held together by gravity and driven by yoghurt power" and offer a modern version of the classic - designed by amateur astronomers for amateur astronomers. Despite its large aperture the telescope can be transported easily even in small cars and is assembled within minutes without tools. The construction was optimized for maximum rigidity with a minimum of mass. The combination of big altitude wheels and a optimized aluminium-sandwich construction allows for small movements even at high magnifications. The focus position is already positioned to accept our coma-corrector. The ideal workhorse for the deep-sky enthusiast. A telescope with 254mm aperture gathers more than 1300-times more light than the naked eye. Details on planetary surfaces stand out even to unexperienced observers, and countless deep-sky objects show details. Bright globular clusters are resolved down to the core and the view of the lunar terminator will provide a unforgettable experience.Dimensions for mobile use: Rockerbox 395mmx395mmx310mm; Mirrorbox 330mmx330mmx295mm; Trusses approx.700mmEyepiece Height while pointing at zenith approximately 1,15m; 10“ Net total weight: 26,4 kg; 10“ Mirror Box: 14 kg; 10“ Secondary cage +Rockerbox: 9,7kg; 10“ 4 Pairs of trusses: 1,5kg; 10“ Altitude Wheels: 1,2kg ; Focuser thread: M54 x 0.75 mm. Backfocus: 45mm behind the 2" eyepiece holder. 35mm when the 1.25" adapter is mountedSPECIFICATIONS Truss-Dobsonian Telescope in full Aluminium constructionNEW: Slider bearings made from TEFLON und GFK for smooth and precise movementNEW: Improved main mirror cell with completely redesigned mechanicsNEW: Altitude bearings with new designed brake and friction systemNEW: Universal finder slot to enable an easy finder upgradeNEW: Quick-lock fasteners with new springloaded design for comfortable useNEW: Powder-coated yellow altitude wheels to improve durabilityNEW: Laser engraved central mark on main mirrorSCOPE OF DELIVERYTruss Dobsonian TelescopeLED finder with standard finder slotStray light shield for secondary cageMain mirror collimation toolBattery compartment with bag for fansExtension tube for focuserReducer 2"/1.25"Manual

The Twilight I is a light-to-medium-duty alt-azimuth mount with tripod designed to quickly and easily accept small to medium sized refractors, such as the AR102 + AR127s or ED102mm + ED127, and of course, the ED80mm. Lightweight, fast Newtonians will also match up nicely with the BRESSER Twilight I mount. As long as your telescope does not exceed 18 pounds and has a Vixen-Style Universal Dovetail bar for mounting the telescope to the mount head, you are good to go. The Twilight I alt-azimuth mount head is made of powder-coated aluminum and there are worm gears on both axes. The adjustable angle head can be tilted forward or back at a 45° angle to allow more clearance for your telescope so you can point it straight up for viewing at the zenith. The Allen hex wrench for doing the mount head adjustment can be safely stored at the integrated magnetic holder.  Slow-motion control cables are attached on the vertical and horizontal axes, and are easy to turn during the night, even with gloves on, due to the over-sized knurled knobs that are attached to the end of each cable. They can be attached to either side of each axis to accommodate right or left-handed users, or different types of telescopes (e.g. refractors vs. Newtonian reflectors) for ease of adjustment. The stainless steel tripod that comes standard with the Twilight I mount has adjustable legs and a wide foot print of 42 inches, which makes the tripod more stable. A spreader bar locks against the inside of the legs to secure the tripod even further, and keep vibrations to a minimum. SCOPE OF DELIVERYTwilight I Telescope MountStainless Steel Field tripod

The BRESSER Biolux NV comes with a wide range of accessories and is an ideal beginners' microscope. A unique feature of these models, the Barlow zoom system is inside the eyepiece tubes: With the barlow lens the magnification can be  varied by a factor of 2 in visual observation. This feature, together with 3 objectives and 2 interchangeable wide field eyepieces gives a magnification range from 20x to 1280x. With the mechanical desk you can move your sample precisely even when observing at high magnifications. For optimal illumination a variable LED for transmitted and incident light together with a filter wheel gives the ideal light for all samples. Light from above is especially imortant to observe non transparent samples like leaves, small insects and much more. This makes microscopy for beginners very easy! The power is supplied by batteries (3x AA). A dust cover, 5 prepared slides and 5 blank slides and cover slips are included for making your own samples. With the included HD camera you can observe your samples on the computer screen, and capture images and video with the included Windows software.

