LUNT LS130MT/B1200 Multipurpose APO Telescope for Sun + Night-Sky

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. 3-lens apochromatic telescope with FPL-51 glass, 130mm aperture and 910mm focal length - excellent image quality for H-Alpha solar observation and also for observing the starry sky at night. With innovative air pressure tuning system, good 2 inch (50.8mm) R&P focuser, and B1200 blocking filter. Solar observing in H-alpha: The LS130MT/B1200 is a complete telescope for observing the sun in H-alpha light, with 130mm free aperture (no central obstruction) and 910mm 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 R&P focuser with 10:1 reduction. Blocking-filter is the B1200. The B1200 is good for visual solar observing. Also solar imaging is possible by cameras with small sensor chip. We recommend a LS130MT with B1800 blocking-filter by using cameras with middle or large sized sensor chips, at very large sensor chips the B3400 blocking-filter. 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. Then the 3-lens apochromatic refractor can be used as a normal telescope with 130mm aperture and 910mm focal length for observation and photography of the night sky. The FPL-51 triplet lens offers an outstandingly low colour aberration image. Common 2 inch star diagonals can be used at the R&P focuser of the telescope. Please note that the optionally available conversion kit 0551696 is only absolutely necessary for the LS130MT version with B3400 blocking filter if the telescope is also to be used at night. The conversion kit is not required for the versions with B1200 and B1800. More applications: With additionally available accessories the LS130MT offers even more possibilities! - Double-Stack The LS130MT telescope can optionally be upgraded with the additionally available double-stack module LS130MT/DSII (item number 0551690). The DSII system is a internal double-stack module with Pressure-Tuner. 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-Light If the H-alpha unit has been removed, of course either a sun filter can 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 wavelengthThe additionally available "LUNT Ca-K Filter Module for LS130MT" (item number 0551697) can be used on the LS130MT to observe and photograph super-granulation and other effects visible at this wavelength on the sun.

