Warning notes
  • Safety instructions: There are certain dangers when observing the sun, regardless of the telescope used. Lunt-Solar-Systems places great emphasis on the safety of their products during manufacture. Your safety is the highest priority, and we ask that you carefully read the telescope manual before beginning solar observation. Please never disassemble the telescope! Never use it if it has been modified or damaged in any way! Always contact our customer service if you have any questions regarding the safety of your instrument. Never look at the sun with an unprotected eye or with a telescope not intended for solar observation! Never leave your telescope unattended while it is pointed at the sun! Other people who are unfamiliar with it might attempt to replace the block filter with another prism, unaware of how critical this filter is for safety. The components of Lunt-Solar-Systems telescopes are not interchangeable with those of other manufacturers. Lunt-Solar-Systems solar telescopes contain several different optical elements that have been precisely adjusted and mounted during manufacture. These systems require no maintenance. Never disassemble the telescope. Doing so will void the warranty, potentially leading to expensive repairs, and may cause future damage to your instrument, compromising your safety! Most Lunt-Solar-Systems telescopes and filters include a very sensitive optical component called an Etalon. These Etalons are built into the system to protect them as best as possible. Countless considerations have been made to ensure the best performance of this "heart" of every system, even under the daily stresses it inevitably faces, such as shocks and vibrations during transport or regular use. Nevertheless, it should never be dropped. Improper use of the telescope can damage the Etalon (not a warranty case) and render the system unusable until repaired. The instrument should always be stored in its original packaging or in the optional transport case (item number 0554010). Like any optical precision instrument, it should be stored in a dry environment. With proper care, you will enjoy your instrument for a lifetime!

LUNT LS80MT/B1200R&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. 2-lens ED Apo telescope with FPL-53 glass, 80mm aperture and 560mm focal length - very good 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 LS80MT/B1200 is a complete telescope for observing the sun in H-alpha light, with 80mm free aperture (no central obstruction) and 560mm 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 LS80MT with B1800 blocking-filter by using cameras with 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. With the additionally available conversion kit (item number 0551330) the 2-lens ED Apo refractor can then be used as a normal telescope with 80mm aperture and 560mm focal length for observation and photography of the night sky. The FPL-53 doublet lens offers an low colour aberration image. Common 2 inch star diagonals can be used at the high quality R&P focuser of the conversion kit 0551330.Please note that the optionally available conversion kit 0551330 is absolutely necessary if the telescope should be used at night.More applications:With additionally available accessories the LS80MT offers even more possibilities!- Double-StackThe LS80MT telescope can optionally be upgraded with the additionally available double-stack module DSII/SFPT (item number 0551395). The DSII system is a internal double-stack module. 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 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!

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 LS1.25HW 31.7mm (1.25'') Herschel Wedge
This Herschel wedge is designed for superior White-Light solar observing and imaging. It can be used with refracting telescopes up to 102mm aperture, with 1.25'' focuser. This complete system comes with installed ND3.0 filter.Herschel Wedges are used to observe the sun in White Light. Around 95% of the Sun's light is suppressed by the wedge's ceramic prism. The remaining sun light is dimmed further by a factory-installed ND3.0 grey filter. Lunt Solar Systems Herschel wedges are installed in a fully closed housing with integrated heat trap. No stray light can escape from this, therefore it is very safe method of observing our nearest star.The difference between Herschel-wedges and normal front mounted filters is that the filtering takes place just before the eyepiece or camera. This provides better contrast and sharpness of the solar image - with more surface detail visible as a result.  Furthermore, a Herschel wedge is inherently safer than at a front mounted filter. A Herschel wedge can not rip or become punctured like a foil filter can be and it cannot become detached from the telescope objective accidentally.Only for use with refractor telescopes up to 102mm aperture:Because the full energy and heat of the sun inside the telescope, we advise solely using refractors for Herschel-wedge use. The refractor must not have corrector lenses at the back. Optical elements like corrector lenses, or secondary mirrors of reflecting telescopes, could suffer from thermal build-up by concentrated solar energy and could be permanently damaged.Tuning the brightness:Because the Herschel-wedge produces polarised light, you can use a normal polarising filter at the eyepiece, or camera-adapter. By turning the polarising filter the image brightness can be varied to the user's liking.This additional Polarising filter is not included. We recommend the BRESSER 1.25'' polarising filter, no: 4946464.FEATURESFor refractor telescopes up to 102mm apertureConnection to telescope: 1.25''Connection to eyepiece: 1.25''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 installedWHAT'S INCLUDEDHerschel-wedge for 1.25'' focuserIntegrated ND3.0 filterTransport caseInstruction manual