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.

Vixen has developed a new generation of SX mounts for demanding observers and astrophotographers. The SX2WL mount is simply operated via a Wifi module with a smartphone or tablet. By controlling the mount with your smartphone using the free STAR BOOK Wireless app, you can easily use sky navigation functions such as automatic GoTo panning of celestial objects via your smartphone or tablet. By eliminating the power consumption of the conventional LCD (STAR BOOK TEN), the power consumption on the mount is reduced by up to 20%, thus enabling longer astronomical observation and astrophotography. When the desired celestial object is selected from a list, it is automatically panned into the telescope's field of view and tracking begins.An existing STAR BOOK TEN controller can also be used on this mount without any problems. Equipped with the same precision stepper motors as the top model, the AXD mount, the SXD2WL brings a new standard of performance and precision to the Vixen mount family. With a photographic load capacity of 12 kg, the axis cross of the mount weighs just 7.0 kg (15.4 lbs) making it ideal for mobile observations.In addition, the motors mounted in the lower part of the mount also serve as a counterweight, so the mount requires fewer weights for balancing. The SX2 mount in detail Precision stepper motors and micro-step motion control systemAt 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 offers powerful and yet very smooth drive characteristics, which are given both in fine movements and in fast pans. 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. As a result, the motors move much more smoothly than in previous models. High-precision worm gearsHigh-precision processing technologies eliminate worm gear errors. The edges of the two worms and worm wheels are particularly smooth, enabling very precise tracking. Declination axis as counterweightThe solid motor units are installed in the lower part of the declination axis so that the center of gravity of the SXD2 is below the intersection point of the RA and DEC axes. This means you need fewer additional counterweights. Latitude setting 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 increments; fine adjustment with a tangent screw head, approx. 0.8 degrees per turn. 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 of charge) you can navigate the sky without any cables. The app turns your smartphone or tablet into a control unit for the equatorial mount in no time at all. The response delay of the mount, which is considered the biggest disadvantage of wireless connections, has been reduced to a level comparable to wired connections. Reduced power consumption compared to conventional controllers with LCD monitor The power consumption of the mount is reduced by up to 20%, allowing longer observations than with conventional wired controllers such as the STAR BOOK TEN. Operation similar to the STAR BOOK TEN controllerThe STAR BOOK Wireless app has a similar structure to the STAR BOOK TEN controller. Depending on the star map setting, it contains up to 259,000 celestial objects. Tap on a celestial object in the object list and start the GoTo. The mount will now automatically move to this target and bring it into the telescope's field of view. All the popular features of the STAR BOOK TEN are retained. Convenient operation When looking through the telescope operate the mount by swiping on the app's star chart. As there are no buttons, simply slide your finger over the star chart to operate the mount conveniently. Extensive astronomical data included In addition to data on easily observable celestial bodies such as Messier objects, NGC objects and IC objects, this also includes the sun, moon, planets, comets and dwarf planets. High-precision alignment By aligning the mount to one or two stars, you can already achieve fairly precise positioning. By aligning the mount to three or more stars, you can achieve high-precision alignment of the mount for high magnifications. The objects are then approached precisely and centrally in your telescope's field of view. The alignment information is saved and can be retained even when the device is switched off. By leaving the telescope in its current state after completing an observation without moving it, you can start the automatic installation with the same settings for the next observation.  Individual setting options As with the STAR BOOK TEN control unit, the app offers various individual settings, such as gear backlash compensation, night mode in red, autoguider and variable GoTo speed and LED brightness. You can also set the timing of the reversal of the objective tube (meridian flip) as desired. Even if the object moves to the south during tracking, you can prevent the telescope tube from reversing. Important note: Cannot be used on old SX mounts with the old blue Star Book! Technical information about the Wifi module: CPU with 32-bit CISC processor 120 MHz The unit is connected to the mount via a D-SUB 9PIN connector as with the STAR BOOK TEN. It has a 6-pin 6-wire modular plug for external autoguider operation.
