EXPLORE SCIENTIFIC ED APO 127mm f/7.5 FCD-100 CF HEX
Highly corrected 127mm air-spaced triplet apochromat (with three lenses) and carbon fibre 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 excellent astrophotographic performance 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 CF 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: its reasonably fast f-ratio makes for short exposure times when imaging deep sky objects, but it is still of a significant focal length, making higher power planetary and lunar observation comfortable without having to use really high magnification eyepieces. 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 come together to deliver a telescope that offers observing and imaging at the highest level. The Carbon Fibre construction allows this telescope to be used on lower capacity mounts, increasing convenience and portability. Although there are smaller instruments available, the combination of aperture and optical excellence at such a low weight and compact tube makes this an excellent travel scope. The well-designed 2.5" HEXAFOC focuser with 10:1 reduction is perfect for both visual and astrophotographic use - the large inner diameter of 65mm prevents vignetting by the focuser when the telescope is used for astrophotography with large sensors (full frame and above).We offer the very popular EXPLORE SCIENTIFIC Triplet ED APO Refractors in 3 different product lines:Essential Line: HOYA FCD-1 Glass lens, AL-Tube, 2.0" Rack & Pinion Focuser with 1:10, 2.0" Star Diagonal 99% Reflectivity (see Part No. 0112084(AL), 0112106(AL), 0112132(AL)), 0112155(CF + 3"FT)). Professional Line: HOYA FCD-100 Glass lens, AL/CF-Tube, 2.5" HEXAFOC Focuser with 1:10, 2.0" Star Diagonal 99% Reflectivity (see Part No. 0112086(AL), 0112108(AL), 0112109(CF), 0112134(AL), 0112135(CF))High-End Line: OHARA FPL-53 Glass lens, Carbon(CF) Tube, 3.0" Feather-Touch Focuser with 1:10, 2.0" Star Diagonal 99% Reflectivity (see Part No. 0112165(CF))SPECIFICATIONSAperture: 127mmFocal Length: 952mmFocal ratio: f/7.5Design: Apochromat with three lenses, two air spaces and FCD-100 glassWeight: 5.2kg, lightweight due to carbon fibre tubeBackfocus: 150mm above 2" adaptorHybrid viewfinder shoe to accept different viewfinder holdersWHAT'S INCLUDED Optical tube with retractable dew-shield2.5" HEX focuser with 1:10 gear reduction  2" Star Diagonal 99% reflectivityTube rings with dovetail plate and handle Extension tubes for focuser (2pcs)Dust caps for front-lens and focuserHybrid viewfinder shoe

AXD2 Goto Mount with AX103S Apochromat
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 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 kitMount 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 TR102 tripodTotal weight: 55.3 kgDELIVERY CONTENT AX103S apochromatTR102 tripod AXG half-pier 2 counterweights (1.5 kg and 7.0 kg) 7x50 finder scope Folding mirror Carry handle

Vixen SXD2WL AX103S Telescope Set
Complete Telescope Set SXD2WL AX103S with Wifi-GoTo Mount, Tripod, and Eyepieces This high-quality apochromatic refractor telescope set impresses with its intricate 103mm Triplet ED lens construction. The telescope is made in Japan and stands out for its excellent workmanship, sharpness, and contrast performance. The advantage of this APO refractor lies in its short build length and the completely corrected, edge-sharp optics. The AX103S is a top-class ED apochromat in the refractor range. It offers a Triplet ED lens and, in the rear area, a field flattener lens. The f8.0 refractor is equipped with a central ED lens in the objective and reduces chromatic aberration to an absolute minimum. An optional focal reducer can decrease the aperture ratio to 1:5.6 to achieve quicker results in astrophotography. The Vixen telescope belongs to the new Generation II with improved temperature-resistant lens cell. The integrated field flattener lens ensures a sharp image right to the edge of the field of view, which is very important in astrophotography. The AX103S is specifically developed for photographic purposes, but also visually a real highlight, especially for observing the moon and planets. You will be thrilled when you observe the moon's surface with its craters or Saturn with its ring system. On Jupiter, on a good night, the two bright cloud bands and many smaller details will be visible, as well 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 other interesting objects. But even weaker celestial objects become visible with this large aperture under a good sky. This telescope set “Made in Japan” simply leaves no wishes unfulfilled. The AX103S is corrected up to full-frame photography and delivers razor-sharp images right into the corners of the image field. The large 60mm eyepiece drawtube also allows for attaching heavy cameras without tilting. Furthermore, the supplied flip mirror enables comfortable observing even in challenging viewing situations and additionally offers a T2 thread for connecting a DSLR camera. Thus, you can observe in straight view or at a 90° angle. The carrying handle attached to the tube clamps ensures a safe transport of the telescope. The dew cap can be retracted for transport or storage. The sturdy metal tripod allows for vibration-free mounting of the telescope and mount even in windy weather. The SXD2WL mount is simply operated via a Wifi module with a smartphone or tablet. For user-friendly control of the mount, the free STAR