SXD2-SD103S complete telescope set

SXP2WL mount with fast R200SS reflector telescope (f4) in a complete set for professional astrophotographersWith this telescope set, you can start your exciting hobby immediately. It includes everything you need for astronomical observation: the powerful Newtonian telescope, an automatic mount with tracking and GoTo function, a tripod, and two eyepieces. The SXP2WL mount is equipped with the PFL-II polar finder for quick and easy alignment using reference stars as well as a Wifi module for wireless operation with a smartphone or tablet. This way, your telescope will automatically move to the objects you have selected. Over 259,000 celestial objects are already stored in the STAR BOOK APP. The R200SS Newtonian with its very short f4 focal ratio was optimized for photography and delivers sharp and high-contrast images. This bright and fast f-ratio allows you to capture breathtaking images of galaxies, nebulae, and star clusters in a short amount of time. This telescope is also perfect for comet hunting. It is also ideal for visual observation with its sharp images without chromatic aberration. You will be thrilled when you take a look at the Moon's surface with its many craters or observe Saturn with its rings. The SXP2WL mount is easily operated via a Wifi module with a smartphone or tablet. The free STAR BOOK Wireless app is available for user-friendly mount control. With this, you can easily use practical sky navigation functions like automatic GoTo slewing to specific celestial objects through your smartphone or tablet. Because 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 %. This enables longer periods of astronomical observations and astrophotography. Selecting a celestial object from a list will automatically move it into the telescope's field of view, and tracking will begin. An existing STAR BOOK TEN controller can also be used with this mount without problems. Equipped with the same precision stepper motors as the top model, the AXD mount, the SXP2WL brings a new standard of performance and precision to the Vixen mount family. The cross-axis of the SXP2 mount, with its 17 kg photographic payload, weighs only 13.3 kg, making it excellent for mobile observations. Additionally, the motors mounted on the lower part of the mount also act as counterweights, requiring fewer additional weights for balance. Larger bearings are installed in the SXP2 mount than in previous models to improve accuracy and load capacity. The mount housing is also made of stronger materials. To make the polar block even more stable, the cross-axis is firmly clamped into a fork. The Vixen R200SS Reflector Telescope in Detail The highly light-gathering f/4 200 mm optics of the R200SS come with a parabolic primary mirror, delivering extremely sharp images without chromatic aberration. A special coating (state-of-the-art technology) provides the optimal surface for observing and photographing deep-sky objects. Vixen has developed a unique aluminum vacuum coating system that produces highly precise mirror surfaces. This revolutionary system allows greater precision through controlled coating of the primary mirror. This coating is also used in the Vixen VC200L. With its large aperture and short focal length, the R200SS telescope is ideal for astrophotography of nebulae, star clusters, and comets. When used with an optional coma corrector Art. X000150 (not included), it produces sharp images to the corners of a full-frame DSLR. The focuser features a 60 mm thread, allowing you to use 2-inch eyepieces with the appropriate adapter. The SXP2 Mount in Detail Stronger Mount HousingIn the SXP2 mount, larger bearings were installed than in previous models to improve accuracy and load capacity. Additionally, the mount housing is characterized by higher material thickness. To make the polar block even more stable, the cross-axis is firmly clamped into a fork. Very Precise Tracking with P-PEC FunctionThe SXP2 mount is delivered with the modern STAR BOOK TEN controller. It offers you the P-PEC function for particularly precise tracking. The abbreviation "PEC" stands for "Periodic Error Correction". The system corrects mechanical errors caused by periodic gear system inaccuracies. The SXP2 equatorial mount is equipped with a P-PEC function, which evolved from the PEC function. The P-PEC function saves your correction records even after the mount is powered off. This way, you don’t need to re-enter the data every time, allowing for faster operation and more precise tracking. Low-Noise Belt Drive System with Minimal PlayIn traditional motor-driven equatorial mounts, gears are used that are driven by the motor. However, this construction has the disadvantage of introducing some play between the gears. To avoid the resulting inaccuracies, the SXP2 mount features a belt drive system. This significantly reduces both gear play and motor noise. Furthermore, the device responds more quickly when corrections are required. 