Product information "LUNT LS130MT/B1800R&P 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 B1800 blocking filter.

Solar observing in H-alpha:
The LS130MT/B1800 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 B1800. The B1800 is good for visual solar observing and also solar imaging is possible by cameras with small to large sensor chips. We recommend a LS130MT with B3400 blocking-filter by using cameras with very large sized sensor 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. 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 wavelength
The 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.

This makes the LS130MT a completely universal usable apochromatic telescope of highest quality!

LUNT LS2HW 50.8mm (2'') Herschel-wedge
Herschel-wedge / Solar-wedge for superior White-Light solar observing and imaging. For refractor-telescopes up to 150mm aperture, and with 2'' focuser. Complete system with installed ND3.0 filter.Herschel-Wedges will be used to observe the sun in White-Light. Around 95 % of the sun light will be suppressed by the Herschel Wedge. The remaining sun light will be dimmed by a fix installed ND3.0 grey filter. Lunt Solar Systems Herschel-wedges are installed in a fully closed housing with integrated heat trap. There is no stray light escaping, therefore it is very safe.The difference between Herschel-wedges and normal front mounted filters is, that the filtering takes place just before the eyepiece or camera. This will provide a better contrast and sharpness of the solar image.Furthermore, there is more safety at a Herschel-wedge than at a front mounted filter. A Herschel-wedge can not rip or become holes like a foil. And also it can not drop down from the telescope objective accidentally.Only for use with refractor telescopes up to 150mm aperture:Because the full energy and heat of the sun will be inside the telescope, we advise to use only refractors with a Herschel-wedge. The refractor must not have corrector lenses at the back. Optical elements like corrector lenses, or secondary mirrors of reflector telescopes, become very hot by the concentrated solar energy and could be damaged.Tuning the brightness:Because the Herschel-wedge produce polarized light, you can use a normal polarizing filter at the eyepiece or camera-adapter. By turning the polarizing filter the brightness will be reduced.Polarizing filter not included. We recommend the BRESSER 2'' polarizing filter 4946465.FEATURESFor refractor-telescopes up to 150mm apertureConnection to telescope: 2''Connection to eyepiece: 2''90° housing like star-diagonalEspecially high-quality optical surfaces for very good contrastFully closed housing with integrated heat trapNo stray light escaping - therefore it is very safeThe needed ND3.0 filter is fix installedSCOPE OF DELIVERYHerschel-wedge for 2'' focuserIntegrated ND3.0 filterHardcaseInstruction manual

LUNT PCUSB Pressure-Tuner Controller with USB
Electronic Control unit with USB connection for one LUNT Pressure-Tuner system.The PC-USB is a microprocessor controlled pressure control system that can be retrofitted to any LUNT instrument (except LS50THa) with Pressure-Tuner (PT), without return to the Lunt facility. A simple air-pipe connects the PC-USB to the Pressure-Tuner. All existing PT systems (except LS50THa) can be retrofitted via an included adapter to the pressure tuner knob. The PC-USB can be used at any altitude.The PC-USB controller can be manually operated directly by the control panel at the housing, or via a computer by USB connection (Windows 7 or higher needed). A USB cable with USB-B plug is necessary for operating by a computer, this USB cable is not included. You will find the software for download on this webpage above at the tab "Manuals".Upon power up the PC-USB will go thru a systems vent and ambient pressure set mode. This will take around 60 seconds. The PC-USB is a simple 2 button system. One button for increasing and one button for decreasing the PT pressure. Digital feedback and indicator lights are provided. The PC-USB is accurate to 0.027 Bar (0.4 PSI), providing very precise control of the pressure setpoint. The PC-USB will auto-compensate for fluctuations in internal pressure changes due to significant changes in temperature. The PC-USB can be user programmed to center wavelength set point. Due to the sealed nature of the system, the center wavelength set point will remain constant at any altitude at a given set pressure point. Because the PC-USB can provide closed-loop feedback of internal etalon pressure users can correlate change in pressure to doppler shifted events.Normally the telescope shakes while you are tuning mechanically. Especially if you use high magnification, for example for observing the Doppler effect at a filament. With the PC-USB system there will be absolutely no shaking of the telescope while tuning at all magnifications, so observing Doppler shifted events will become more comfortable.The PC-USB can run continuously on internal battery power for more than 8 hours. It has external power input (15V DC) that can power the unit and charge the internal batteries simultaneously.SCOPE OF DELIVERYLUNT PC-USB Control SystemAdapter for PT knob3m air-pipeAC-adapter (with Euro-plug)Please note that this controller is not compatible with LS50THa series telescopes!

