Modular designed multipurpose telescope, both for observing the sun in the H-alpha wavelength, as well as for night sky observations. Easy conversion between the different applications with a few simple steps. Excellent image quality due to 2-lens ED optics with 70mm aperture for night sky observation, and 60mm usable aperture for H-alpha solar observation.With innovative air pressure tuning system, high-quality 2 inch (50.8mm) Rack&Pinion (R&P) focuser, and B600 blocking filter.Solar observing in H-alpha:The LS60MT/B600 is a complete telescope for observing the sun in H-alpha light, with 60mm free aperture (no central obstruction) and 420mm focal length. The H-alpha wavelength is the most impressive way to observe the sun, showing protuberances at the sun's edge, filaments and flares on the surface, and much more. An internal Etalon filter achieves a bandwidth of <0.7 Angstrom with the innovative air pressure tuning system Pressure-Tuner. Tuning is done by slightly changing the air pressure in a pressure chamber inside the telescope. This changes the refractive index of the air, making it easy to tune to the H-alpha line. The pressure tuner guarantees a homogeneous image, without central obstruction, and a permanently protected Etalon without erosion. A set of collimating lenses installed in the telescope ensures best performance.Fine adjustment is achieved with a solid 2 inch Rack&Pinion focuser with 10:1 reduction.Blocking-filter is the B600. The B600 is good for visual solar observing. Also solar imaging is possible by cameras with small CCD chip. We recommend a LS60MT with B1200 blocking-filter by using cameras with middle or large sized CCD chips.The star diagonal in which the blocking filter is installed, is equipped as standard for 1.25 inch eyepieces and with a T2 camera connection.Observing the starry night sky:The H-alpha Etalon system can be removed from the telescope in a few easy steps thanks to its modular design. The 2-lens ED refractor can then be used as a normal telescope with 70mm aperture and 420mm focal length for observation and photography of the night sky. The ED Doublet lens will offer an excellent image. It can be used with a standard 2 inch zenith mirror or other accessories at the R&P focuser, the back focus is 135mm.With an additional Amici prism, the telescope can of course also be used during the day for nature and landscape observations.This makes the LS60MT, with its small dimensions and low weight, also an ideal travel telescope for all applications!More applications:With additionally available accessories the LS60MT offers even more possibilities!- Double-StackThe LS60MT telescope can optionally be upgraded with the additionally available double-stack filters LS50FHa or LS60FHa (part numbers 0550200 and 0550250). These filters will be simply screwed on the front of the LS60MT, no additional adapters are necessary. Thereby a bandwidth of <0.5 Angstrom is achieved for H-alpha solar observation. Therefore much more details on the solar surface will become visible.- Solar observing in White-LightIf the H-alpha unit has been removed, of course either a sun filter to be installed in front of the objective, or a Herschel-wedge at the focuser can be used to observe the sunspots in White-Light.- Solar observing in Ca-K wavelengthCertainly, the Ca-K filter modules from Lunt Solar Systems can also be used at the LS60MT to observe and photograph super-granulation and other effects visible in this wavelength on the sun.This makes the LS60MT a completely universal usable telescope!FEATURES2-lens ED refractor, FPL-51Aperture: 70mmUsable aperture in H-alpha: 60mm (no central obstruction)Focal length: 420mmBandwidth: internal Etalon with <0.7 AngstromTuning: air pressure tuning system Pressure-TunerBlocking filter: B600 with 1.25 inch and T2 connectionFocuser: Rack&Pinion focuser with 10:1 reductionTube-ring with 1/4-20 tapped base (standard thread for photo-tripods)Weight with H-alpha unit: 3.8kgWeight without H-alpha unit: 2.6kgLength with H-alpha unit and blocking filter: 40cmLength without H-alpha unit: 31cmSCOPE OF DELIVERYLS60MT Multipurpose TelescopePressure-TunerB600 blocking filter in star-diagonal housing2 inch Rack&Pinion focuserTube ring with 1/4-20 connection for mounting on photo-tripodsTransport case (53x33x17cm)Instruction manual

Complete SXD2WL R200SS Newton Telescope Set with GoTo Mount, Tripod and EyepiecesThis high-quality Newton telescope set impresses with its large 200 mm aperture and fast f-ratio for photography. The telescope is manufactured in Japan and scores with its excellent workmanship, sharpness, and contrast performance. The advantage of this telescope lies in its low weight and short focal length. Thus, it is perfectly suited for large deep-sky objects.You will be amazed when observing the moon's surface with its craters or Saturn with its ring system. On Jupiter, in a good night many small details in the cloud bands will be visible, such as the Great Red Spot on the planet. In moonless nights, you can observe the Andromeda Nebula, Orion Nebula, Eagle Nebula, Lagoon Nebula and many other interesting fainter objects. The