16 BearingsThe mechanical components of the SXP2 mount feature a total of 16 bearings. A set of tapered roller bearings is used for the RA axis to provide more stability for precise tracking. Stable Altitude Block for AlignmentThe SXP2 mount uses the same fork as the heavier AXJ mount. This new construction enables quick and stable latitude adjustment. Simple and Precise Polar Alignment Using Reference StarsThe 6x20 polar finder is pre-installed. This allows you to set polar alignment (for both the Northern and Southern Hemispheres). The polar finder provides a variable illuminated reticle with an automatic shut-off function. The brightness can be adjusted in 8 steps to suit your individual needs. Additionally, the polar finder features direct alignment using three reference stars and can achieve an accuracy of up to 3 arc minutes. Variable Mount HeadThe mount head has a diameter of 35 mm and eight threaded holes for M8 screws, arranged at 45-degree intervals. An optional accessory plate can be attached directly or in combination with an optional mounting block for dovetail plates. Additionally, the threaded holes on the mount head allow for the use of rails from other manufacturers. Combination of Innovative, Elegant Design and User-Friendly OperationThe stable, stiff mount body with very precise tracking has been further optimized with the P-PEC function. As a result, the SXP2 is a highly accurate and easy-to-use mount that will thrill every astrophotographer and observer. Special Motor Mounting for Fewer CounterweightsThe heavy RA and DEC motor units are mounted in the lower part of the declination axis, positioning the center of gravity of the cross-axis beneath the RA and DEC axes. This way, the declination body acts as a counterweight. Additionally, the flat mount head allows 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. You can use it with all counterweights from the SX and GP mount series. The counterweight bar is housed within the declination body. Accessory ShoeFor simple and quick polar alignment, the #35511 Polar Meter can be slid onto this shoe. Latitude AdjustmentThe latitude can be adjusted between 0 and 70 degrees (divided into 3 zones and adjustable +/- 15 degrees per zone, for high, medium, 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. Using the free Smartphone App STAR BOOK Wireless, you can navigate the sky without cables. The app transforms your mobile device into a control system for the equatorial mount in no time. The response delay of the mount, which is typically the biggest drawback of wireless connections, has been reduced to a level comparable to wired solutions. Reduced Power Consumption Compared to Conventional Controllers with LCD MonitorThe mount's power consumption is reduced by up to 20%, enabling longer observations compared to conventional wired controllers like the STAR BOOK TEN. Operation Similar to the STAR BOOK TEN ControllerThe STAR BOOK Wireless App is similar to the STAR BOOK TEN controller. It contains up to 259,000 celestial objects, depending on the star chart settings. Tap an object in the list, and the GoTo process starts. The mount will automatically move the object into the telescope's field of view. All the popular features of the STAR BOOK TEN remain available. Comfortable OperationWhile looking through the telescope, you operate the mount by swiping on the app's star chart. With no buttons, you simply glide your finger across the star chart to comfortably control the mount. Comprehensive Astronomical Data IncludedIn addition to well-observed celestial bodies such as Messier objects, NGC objects, IC objects, the sun, moon, planets, comets, and dwarf planets, a vast amount of astronomical data is included. Highly Accurate AlignmentAligning to one or two stars gives you a reasonably accurate mount position. Aligning to three or more stars allows for highly accurate alignment for high magnifications. Objects will be positioned precisely and centrally in the telescope’s field of view. The alignment information is saved and can be retained even when the device is powered off. By leaving the telescope in its current position after finishing an observation, you can restart automatic installation with the same settings