The Telescope

Highly corrected 102mm triplet apochromat (three lenses) with a carbon fibre tube and 2.5'' HEXAFOC precision focuser.

Apochromats in the small and medium aperture range are unparalleled: the combination of portability, extremely high image contrast, and sharpness, along with excellent astrophotography capabilities, make these instruments unbeatable. Advances in glass manufacturing have made high-quality apochromats accessible to more buyers. With the new Explore Scientific FCD-100 CF Hex, this development has reached a new peak – the colour purity of this device sets new standards in this price range. The optical design achieves a polystrehl value of 0.97, a mark of excellent correction.

This outstanding apochromat is versatile: the fast f/7 focal ratio allows short exposure times in astrophotography, while the high image sharpness and excellent contrast enable both wide-field observations, such as of the North America Nebula or the Andromeda Galaxy, and sharp planetary observations. It is extremely light and compact – the dew shield can be slid in to save space. Modern glass and precise manufacturing make this a top-level observation tool, providing pure enjoyment. This telescope is highly recommended not only for travel but also for quick observations and astrophotography. The high-quality 2.5'' HEXAFOC focuser with 1:10 reduction completes the package – with a large free diameter of 65mm, there is no vignetting, even when using larger camera sensors.

The Mount

The iEXOS-100 is a high-quality astronomical mount with practical Wi-Fi GoTo functionality and the revolutionary EXPLORE SCIENTIFIC PMC-Eight™ tracking. It makes sky navigation, finding objects, and precise tracking easy. The control is operated via the free ExploreStars app for Windows, Android, and iOS, comfortably through your laptop or tablet. Additionally, the free ASCOM POTH Client from EXPLORE SCIENTIFIC (wired or wireless) is available for download, enabling you to work with virtually any sky software supporting the ASCOM standard.

Precise tracking and intuitive control
The German equatorial design of the iEXOS-100 allows for precise tracking, enabling observers to keep an object centred in the eyepiece for extended periods. This helps astrophotographers overcome typical long-exposure challenges, such as field rotation and star trails. The unique strength of the PMC-Eight™ system lies in its eight independently operating CPUs, offering excellent responsiveness, efficiency, and extremely accurate tracking to compensate for Earth's rotation. The intuitive user interface of the ExploreStars app makes telescope alignment and night sky navigation easy, providing interesting information about tens of thousands of celestial objects, which are regularly updated.

Versatile equipment for easy, universal use
Other advantages of the mount include easy-to-use axis clamps, a stepless polar height adjustment, and a polar alignment tunnel for quick alignment with Polaris. A built-in bubble level helps level the tripod. Multiple fluorescent elements on the mount and tripod make it easier to navigate in the dark. The attachment of optics is done via a standard GP dovetail, making the iEXOS-100 a universally applicable mount.

Vixen SX2WL A80Mf Telescope Set
​SX2WL A80Mf telescope set with mount, tripod and eyepiecesThe A80Mf refractor is an ideal entry-level model for astronomy beginners who value high quality. Thanks to the Vixen quality controls, the 80 mm lens impresses with its outstanding optical performance. Two Plössl eyepieces (6.3 mm and 20 mm) and a 90° star diagonal are already included in the scope of delivery.Explore the moon and the brighter planets with the A80Mf. On good nights, you can observe the rings of the planet Saturn and the two brightest cloud bands on Jupiter are also visible. If the weather permits, you can even see the large red spot on the planet. 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. 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 A80MfObjective lenses: 80 mm, achromat, coatedFocal length: 910 mm (f/11.4)Resolution and limiting magnitude: 1.45 arc seconds; 11.3Light gathering capacity: 131xDimensions and weight: (OD) 90 mm x (L) 860 mm; 3.3 kgViewfinder telescope: 6x24 mmAdapter and connections: 42 mm for T-thread; 31.7 mm connectionSupplied accessories: 31.7 mm zenith prism, PL20 mm and PL6.3 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 cableA80Mf refracting telescope31.7 mm zenith prism2 eyepieces: PL20mm and PL6.3mmTube ringsDovetail mount6x24 mm finder scopeSXG aluminum tripodSXG pier extension