brighter globular clusters can also be easily resolved into individual stars.The fast f/4 ratio makes this telescope perfect for photography. With it, you can quickly achieve a great photo and don't need endlessly long exposure times. Optimise the image quality with the optional flattener Art. No. X000150. This flattener optimises the image up to the corners of a full-frame DSLR camera. The large 60 mm eyepiece drawtube of the telescope also allows for mounting heavy cameras without tilting. The stable metal tripod allows for a vibration-free setup of the telescope and mount even in windy weather.The SXD2WL mount is easily operated via a Wifi module with a smartphone or tablet. The user-friendly control of the mount is available through the free STAR BOOK Wireless app. This enables you to utilise practical features of celestial navigation, such as automatic GoTo swivelling 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%. This makes longer astronomical observations and astrophotography possible. When you tap the desired celestial object from a list, it automatically swivels into the telescope's field of view, and tracking begins. An existing STAR BOOK TEN controller 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 introduces a new standard of performance and precision in the Vixen mount family. The cross of axes of the mount has a photographic carrying capacity of 15 kg while weighing only 9.2 kg, making it excellent for mobile observations. Additionally, the motors located in the lower part of the mount also serve as counterweights. This means that the mount requires fewer weights for balance. Details of the SXD2 Mount Precision stepper motors and Micro-Step Motion Control System The heart of the SXD2 is the precision stepper motors, offering better performance and response than previous models. The Micro-Step Motion Control System features powerful yet very quiet drive properties, suitable for both fine movements and rapid swivels. 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. As a result, the motors move much quieter than in previous models. High-precision worm gears Advanced manufacturing technologies have eliminated errors in worm gear drives. The edges of both the worms and worm gears are exceptionally smooth, allowing very precise tracking. Declination axis as counterweight The massive motor units are built into the lower part of the declination axis, lowering the centre of gravity of the SXD2 right below the intersection of the RA and DEC axes. This reduces the need for 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, about 0.8 degree per turn. Built-in PFL-II polar finder with lighting The built-in 5x20 mm polar finder with a 10° field of view has a 3-star alignment system. This eliminates the tedious setting of date and time. The illuminated reticle with variable brightness and automatic shutdown is adjustable in 8 stages and illuminated in red. The alignment accuracy is 3 arc minutes. Details of the Wireless Module The Vixen Wifi adapter for EQ mounts enables you to control your Vixen mount via a smartphone or tablet. With the smartphone app STAR BOOK Wireless (free), celestial navigation becomes easy and wireless. Thus, the app instantly turns your mobile device into a controller for the equatorial mount. The response delay of the mount, the biggest disadvantage of wireless connections, has been reduced to a level comparable to wired solutions. Reduced power consumption compared to traditional controllers with LCD monitor The power consumption of the mount is reduced by up to 20%, enabling longer observations than with traditional wired controllers such as the STAR BOOK TEN. Operation similar to the STAR BOOK TEN controller The STAR BOOK Wireless App is set up similarly to the STAR BOOK TEN controller. Depending on the star chart setting, it contains up to 259,000 celestial objects. Tap on 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 are retained. Convenient operation While looking through the telescope, you control the mount by swiping across the star chart in the app. Since there are no buttons, you simply glide your finger across the star chart to comfortably operate the mount. Comprehensive 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 provides a fairly accurate positioning of the mount. Aligning on three or more stars allows for very precise alignment of the mount for high magnifications. The objects are then precisely and centrally placed 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 next observation with the same settings. Individual adjustment options The app offers various individual settings like gear play compensation, red night mode, autoguider, variable GoTo speed, and LED brightness, similar to the STAR BOOK TEN controller. You can also set the timing of the objective tube reversal (Meridian Flip) as desired. 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 about the Wifi Module CPU with 32-bit CISC processor 120 MHz The unit is connected to the mount with a D-SUB 9PIN connector, just like with the STAR BOOK TEN. It features a 6-pin 6-wire modular connector for external autoguider operation.
