SXP2WL SD115SII Complete Telescope Set with Wifi GoTo Mount, Tripod, and EyepiecesThis high-quality apochromatic refractor telescope-set impresses with its 115-mm-SD optics. The telescope is made in Japan and stands out with its excellent craftsmanship, sharpness, and contrast performance. The advantage of this SD refractor lies in its lightweight design and ability to produce color-pure and contrast-rich images. You'll be amazed when you observe the moon’s surface with its craters or Saturn with its ring system. On Jupiter, during a good night, you’ll even see the two bright cloud bands and many smaller details, such 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 more fascinating objects. Fainter celestial objects become visible thanks to this 115 mm wide aperture under a good sky.This telescope set "Made in Japan" leaves nothing to be desired. The FPL53 glass used in the telescope reproduces an extremely clear and sharp image by nearly eliminating any residual color errors. The SD glass is designed to bring all rays – violet, red, blue, yellow, and green – to the same plane. This special lens material reduces chromatic aberration across all colors. The new Vixen SD115SII has no spacers, which significantly improves image quality, especially for bright stars. In photographic images, no spikes are visible on the stars, which were previously caused by spacers.In combination with the optional SD Reducer HD Kit or SD Flattener HD (not included), this refractor telescope provides an image circle of 44 mm for full-frame DSLR cameras. The older ED81SII, ED103S, and ED115S refractors were originally developed for visual observers and photographers using APS-C cameras. However, the new SD series, with the use of new internal baffles, has been optimized for full-frame cameras. The large 60-mm focuser also allows for the attachment of heavy cameras without tilting. Additionally, the included flip mirror enables comfortable observation even in awkward situations and offers a T2 thread for attaching a DSLR camera. You can observe straight through or at a 90° angle. The carrying handle attached to the tube rings ensures a secure grip when transporting the telescope. The sturdy metal tripod ensures vibration-free mounting of the telescope and mount even in windy conditions. The SXP2WL mount is easily operated via a WiFi module with a smartphone or tablet. The free STAR BOOK Wireless app provides user-friendly mount control. With this app, you can use convenient celestial navigation functions such as automatic GoTo slewing to specific celestial objects easily through your smartphone or tablet. Since the conventional LCD screen (STAR BOOK TEN) is no longer required, the power consumption of the mount is reduced by up to 20%. This allows for longer periods of astronomical observation and astrophotography.Select the desired celestial object from a list, and it will be automatically slewed into the telescope’s field of view, and tracking begins. An existing STAR BOOK TEN controller can also be used with this mount without any issues. Equipped with the same precision stepper motors as the top model, the AXD mount, the SXP2WL sets a new standard of performance and precision in the Vixen mount family.The cross-axis of the SXP2 mount has a photographic payload capacity of 17 kg and weighs only 13.3 kg, making it ideal for mobile observations. Additionally, the motors in the lower part of the mount also act as counterweights, reducing the need for additional weights. The SXP2 mount features larger ball bearings than previous models to enhance accuracy and load capacity. The mount housing is also characterized by greater material thickness. To make the polar block even more stable, the cross-axis is securely clamped into a fork mount. The SXP2 Mount in Detail Stronger Mount BodyThe SXP2 mount is equipped with larger bearings than previous models to increase accuracy and load capacity. Additionally, the mount body is characterized by a thicker material. To further stabilize the polar block, the cross-axis is securely clamped into a fork mount. Very Precise Tracking with P-PEC FunctionThe SXP2 mount comes with the modern STAR BOOK TEN controller. It offers the P-PEC function for particularly precise tracking. "PEC" stands for "Periodic Error Correction". The system corrects mechanical errors caused by periodic gear errors. The P-PEC function available for the SXP2 equatorial mount is an enhancement of the PEC function. The P-PEC function stores your correction data even after the mount has been powered off. This means you do not need to re-enter the data every time, allowing for faster operation and more precise tracking. Low-Noise Belt Drive System with Minimal BacklashIn conventional motor drive systems for equatorial mounts, gears are driven by the motor. However, this design has the disadvantage of creating some backlash between the gears. To avoid the resulting inaccuracies, the SXP2 mount features a belt drive system. This significantly reduces both gear backlash and drive noise. In addition, the mount responds faster when corrections are needed. 