BOOK Wireless app is available. This allows you to use practical features of celestial navigation such as automatic GoTo slewing to specific celestial objects very easily via your smartphone or tablet. As 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%. Thus, astronomical observations and astrophotography are possible over longer periods. By tapping the desired celestial object from a list, it is automatically slewed into the telescope's field of view and tracking begins. An existing STAR BOOK TEN control can also be used on this mount without any problems. Equipped with the same precision stepper motors as the flagship model, the AXD mount, the SXD2WL brings a new standard of performance and precision into the Vixen mount family. The axis cross of the mount has a photographic carrying capacity of 15 kg for only 9.2 kg and is thus excellently suited for mobile observations. In addition, the motors located in the lower part of the mount also serve as a counterweight. This means the mount needs fewer weights for balancing. The SXD2 Mount in Detail Precision stepper motors and Micro-Step Motion Control System The heart of the SXD2 are the precision stepper motors, which offer better performance and response than previous models. The Micro-Step Motion Control System is characterised by powerful yet very quiet drive properties, both in fine movements and in fast slews. Built-in bearings The bearings of the RA and DEC axes and the worm shafts have been significantly improved to reduce the load on the motors. This allows the motors to move much more quietly than in previous models. High-precision worm gears High-precision manufacturing technologies eliminate errors in the worm gears. The edges of both worms and worm gears are particularly smooth, allowing for very precise tracking. Declination axis as counterweight The massive motor units are built into the lower part of the declination axis, so that the centre of gravity of the SXD2 is below the intersection point of the RA and DEC axes. This means you need fewer additional counterweights. Latitude adjustment The latitude is adjustable between 0 and 70 degrees (divided into 3 zones and adjustable +/- 15 degrees per zone, for high, medium, and low latitudes); latitude scale in 2-degree steps; fine adjustment with a tangent screw head, approx. 0.8 degrees per rotation. Built-in PFL-II polar finder with illumination The built-in 5x20mm polar finder with 10° field of view features a 3-star alignment system. This eliminates the need to set date and time. The illuminated reticle with variable brightness and automatic shutdown is adjustable in 8 stages and illuminated in red. The adjustment accuracy is 3 arc minutes. The Wireless Module in Detail The 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), you can perform celestial navigation without any wiring. Thus, the app instantly transforms your mobile device into a control for the equatorial mount. The response delay of the mount, considered the biggest disadvantage of wireless connections, has been reduced to a level comparable to wired solutions. Reduced power consumption compared to conventional controls with LCD monitor The power consumption of the mount is reduced by up to 20% and thus allows longer observations than with conventional wired controls like the STAR BOOK TEN. Operation similar to STAR BOOK TEN control The STAR BOOK Wireless app is designed similarly to what you already know from the STAR BOOK TEN control. It contains up to 259,000 celestial objects depending on the star chart settings. Tap a celestial object in the object list and start the GoTo. The mount now automatically moves to this target and brings it into the field of view of the telescope. All popular features of the STAR BOOK TEN remain available. Convenient operation While looking through the telescope, you control the mount by swiping on the star chart of the app. Since there are no buttons, you simply slide your finger over the star chart, allowing you to conveniently operate the mount. Extensive astronomical data included This includes data on easily observable celestial bodies such as Messier objects, NGC objects, IC objects, as well as the sun, moon, planets, comets, and dwarf planets. High-precision alignment Alignment on one or two stars already gives you quite an accurate positioning of the mount. By aligning with three or more stars, a very precise alignment of the mount for high magnifications can be carried out. The objects are then positioned exactly and centrally in the field of view of your telescope. The alignment information is saved and can also be retained when the device is turned 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. Individual Adjustment Options The app offers various individual settings such as gear backlash compensation, red night mode, autoguider, variable GoTo speed, and LED brightness, just like the STAR BOOK TEN control. You can also set the timing of the objective tube reversal (Meridian Flip) according to your wishes. Even if the object moves south during tracking, you can prevent the telescope tube from reversing. Important Information Not usable on old SX mounts with the old blue Star Book Technical Information on the Wifi Module CPU with 32-bit CISC processor 120 MHz The unit is connected to the mount with a D-SUB 9PIN connector as with the STAR BOOK TEN. It has a 6-pin 6-wire modular connector for external autoguider operation.
