Vixen AP-SD81S II Telescope set

SX2WL SD81SII complete telescope set with mount, tripod and eyepieces.This high-quality apochromatic refractor telescope set impresses with its 81 mm SD optics. The 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 ring system. On a good night, the two bright cloud bands and many smaller details, such as the large red spot on the planet, will also be visible on Jupiter. On moonless nights you can observe the Andromeda Nebula, Orion Nebula, Eagle Nebula, Lagoon Nebula and many other interesting objects. In addition, fainter celestial objects become visible with this aperture under a good sky. This telescope set "Made in Japan" simply leaves nothing to be desired. The FPL53 glass used in the telescope reproduces an extremely clear and sharp image thanks to an extraordinarily high elimination of residual colour errors. 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 thus reduces chromatic aberration across all colours. The new Vixen SD81SII no longer uses spacer discs, which leads to significantly better image quality, especially with bright stars. Photographic images therefore no longer show spikes on the stars, which 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 44 mm 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 60 mm focuser also allows heavy cameras to be attached without tilting. Furthermore, the supplied folding mirror allows comfortable observation even in unfavourable observation situations and also offers a T2 thread for connecting a DSLR camera. This allows you to observe in a degree view or at a 90° angle. The carrying handle attached to the tube clamps ensures a secure hold when transporting the telescope. The sturdy metal tripod enables the telescope and mount to be mounted without vibration, 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. 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 retainedConvenient operationWhen 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 includedIn 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 alignmentBy 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.Individual setting optionsAs with the STAR BOOK TEN controller, the app offers various individual settings, such as gear backlash compensation, night mode in red, autoguider, variable GoTo speed and LED brightness. You can also set the timing of the reversal of the objective tube (meridian flip) as required.Even if the object moves to the south during tracking, you can prevent the telescope tube from reversing.Important information: Cannot be used on old SX mounts with the old blue star bookTechnical informationCPU with 32-bit CISC processor 120 MHzThe unit is connected to the mount via a D-SUB 9PIN connector as is the STAR BOOK TEN.It has a 6-pin, 6-wire modular connector for external autoguider operation.Supported operating systems are Android 6 or higher, iOS 9.0 or higher, WLAN standard: IEEE 802.11b/g/n・FEATURESTelescope SD81SIIObjective lenses: 81 mm, multicoated2-lens SD apochromat without spacer platesFocal length: 625 mm (f/7.7)No more spikes on the starsResolution and limiting magnitude: 1.43 arc seconds; 11.3Light gathering capacity: 134xDimensions and weight: (OD) 90 mm x (L) 585 mm; 3.6 kgXY Red Dot Finder IIAdapter and connections: 60 mm thread, 50.8 mm and 31.7 mm connection, T-ring threadSupplied accessories: Flip mirror with 50.8 mm and 31.7 mm connection, SLV20 mm and SLV 5.0 mm eyepiecesPhotography: primary focus and eyepiece projectionSturdy metal focuserSX2WL mountRA Gear rim: 180 teethDEC gear rim: 180 teethBearing: Carbon steel / Decl. 35 mm, RA 40 mm thicknessFine height adjustment: 0° to 70°, (fine adjustment +/- 15°, height)Counterweight rod: 20 mm diameterAzimuth adjustment: Fine worm adjustmentPower supply: DC12 V; 0.4~1.7 AMaximum load: 12 kg, photographic, without counterweightCounterweight: 1x 1.9 kgTripod connection: 45 mm spigotDimensions: 36 cm (H) x 12 cm (W) x 36 cm (L)Weight: 7 kg, without counterweight32-bit CISC processor 120 MHzOperating system: Android 6 or higher, iOS 9.0 or higherConnection: D-SUB 9PIN plugAutoguider input ST4Power consumption SXD2WL+Wireless unit: DC12V / 0.3-2.0 A (load 10 kg), 0.4-2.2 A (load 15 kg)SCOPE OF DELIVERYSX2WL mountWireless unitCounterweight: 1.9 kgMounting toolCigarette lighter cableSD81SII refracting telescopeFlip mirror2 eyepieces: SLV20mm and SLV5mmTube ringsDovetail mountXY Red Dot Finder IISXG aluminum tripod