16 BearingsThe mechanical parts of the SXP2 mount contain a total of 16 bearings. The RA axis is equipped with a set of tapered roller bearings to provide more stability for precise tracking. Stable Altitude Adjustment Block for AlignmentThe SXP2 mount uses the same fork as the heavier AXJ mount. This new design allows for quick and stable altitude adjustments. Easy and Precise Polar Alignment Using Reference StarsThe 6x20 polar finder is pre-installed. This allows for polar alignment in both the Northern and Southern Hemispheres. The polar finder features a variable illuminated reticle with an automatic shut-off function. The brightness can be adjusted in 8 levels to suit your individual needs. Additionally, the polar finder is equipped with a direct alignment system using three reference stars and can achieve accuracy up to 3 arc minutes. Variable Mounting HeadThe mounting head has a diameter of 35 mm and eight threaded holes for M8 screws, arranged 45 degrees apart. An optional accessory plate can be attached directly or in combination with an optional mounting block for dovetail plates. The threaded holes in the mounting head also allow the use of rails from other manufacturers. Combination of Innovative, Elegant Design and User-Friendly Operation The stable, rigid mount body with very precise tracking has been further optimized by the P-PEC function. This makes the SXP2 a highly precise and easy-to-use mount, sure to delight any astrophotographer or observer. Special Motor Positioning for Fewer CounterweightsThe heavy RA and DEC motor units are located in the lower part of the declination axis, placing the center of gravity of the cross-axis below the RA and DEC axis. This allows the declination body to act as a counterweight. The flat mounting head also enables the mount to be balanced with significantly fewer counterweights. Retractable Counterweight BarThe counterweight bar is made of solid stainless steel and has a diameter of 20 mm. It is compatible with all counterweights from the SX and GP mount series. The counterweight bar is housed in the declination body. Accessory Shoe The #35511 Polar Meter can be easily and quickly attached to this shoe for polar alignment. Latitude Adjustment The latitude can be adjusted between 0 and 70 degrees (divided into 3 zones and adjustable +/- 15 degrees per zone, for high, mid, and low latitudes).The Vixen Wifi Adapter in Detail The Vixen Wifi Adapter for EQ mounts allows you to control your Vixen mount via a smartphone or tablet. This enables you to use the STAR BOOK Wireless smartphone app (free) for celestial navigation without cabling. The app quickly turns your mobile device into a controller for the equatorial mount. The mount’s response delay, often considered the biggest drawback of wireless connections, has been reduced to a level comparable to wired solutions. Reduced Power Consumption Compared to Traditional Controllers with LCD Monitor The power consumption of the mount is reduced by up to 20%, enabling longer observation sessions compared to traditional wired controllers like the STAR BOOK TEN. Operation Similar to the STAR BOOK TEN Controller The STAR BOOK Wireless App is similarly structured to the STAR BOOK TEN controller. Depending on the star chart settings, it contains up to 259,000 celestial objects. Simply tap on an object in the list and start the GoTo. The mount will automatically move to the target and bring it into the telescope’s field of view. All the popular features of the STAR BOOK TEN remain available. Comfortable Operation While looking through the telescope, you can operate the mount by swiping on the app’s star chart. Since there are no buttons, you simply glide your finger over the star chart to easily control the mount. Extensive Astronomical Data Included This includes data on well-observed celestial bodies such as Messier objects, NGC objects, IC objects, as well as the sun, moon, planets, comets, and dwarf planets. High-Precision Alignment By aligning with one or two stars, you can achieve fairly accurate mount positioning. By aligning with three or more stars, a highly precise alignment for high magnifications can be achieved. Objects are then targeted precisely and centered in your telescope’s field of view. Alignment data is saved and can be retained even when the device is powered 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. Customizable Settings Like the STAR BOOK TEN controller, the app offers various individual settings such as gear backlash compensation, red night mode, autoguider, variable GoTo speed, and LED brightness. You can also set the timing of the optical tube flip (meridian flip) as desired. Even if the object moves south during tracking, you can prevent the telescope tube from flipping. Important Information Not compatible with older SX mounts using the old blue Star Book. Technical Information on the Wifi Module 32-bit CISC processor CPU 120 MHz The unit is connected to the mount via a D-SUB 9PIN connector, as with the STAR BOOK TEN.