Vixen AXD2 with VMC 260 Maksutov-Cassegrain Telescope
AXD2 GoTo mount with VMC260L 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. The set includes a telescope, a mount with automatic tracking and a stable tripod. Featuring the STARBOOK TEN controller, 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 friends an exciting tour through the night sky! The AXD 2 mount in detail: Robust construction and lightweight housing with 30 kg load capacity (photographic) The RA and DEC axes are made using the A7075 superalloy, one the strongest aluminium alloys. 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 bearings The 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 motors Vixen 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 gears The sizes of the worm gears were increased in the latest Atlux version. The AXD mount has 270 teeth in the RA 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 backlash The 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 design The 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 layout The solid RA 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 scope The 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 correction Periodic 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 VMC 260 in detail The optics of the VMC260L are significantly better than the traditional Schmidt-Cassegrain telescope. Despite its high 3000 mm focal length, it is just 650 mm long. Featuring a large 260 mm aperture, the telescope collects large amounts of light for serious professional observations and photography of the planets and countless deep-sky objects. Thanks to the dielectric mirrors, the VMV260L guarantees razor-sharp images and maximum brightness. The open lens barrels cool the telescope quicker than conventional closed Cassegrain systems. The telescope can be used with an optional 0.62x focal reducer to reduce the aperture ratio to 1:7.1. This shortens the exposure times and allows you to photograph large objects. The telescope comes with a standard dovetail bar and a carry handle that doubles up as a camera holder for night sky photography.

EXPLORE SCIENTIFIC Ultra Light 20'' Dobson 500mm f/3.6 GENERATION II
Ultra Light Dobsonian 500mm GENERATION II - telescope mechanics handcrafted in HUNGARY and GERMANY No telescope type has influenced amateur astronomy as radically as the dobsonian telescope. Before the introduction of this telescope type by John Dobson the vast majority of amateur telescopes were small inadequate refractors on shaky mounts - just good enough to show the polar regions on mars or the rings of Saturn. Bigger telescopes, like the Schmidt-Cassegrain telescopes, were restricted to the relatively small group of amateurs that could afford them.The brilliant combination of simple - but effective - mechanics and the largest aperture available led to a worldwide triumph of this concept. No other telescope type offers you so much light for your money as a good dobson. We have taken the motto held together by gravity and driven by yoghurt power and offer a modern version of the classic - designed by amateur astronomers for amateur astronomers. Despite its large aperture the telescope can be transported easily even in small cars and is assembled within minutes without tools. The construction was optimized for maximum rigidity with a minimum of mass. The combination of big altitude wheels and a optimized aluminium-sandwich construction allows for small movements even at high magnifications. The focus position is already positioned to accept our coma-corrector (part No. 0510330) . The ideal workhorse for the deep-sky enthusiast. A telescope with 500mm aperture gathers more than 5100-times more light than the naked eye. Details on planetary surfaces stand out even to unexperienced observers, and countless deep-sky objects show details and some color. Bright globular clusters are resolved down to the core and the view of the lunar terminator will provide a unforgettable experience. The fast 20’’ f3.6 main mirror as well as the large 120mm secondary mirror are made of high quality quartz material, so the cooling time is reduced to a minimum and the Dobson is quickly ready for use. Every main mirror is delivered with an individual optical test certificate, which guarantees the highest capacity. A laser engraved center mark of the main mirror allows easy adjustment. The optical surface has a high-quality aluminum silvering with 94% reflectivity and an extremely resistant quartz protection layer. The mirror overcomes frequently occurring dew fogging and cleanups without any damages and guarantees a long service life. A complete redesign of this Dobson was necessary to ensure the significantly increased requirements to stiffness and load bearing capacity of the optical components. All connections of the tube structure were made in the TIG welding process and no rivets and screws were used. This has made it possible for us to produce this 20’’ light weight Dobson so unbelievably stiff in spite of the low weight - a noticeably good quality which is searching for its match. The production of almost all mechanical components is carried out by our partners in Hungary and the final assembly of the optics and subsequent quality control takes place in Rhede, Germany. The equipment details of the smaller Dobson models, which have been popular for years, have been taken over and even extended considerably. First of all, of course, the very good decomposability and transportability should be mentioned. Set-up and dismantling can be carried out without tools. The main and secondary mirrors are adjustable during the observation and only two adjusting screws have to be moved. Thanks to the use of precision ball-heads in the main mirror cell and a precision hinge for secondary mirror suppport, the adjustment is absolutely easy and guarantees excellent stability. All connecting parts of the tube trusses now consist of CNC machined aluminum and are attached by stainless steel dowel screws. The secondary mirror can now also be adjusted by the adjusting screws in the direction of the optical axis. The tried and tested 2.5’’ HEXAFOC focuser with 1:10 fine adjustment has been used for years - this allows vignetting-free observation despite the fast aperture ratio. A second 40° displaced installed mounting plate with a viewfinder shoe allows the rotation of the tube top in combination with a favorable position of the viewfinder tube or the mounting of an additional TELRAD viewfinder. The 6 supporting feet underneath the rockerbox offer a perfect stability and guarantee a smooth tracking in azimuth. Four smaller fans are installed in the side of the mirror box as well as a large fan is installed under the main mirror. This allows an even quicker adaptation to the ambient temperature and reduces the tube seeing (boundary layer removal). The lateral altitude wheels can now be stowed comfortably in the foam layers of the mirror box. Last but not least another gimmick: The optical tube and the mirror cell are designed to use also on heavy equatorial mounts.