LUNT LS100MT/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-53 glass, 100mm aperture and 714mm 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 LS100MT/B1800 is a complete telescope for observing the sun in H-alpha light, with 100mm free aperture (no central obstruction) and 714mm 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 very good for visual solar observing. Also solar imaging is possible by cameras with small to large sensor chip. We recommend a LS100MT with B3400 blocking-filter by using cameras with very large 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. With the additionally available conversion kit (item number 0551430) the 3-lens apochromatic refractor can then be used as a normal telescope with 100mm aperture and 714mm 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 a internal double-stack module. 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 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 highest quality!

LUNT LS50THa/B600PT H-alpha solar telescope
A very compact, complete telescope for observing the sun in H-alpha light.The LS50THa solar telescope offers 50 mm free aperture, 350 mm focal length, and provides a bandwidth of <0.75 Angstrom. The telescope is fitted as standard with the air-pressure tuning system "Pressure-Tuner", the Etalon is safely installed inside the telescope. Prominences and surface detail can quickly be viewed spontaneously. This very portable system is an ideal travel companion for wherever you go.A B600 blocking filter is installed inside the star diagonal. The B600 offers a larger field of view than the smaller B400 and is very good for visual solar observing. Focusing is achieved by a non-roting Helical focuser.Please note that there is only a small back-focus at this telescope, therefore solar-imaging is very difficult. The LS50THa is designed for visual solar observing. We recommend for imaging the 60mm telescopes of the LS60MT series.Also double-stacking with a bandwidth of only <0.5 Angstrom is possible by using the additional available LS50C filter (0550210). This filter threads directly onto the LS50THa telescope. Double-stacking will provide much more contrast, and more details on the sun will become visible.FEATURESAperture: 50  mmFocal Length: 350 mmBandwidth: <0.75 AngstromTuning: air-pressure tuning system "Pressure-Tuner"Blocking Filter: B600non-rotating Helical focuserTube-ring with 1/4-20 tapped base (standard thread for photo-tripods)Length: 37cmWeight: 2.1kgSCOPE OF DELIVERYLS50THa H-alpha Solar TelescopeB600 Blocking Filter in star-diagonalPressure-TunerTube ring with 1/4-20 connection for mounting on photo-tripodsnon-rotating Helical focuserInstruction manual

BRESSER Full HD Deep-Sky Camera & Guider 1.25"
BRESSER Full HD Deep Sky Camera with autoguider: a great camera for different types of astrophotography and for autoguiding. Not only suitable for planets, but also for deep-sky objects such as galaxies, nebulae and star clusters. Dedicated ToupSky Astro Imaging software supports video preview, video recording, video processing, image capture and processing, dark field correction and raw data output. Easy to use, but with professional results. One of the main features of the new backlit SONY IMX290 CMOS sensor is its high light sensitivity, which makes it possible to detect deep-sky objects without active cooling. SONY has increased the quantum efficiency at 533 nm wavelength up to 77%, which is much better than other CMOS sensors have been able to achieve in the past. Connect this camera to a guidescope and attach the camera's built-in ST-4 port, directly to your telescope's equatorial mount guide port and autoguide - using many popular audioguiding programs (PHD, Guidedog and more). Autoguiding enables you to take accurate pictures with long exposure times of several minutes. Thanks to the extra light-sensitive camera, you now always have a suitable guide star to hand, even using short exposure times. An ST-4 protocol connection cable is also included. Simple automatic tracking at its best. You can use this camera with all guiding telescopes, or off-axis guiders that accept a 1.25 " tube, 1.25" filter thread (M28.5x0.6) or C-mount adapter thread (1 "x1 /32"). IMPORTANT NOTES: This is not a stand-alone guider camera. You always need a Windows 10/11 computer to take pictures and for autoguiding. The autoguider software is not included. You can use PHD2 Guiding, Guidedog, Metaguide, Guidemaster (freeware) or AstroArt, MaxIm DL (paid).