The Vixen SD103SII Telescope OTA is a new 103 mm apochromatic refractor with high-performance Super-ED glass (= SD). The advantage of this SD refractor is its short length and low weight. The FPL53 glass reproduces an extremely clear and sharp image by an exceptionally high degree of elimination of residual chromatic aberrations. The SD glass is designed to bring all beams of violet, red, blue, yellow and green very precisely together on the same plane. The special lens material reduces chromatic aberration across all colours.The new Vixen SD103SII no longer uses spacer plates, which leads to a significantly better image quality, especially with bright stars. In photographic images, no spikes can be seen on the stars, which were otherwise produced by the spacer plates. In addition, you will be thrilled when you look at the moon or the brighter planets and observe the moon craters pin sharp as well as with extremely high contrast. Also look at the ring planet Saturn or the cloud bands on Jupiter. But of course, brighter deep sky objects such as the Orion Nebula or the Andromeda Galaxy can also be observed in impressive detail.In combination with the new optional SD Reducer HD Kit or SD Flattener HD, these refractors allow illumination with a 44 mm image circle for full format SLR cameras. The older ED81SII, ED103S, ED115S refractors were originally developed for visual observers and photographers using APS-C cameras. However, the new SD series is also optimised for use with full-frame cameras through the use of new inner baffle rings. The large 60 mm eyepiece extension also allows heavy cameras to be attached without tilting. Furthermore, the included folding mirror allows comfortable observation even in unfavourable observation situations and additionally offers a T2 thread for connecting a DSLR camera. This allows you to observe in straight line or at a 90° angle.

On moonless nights, you can also observe the Andromeda Nebula or the Orion Nebula. The sturdy metal focuser provides a secure and stable mount for eyepieces, camera or other accessories. The 6x24 finder allows you to find celestial objects very quickly and easily. You can also connect your DSLR camera to the telescope using the T2 thread built into the focuser with an optional T-adapter. The sturdy metal tripod enables vibration-free installation of the telescope and mount, even in windy weather. The ultra-modern SX2WL mount is simply operated via a Wi-Fi module with your smartphone or tablet.By simply controlling the mount with your smartphone or tablet and using the free STAR BOOK Wireless app, you can easily use sky navigation functions such as automatic GoTo panning for many celestial objects. By eliminating the conventional LCD display (STAR BOOK TEN), the power consumption on the mount is reduced by up to 20%, thus enabling longer astronomical observation and astrophotography.When you touch the desired celestial object on the star chart, it is automatically pointed into the telescope's field of view and tracking begins.NOTE: An existing STAR BOOK TEN or ONE 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 SX2WL 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 is just 7 kg light, making it ideal for mobile observations. In addition, the motors mounted in the lower part of the mount also serve as a counterweight and the mount therefore requires fewer weights for balancing.The SX2WL mount in detailPrecision stepper motors and micro-step motion control systemAt the heart of the SX2 are the precision stepper motors, which offer better performance and response than previous models. The micro-step motion control system scores with powerful yet very smooth drive characteristics, which are present in both fine movements and fast pans.Built-in bearingsThe 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 running surfaces of the two worms and worm wheels are manufactured to be particularly smooth, enabling very precise tracking.Declination axis as counterweightThe massive motor units are installed in the lower part of the declination axis so that the center of gravity of the SX2WL is below the intersection point of the RA and DEC axes. This means you need fewer additional counterweights.Latitude adjustmentThe latitude is adjustable between 0 and 70 degrees (divided into 3 zones and adjustable in +/- 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 detailThe 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 "STAR BOOK Wireless" smartphone app transforms 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 monitorThe power consumption of the mount is reduced by up to 20%, allowing longer observations than with conventionalwired controllers such as the STAR BOOK TEN.Operation similar to the STAR BOOK TEN control unitThe STAR BOOK Wireless app has a similar structure to the STAR BOOK TEN control system. Depending on the star map setting, it contains up to 259,000 celestial objects.

Ultra Light Dobsonian 406mm 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 406mm aperture gathers more than 3300-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.
