{"product_id":"vixen-sx2wl-sd103ii-refractor-telescope","title":"Vixen SX2WL SD103SII Refractor Telescope","description":"\u003cp\u003e\u003cstrong\u003eThis high-quality apochromatic refractor telescope is manufactured in Japan and impresses with its excellent workmanship, sharpness and contrast performance. The advantage of this SD refractor is its short length and low weight. You will be amazed when you use it to observe the surface of the moon with its craters or Saturn with its complex ring system. \u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eOn a good night, the two bright cloud bands on Jupiter and many other details, such as the large red spot on the planet, will also be visible. On moonless nights you can even observe the many galaxies, nebula and other deepspace objects under very dark skies\u003c\/p\u003e\n\u003cp\u003eThe FPL53 glass used in the telescope reproduces an extremely clear and sharp image thanks to an extraordinarily high elimination of residual chromatic aberration. The SD glass is designed in such a way that it brings all rays - violet, red, blue, yellow and green - very precisely together on the same plane. The special lens material therefore reduces chromatic aberration across all colours.\u003c\/p\u003e\n\u003cp\u003eThe new Vixen SD103SII no longer uses spacer discs, which leads to significantly better image quality, especially with bright stars. Photographic images do not show any spikes on the stars that would otherwise be caused by the spacer discs. In combination with the optional SD Reducer HD Kit or SD Flattener HD (not included), this refractor telescope enables illumination with a 44mm image circle for full-frame SLR cameras. The older ED81SII, ED103S, ED115S refractors were originally developed for visual observers and photographers with APS-C cameras. However, the new SD series is also optimised for use with full-frame cameras thanks to the use of new internal diaphragms. The large 60mm focuser also allows heavy cameras to be attached without tilting. Furthermore, the supplied folding mirror allows comfortable observation even in difficult observation positions and also offers a T2 thread for connecting a DSLR camera. The carrying handle attached to the tube clamps ensures a secure grip when transporting the telescope. The sturdy metal tripod enables the telescope and mount to be mounted without vibration, even in windy weather.\u003c\/p\u003e\n\u003cp\u003eThe 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.\u003c\/p\u003e\n\u003cp\u003eNOTE: An existing STAR BOOK TEN or ONE controller can also be used on this mount without any problems.\u003c\/p\u003e\n\u003cp\u003eEquipped 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.\u003cbr\u003eWith a photographic load capacity of 12kg, the axis cross of the mount is just 7kg 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.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDetails of the SX2 Mount:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003ePrecision stepper motors and micro-step motion control system\u003cbr\u003eAt 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.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eBuilt-in bearings.\u003c\/strong\u003e\u003cbr\u003eThe 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.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHigh-precision worm gears.\u003c\/strong\u003e\u003cbr\u003eHigh-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.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDeclination axis as counterweight.\u003c\/strong\u003e\u003cbr\u003eThe 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.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eLatitude adjustment.\u003c\/strong\u003e\u003cbr\u003eThe 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.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eThe wireless module in detail.\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe 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.\u003c\/p\u003e\n\u003cp\u003eReduced power consumption compared to conventional controllers with LCD monitor\u003cbr\u003eThe 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.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eOperation similar to the STAR BOOK TEN control unit.\u003c\/strong\u003e\u003cbr\u003eThe 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. 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.\u003cbr\u003eAll the popular features of the STAR BOOK TEN are retained\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eConvenient operation.\u003c\/strong\u003e\u003cbr\u003eWhen 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.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eExtensive astronomical data included.\u003c\/strong\u003e\u003cbr\u003eIn 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.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHigh-precision alignment.\u003c\/strong\u003e\u003cbr\u003eBy aligning the mount to one or two stars, you can already achieve fairly precise positioning of the mount. By aligning 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 the field of view of your telescope. 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.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eIndividual setting options.\u003c\/strong\u003e\u003cbr\u003eAs with the STAR BOOK TEN controller, the app offers various individual settings, such as gear backlash compensation, night mode in red,\u003cbr\u003eautoguider, variable GoTo speed and LED brightness. You can also set the timing of the reversal of the objective tube (meridian flip) as required.\u003cbr\u003eEven if the object moves to the south during tracking, you can prevent the telescope tube from reversing.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eImportant information: Cannot be used on old SX mounts with the old blue star book\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eTechnical information\u003cbr\u003eCPU with 32-bit CISC processor 120 MHz\u003cbr\u003eThe unit is connected to the mount via a D-SUB 9PIN connector as is the STAR BOOK TEN.\u003cbr\u003eIt has a 6-pin, 6-wire modular connector for external autoguider operation.\u003cbr\u003eSupported operating systems are Android 6 or higher, iOS 9.0 or higher, WLAN standard: IEEE 802.11b\/g\/n\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eSD103SII Telescope:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eObjective lenses: 103mm, multicoated\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e2-lens SD apochromat without spacer plates\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eFocal length: 795mm (f\/7.7)\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eNo more spikes on the stars\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eResolution and limiting magnitude: 1.13 arc seconds;