during your next observation. Customizable SettingsThe app, like the STAR BOOK TEN controller, offers various custom settings such as gear backlash compensation, night mode in red, autoguider support, and variable GoTo speed and LED brightness. You can also customize the timing of the tube flip (meridian flip) to your liking. Even if the object moves south during tracking, you can prevent the telescope tube from flipping. Technical Information about the Wifi Module32-bit CISC processor 120 MHz CPUThe unit connects to the mount via a D-SUB 9PIN connector like the STAR BOOK TEN.It has a 6-pin, 6-wire modular plug for external autoguider operation.Supported operating systems: Android 6 or higher, iOS 9.0 or higher, WLAN standard: IEEE 802.11b/g/n FEATURES SXP2WL MOUNT RA worm wheel: 73.2 mm Ø, brass wheel with 180 teeth DEC worm wheel: 73.2 mm Ø, brass wheel with 180 teeth Worm shaft: 9 mm Ø, brass RA & DEC axis: 40 mm Ø, carbon steel bearing, 16 bearings Counterweight bar: 20 mm Ø RA Polar scope: PF-LII 6x20 mm Stepper motors: 250 PPS speed, maximum 1000x Sidereal rate Maximum load: 17 kg photographic without counterweight Power connection: DC12V 0.45~2.2 A Dimensions: 386 x 419 x 128 mm Weight of cross axis: 13.3 kg without counterweight Counterweights: 3.7 kg, 1.9 kg FEATURES R200SS TELESCOPE Mirror: 200 mm (8 inches) Focal length: 800 mm Focal ratio: f4 Resolution and limit magnitude: 1.01 arcseconds, 13.3 mag Light-gathering power: 816x Dimensions and weight: 232 x 600 mm; 6.9 kg Adapters and connections: 31.7 mm sleeve, 60 mm thread SCOPE OF DELIVERY R200SS reflector telescope SXP2WL GoTo mount Wifi Adapter SXG-HAL130 tripod SXG half-pillar 2 counterweights: 1.9 kg and 3.7 kg 7x50 illuminated finder scope, 1.25-inch connection Carrying strap Dovetail rail Dovetail mount 2 eyepieces: SLV 20 mm and SLV 5 mm Illuminated polar finder PFL-II

SX2WL SD103SII complete telescope set with GoTo mount, tripod and eyepieces.This high-quality apochromatic refractor telescope set impresses with its 103 mm SD optics. The telescope is manufactured in Japan and scores 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, but also fainter celestial objects become visible with this large 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 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 thus reduces chromatic aberration across all colours.The 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 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 grip 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 SD103SIIObjective lenses: 103 mm, multicoated2-lens SD apochromat without spacer platesFocal length: 795 mm (f/7.7)No more spikes on the starsResolution and limiting magnitude: 1.13 arc seconds; 11.8Light gathering capacity: 217xDimensions and weight: (OD) 115 mm x (L) 810 mm; 5.5 kgFinder scope: 7x50 with illuminated reticleAdapter 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, SLV 20 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 cableSD103S II refracting telescopeFlip mirror2 eyepieces: SLV 20mm and SLV 5mmTube ringsDovetail mount7x50 finder scope  SXG aluminum tripod

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.

Highly corrected 127 mm air-spaced triplet apochromat (with three lenses) and aluminium tube and a 2.5'' high-precision HEXAFOC focuser. NEW: Now with hybrid viewfinder shoe to accept different viewfinder holders. Apochromats are the ultimate choice in small to medium-sized telescopes: the combination of compactness, transportability, very high image contrast and sharpness together with the possibility to make excellent astrophotos cannot be bested. The advances in glass manufacturing during the last few years have made true apochromats available to more astronomy enthusiasts than ever before. The new Explore Scientific FCD-100 Alu Hex represents another major improvement in this field - the overall correction (colour and spherical) is setting new standards in this price class. The optical design shows a polystrehl value of 0.97 indicating a level of correction that is absolutely top of the line. This excellent apochromat is a very versatile telescope: the fast f-ratio makes short exposure times possible. The high contrast and sharpness of the image provide breathtaking views of large objects like the North America nebula or the Andromeda Galaxy, as well as tack sharp planetary images. The telescope is lightweight and compact - the dew shield slides down the tube to minimize size for transportation. Revolutionary glass and precision manufacturing created a telescope that offers observing joy on the highest level.