AXD2 GoTo mount with AX103S telescope set The AXD2 mount comes with the new STARBOOK TEN controller and the PFL polar viewfinder, which allows you to configure the mount quickly and easily via reference stars.This telescope set has everything that you need for hobby astronomy.It includes a telescope, a mount with automatic tracking and a sturdy tripod. Featuring the STARBOOK TEN control system, the telescope locates celestial objects automatically so that you don't need to search for them manually.Even if you're not an expert, you can still give your friendsan exciting tour through the night sky! The AXD2 mount in detail:Robust construction and lightweight housing with 30 kg load capacity (photographic)The A7075 superalloy, the strongest aluminium alloy, is used for the R.A. and DEC axes. The stability of the A7075 superalloy is stronger than titanium, which is known for its strength as a lightweight material. Its thickness is 38% less than titanium. Using the A7075 superalloy for the axes ensures that the AXD mount is both lightweight and stable.21 bearingsThe rotating parts of the AXD mount have a total of 21 bearings. These ensure uniform motion in order to swivel the telescope and track objects.Stepper motorsVixen uses precise stepper motors for the mount in order to ensure optimal performance. The motors are controlled via a micro-step motion control system, which eliminates the disadvantage of stepper motors with large steps. The system generates 400 impulses per second at a high speed. This results in very quiet scanning with no vibrations. The stepper motors on the AXD mount have sufficient torques. This is most significant when working at high magnifications and photographing with a CCD camera with small pixel sizes.Worm gearsThe sizes of the worm gears were increased in the latest Atlux version. The AXD mount has 270 teeth in the R.A. axis and 216 teeth in the DC axis. Both axes are 50 mm in diameter. This ensures that the mount operates with precision and stability.Low backlashThe Vixen micro-step motion control system ensures that the stepper motors run uniformly at low and high speeds. This eliminates the need for reduction gears in the motor and therefore reduces the backlash in the gears.Elegant designThe flat sides of the mount were designed based on previous generations of the New Atlux range. The white and silver housing provides a modern and elegant exterior with high functionality.The AXD is the flagship model in the Vixen mount range.Original motor layoutThe solid R.A. and DEC motor units are arranged in the lower part of the mount. This means that they automatically act as a counterweight. As a result, you require far fewer weights on the counterweight bar. On small devices, no counterweight is required. The counterweight bar can be slid fully into the housing.Polar finder scopeThe AXD mount is equipped with a 6x20 polar finder as standard. The polar finder features an integrated scale, which provides a quick and easy way to polar align the telescope in the northern hemisphere.For observations in southern latitudes, the polar finder features an image of the Octans constellation, which can be aligned with the night sky.VPEC periodic error correctionPeriodic errors on mounts are usually measured and corrected by the user. Unlike the old StarBook controller, the STAR BOOK TEN controller saves these errors permanently. The periodic error of the mount is measured in the factory and corrected before delivery. This is known as VPEC and functions automatically as soon as you use the mount.It delivers an accuracy of +/- 2.8 arc seconds. You can increase the tracking accuracy further by saving your own recorded periodic errors.The AX 103S in detail:The AX103S is a top-of-the-range ED apochromat in the refractor series.It was developed for photography, including full-frame cameras, and illuminates a 44 mm frame.It features a triplet ED lens and a rear-mounted field flattener lens.The f8.0 refractor contains a central ED lens in the objective and reduces chromatic aberration to an absolute minimum.An optional focal reducer can reduce the aperture ratio to 1:5.6 in order to provide quicker results for astrophotographers.The built-in field flattener lens provides a sharp image across the entire field of view - an essential requirements in astrophotography.The 60 mm ring on the focuser allows you to attach a 2'' eyepiece and a camera adapter.The AX103S is specially designed for photography, but also offers stunning visual performance, especially for observing the moon and the planets.This telescope is guaranteed to provide a lifetime of outstanding performance!FEATURESAXD2 GoTo mount with AX103S telescopeProfessional telescope kitTracking accuracy of +/- 2.8 arc secondsMount with 30 kg load capacity (photographic)Modern STARBOOK TEN controller with autoguider inputAXD 103S apochromat for full frame photographyIlluminated polar finder with direct star alignmentSturdy, vibration-resistant P85DX observatory pierTotal weight: 64.6 kgDELIVERY CONTENTTR102 tripod AX103S apochromatAXD2 GoTo mountAXG half-pier 2 counterweights (1.5 kg and 7.0 kg) 7x50 finder scope Folding mirror Carry handle

This telescope set has everything that you need for hobby astronomy. It includes a telescope, a mount with automatic tracking, a tripod and eyepieces. Featuring the STARBOOK TEN control system, the telescope locates celestial objects automatically so that you don’t need to search for them manually. Even if you’re not an expert, you can still give your friends an exciting tour through the night sky! The SXD 2 mount in detail With a combination of the best features from the Sphinx series and the all-new STAR BOOK TEN manual control, Vixen has developed a new generation of SX mounts for demanding observers and astrophotographers. The SXD2 mount comes with the new STAR BOOK TEN control and can be operated manually or with a computer. Featuring the same precision stepper motors as the top-of-the range AXD mount, the SXD2 sets a new standard for performance in the Vixen mount range. Compared with the SX mounts, the SXD2 has a quieter tracking system, and the increased precision of the motors provides better performance for the long exposure times used in astrophography. Precision stepper motors and micro-step motion control system The star feature of the SXD2 is the precision stepper motors, which offer better performance and responsiveness than previous models. The micro-step motion control system has powerful yet very quiet drive characteristics that offer both fine control and quick swivel movements. Built-in bearings The bearings of the RA and DEC axles and the worm shafts were significantly improved in order to reduce the load on the motors. The motors are much quieter than those on previous models. Robust RA and DEC axles High-precision and thick steel shafts in RA and DEC increase the robustness of the SXD2 mount. High-precision worm gears High-precision processing technologies were used to rectify problems with the worm gear. The edges of both worms and worm gears are particularly smooth, which enables them to deliver very high precision. Declination axis functions as counterweight The sturdy motor units are located in the lower section of the declination axis to ensure that the SDX2’s centre of gravity is below the intersection of the RA and DEC axis. As a result, fewer additional counterweights are required. The SD115S in detail The ED81SII, ED103S and ED115S refractors were originally designed for visual observers or photographers with an APS-C camera. The new SD series features new inner panels which are optimised for full-frame cameras and illuminates images with a frame size of 44 mm. The SD 115 ED refractor is the largest refractor in the Vixen range. Thanks to the FPL-53 lens, it offers an extremely high contrast and sharpness. This type of lens produces true colour and high-contrast images. Another advantage of the SD refractors is their very short length and lightweight design.