BRESSER StarTracker Astronomical Photo Mount PM-100
Do you already own a photo camera and would like to create impressive pictures of the night sky with the help of the long exposure or even make time-lapse pictures with little effort ? The BRESSER StarTracker Astronomical PhotoMount PM-100 is the ideal base. Not only for beginners in astrophotography, this mount is particularly well suited, but also the experts swear by a compact and easy-to-use mount to automatically compensate for the natural rotation of the earth. The built-in tracking motor rotates the saddle-mounted camera precisely against the earth's rotation and thus the stars remain in pinpoint shape even with long exposures. If you already own a sturdy photo tripod with a video tilt head you can use the photo mount's head directly with the 1/4 inch & 3/8 inch photo thread holes. The pole height (latitude) is then adjusted by the video tilt head. The photo-mount with tripod with carry-case and polar wedge are also available as a bundle - Product No.: 4964120 Which cameras are basically suitable for use with the BRESSER photo mount ? All cameras with ¼ inch (6.3mm) tripod connection thread and bulb length" B "for long exposure are suitable. The BRESSER StarTracker Astronomical Photo Mount PM-100 is designed for a camera with lens of max. 2.0 kg total weight to carry and track in polar mode. In Azimut mode also a camera weight up to 5.0kg is possible.  Large aperture, wide-angle lenses are ideal for the beginning, because the requirements for tracking accuracy accumulate with increasing focal length and exposure time. Thus, a shot with wide-angle lens can be exposed for up to several minutes and the stars remain punctiform without problems. For example, with a 200mm telephoto lens the polar alignment of the photo mount must be exactly right. But thanks to the integrated pole finder tunnel, this is done quickly. After setting up the light and compact StarTracker Photo Mount, simply set the approximate latitude (pole height) and aim Polaris through the integrated pole finder tunnel. Then mount the camera with the photo lens using the quick-release plate on the supplied ball head. With the ball head, the camera can be aligned and determined at any time on any section of the sky. As soon as the tracking motor is switched on, long-time exposure can be started immediately. This does not even take 5 minutes ... The tracking is carried out by a precise stepper motor, which can be controlled by an easy digital setup on LCD screen. Low power consumption allows up to 20 hours of operation with just one battery charge or simply use the micro USB port for an unlimited power supply. FEATURES Equatorial StarTracker Photo-Mount Automatic siderial tracking against the Earth rotation  Different tracking speed setting possible Suitable for northern and southern henisphere Time lapse: from 15 minutes to 48 hours Ballhead with quick release saddle plate and 1/4" Photo thread for Kamera mountingPhoto-Mount with 1/4" threaded bolt for ballhead mounting Additional quick release coupling for ball head removal High precision stepper motor with helical gear for accurate tracking Clear LCD screen and easy setup menu Battery operation 4 x AA batteries or mico USB (optional acc.)  Battery life: up to 20 hours Weight Photo-Mont: 0.63kg Load capacity of Photo-Mount: up to 2.0kg/5.0kg (EQ/AZ) Optional Acc: Polar-wedge, Tripod and carry-case, optical pole finder scope with illumination unit SCOPE OF DELIVERY StarTracker astronomical Photo-Mount head Ballhead with quick release saddle plate User manual