SXP2WL mount with AX103S apochromatic high-performance refractor in a complete setWith this complete telescope set, you can immediately start your hobby. It includes everything you need for astronomical observation: a powerful AX103S apochromat, the corresponding mount with automatic GoTo tracking, 2 SLV 20 and SLV 5 eyepieces, and a sturdy tripod. The SXP2WL mount is equipped with the PFL-II polar finder for quick and easy alignment using reference stars, as well as a WiFi adapter with the STARBOOK APP. This allows the telescope to automatically navigate to the objects you select. The AX103S apochromat has been optimized for astrophotography and provides a sharp image even to the corners of a full-frame DSLR camera. But the telescope is also ideal for visual observation, offering high-contrast images without chromatic aberrations. The AX103S Apochromat in DetailThe AX103S is a top-class ED apochromat from the Vixen Refractor series. The telescope is equipped with a Triplet SD lens, and there is a field flattener lens located at the rear. Additionally, the f/8.0 refractor includes a central ED lens in the objective, which reduces chromatic aberration to an absolute minimum.An optional Focal Reducer (not included) can reduce the aperture ratio to 1:5.6, allowing for faster results in astrophotography. The integrated field flattener ensures a sharp image all the way to the edge of the field of view – an essential requirement for high-quality images of celestial bodies.With the 60 mm ring on the focuser, you can use 2'' eyepieces with the telescope or attach a camera adapter.The AX103S has been specifically designed for photographic applications and corrected for full-frame photography. However, it is also a visual delight, particularly for observing the moon and planets.This excellent telescope is guaranteed to impress you for a lifetime! The SXP2WL Mount in Detail Stronger Mount HousingThe SXP2WL mount features larger bearings than previous models to increase accuracy and load capacity. Additionally, the mount housing is made of thicker material. To make the polar block even more stable, the axis cross is clamped firmly into a fork. Very Precise Tracking with P-PEC FunctionThe SXP2WL mount is supplied with the modern STAR BOOK TEN controller. It offers a P-PEC function for highly precise tracking. The term 'PEC' stands for Periodic Error Correction. This system corrects errors in the mechanics, caused by periodic inaccuracies in the gear system.The P-PEC function saves your correction data even after the power is switched off, so you don't need to re-enter the data each 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 used to transmit power from the motor. However, this design can introduce a certain amount of backlash between the gears.To avoid the inaccuracies caused by this, the SXP2WL mount features a belt drive system, which significantly reduces both backlash and drive noise. Additionally, the system responds faster to any necessary corrections. 16 BearingsThe mechanical parts of the SXP2WL mount include a total of 16 bearings. The RA axis uses a set of tapered roller bearings to achieve more stability for more precise tracking. Stable Polar Altitude Block for AlignmentThe SXP2WL mount uses the same fork as the heavier AXJ mount. This new design allows for quick and stable latitude adjustment. Easy and Accurate Polar Alignment Using Reference StarsThe 6x20 polar finder scope is pre-installed. This allows you to set up the polar alignment (for both the northern and southern hemispheres). The polar finder offers a variable illuminated reticle with an automatic shut-off feature. Brightness is adjustable in 8 levels, so you can tailor it to your individual needs. The polar finder is also equipped with a direct setting using three reference stars and can achieve an accuracy of up to 3 arcminutes. 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 dovetail mounting block. In addition, the threaded holes on the mount head allow the use of mounting rails from other manufacturers. Combination of Innovative, Elegant Design and User-Friendly OperationThe stable, rigid mount body with very precise tracking has been further optimized by the P-PEC function. The SXP2WL is a highly precise and easy-to-use mount that is sure to excite any astrophotographer or observer. Special Motor Mounting for Fewer CounterweightsThe heavy RA and DEC motor units are mounted in the lower part of the declination axis, so the centre of gravity of the axis cross is below the RA and DEC axis. This means the declination body acts as a counterweight. The flat mounting head also 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. It allows you to use all the counterweights of the SX and GP mount series. The counterweight bar is housed in the declination body. Accessory ShoeFor easy 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 enables you to control your Vixen mount via a smartphone or tablet. Using the free STAR BOOK Wireless smartphone app, you can navigate the skies without any cables. The app instantly transforms your mobile device into a controller for the equatorial mount. The response delay of the mount, which is often the main drawback of wireless connections, has been minimized to a level comparable to wired solutions. Reduced Power Consumption Compared to Conventional LCD ControllersThe power consumption of the mount is reduced by up to 20%, enabling longer observation periods compared to traditional wired controllers like the STAR BOOK TEN. Similar Operation to the STAR BOOK TEN ControllerThe STAR BOOK Wireless app is designed similarly to the STAR BOOK TEN controller, offering up to 259,000 celestial objects, depending on the star chart settings. Simply tap a celestial object in the object list and initiate GoTo slewing. The mount will automatically move to the selected target and bring it into the telescope's field of view. All the beloved features of the STAR BOOK TEN remain available. Comfortable OperationWhen looking through the telescope, you can operate the mount by swiping on the star chart in the app. With no buttons, you simply slide your finger across the star chart, making the mount easy to control. Extensive Astronomical Data IncludedIn addition to data on well-observed celestial objects like Messier objects, NGC objects, IC objects, the sun, moon, planets, comets, and dwarf planets, the app also includes data for other objects. High-Precision AlignmentAligning the mount with one or two stars will give you fairly accurate positioning. With three or more stars, you can achieve highly precise alignment for high magnifications. The objects will then be centered in the telescope’s field of view. Alignment information is saved and retained even when the device is powered off. If you leave the telescope in its current state after completing an observation, you can start the automatic installation with the same settings the next time. Customizable SettingsThe app offers similar customization options to the STAR BOOK TEN controller, including backlash compensation, night mode in red, autoguider support, variable GoTo speed, and LED brightness adjustment. You can also configure when the telescope tube will flip (meridian flip). Even when the object is moving south during tracking, you can prevent the telescope tube from flipping.

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 LS80MT to observe and photograph super-granulation and other effects visible in this wavelength on the sun.This makes the LS80MT a completely universal usable ED Apo telescope of very good quality!FEATURES2-lens ED APO refractor, FPL-53Aperture: 80mm (no central obstruction)Focal length: 560mmBandwidth: internal Etalon with <0.7 AngstromTuning: air pressure tuning system Pressure-TunerBlocking filter: B1200 with 1.25" and T2 connectionFocuser: R&P with 10:1 reductionTwo tube-ring with handleSol-Searcher installed inside handleDovetail bar at GP-level for astronomical mountsWeight: 4.95kgLength with blocking filter and dew-shield: 62cmLength without blocking filter and removed dew-shield: 50cmSCOPE OF DELIVERYLS80MT Multipurpose TelescopePressure-TunerB1200 blocking filter in star-diagonal housing2 inch R&P focuser with 10:1 reductionTube rings with dovetail bar and sol-searcherTransport case (78x33x23cm)Instruction manualConversion kit for observation of the starry night sky (0551330) not included!