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

LUNT LS100MT/B3400R&P 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-53 glass, 100 mm aperture and 714 mm 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 (50.8 mm) R&P focuser, and B3400 blocking filter. Solar observation in H-alpha: The LS100MT/B3400 is a complete telescope for observing the sun in H-alpha light, with 100 mm free aperture (no central obstruction) and 714 mm 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 B3400. The B3400 is good for solar imaging by cameras with very large sensor chips and can also be used for visual solar observing. The B3400 blocking filter is permanently installed inside the 2 inch R&P focuser. Common 2 inch star diagonals or other 2 inch accessories can be used. 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. With the additionally available conversion kit (item number 0551430) the 3-lens apochromatic refractor can then be used as a normal telescope with 100 mm aperture and 714 mm focal length for observation and photography of the night sky. The FPL-53 triplet lens offers an outstandingly low colour aberration image. Common 2 inch star diagonals can be used at the high quality R&P focuser of the conversion kit 0551430. Please note that the optionally available conversion kit 0551430 is absolutely necessary if the telescope should be used at night. More applications: With additionally available accessories the LS100MT offers even more possibilities! - Double-Stack The LS100MT telescope can optionally be upgraded with the additionally available double-stack module DSII/SFPT (item number 0551395). The DSII system is an internal double-stack module. Thereby a bandwidth of <0.5 Angstrom is achieved for H-alpha solar observation. Thus 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 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 wavelength Certainly, the Ca-K filter modules from LUNT Solar Systems can also be used at the LS100MT to observe and photograph super-granulation and other effects visible in this wavelength on the sun. This makes the LS100MT a completely universal usable apochromatic telescope of the highest quality! FEATURES 3-lens APO refractor, FPL-53 Aperture: 100 mm (no central obstruction) Focal length: 714 mm Bandwidth: internal Etalon with <0.7 Angstrom Tuning: air pressure tuning system Pressure-Tuner Blocking filter: B3400 with 2 inch connection Focuser: R&P with 10:1 reduction Two tube-ring with handle Sol-Searcher installed inside handle Dovetail bar at GP-level for astronomical mounts Weight: 6.8 kg Length with dew-shield: 78 cm Length with removed dew-shield: 65 cm SCOPE OF DELIVERY LS100MT Multipurpose Telescope Pressure-Tuner B3400 blocking filter installed inside focuser 2 inch R&P focuser with 10:1 reduction Tube rings with dovetail bar Transport case (78 x 33 x 23 cm) Instruction manual Conversion kit for observation of the starry night sky (0551430) not included!
