Product information "LUNT LS40THa/B1200 H-alpha solar telescope"
Solar observation in H-Alpha: prominences, filaments, flares ... the most spectacular way to see the Sun - easy and affordable with the LS40THa.
Complete H-alpha solar telescope with 40mm aperture, <0.7 Angstrom bandwidth, B1200 blocking-filter, and Helical focuser.
The LS40THa/B1200 is a complete telescope for observing the sun in H-alpha, with 40mm aperture (no central obstruction) and 400mm 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 Etalon with mechanical tilt-tuning provides <0.7 Angstrom bandwidth.
Fine adjustment is achieved with a 1.25 inch Helical focuser. Blocking-filter is the B1200, this is excellent for visual observation of the sun. The star diagonal in which the blocking filter is installed, is equipped as standard for 1.25 inch eyepiece connection.
The easy handling makes this telescope ideal for starting H-Alpha solar observation. Due to its compact dimensions it is also a good travel telescope for the experienced solar observers.
The LS40THa telescopes are available with choice of B500, B600 or B1200 blocking filters. The larger blocking filters provide less edge obstruction and a larger field of view for visual observation and photography. Please note that these telescopes have only a very small back focus and therefore photography is difficult. We recommend special astro cameras for photography, which have a very short distance to the sensor, such as the BRESSER Full HD camera item number 4959050.

BRESSER Twilight I telescope mount with tripod
€299.00*
The Twilight I is a light-to-medium-duty alt-azimuth mount with tripod designed to quickly and easily accept small to medium sized refractors, such as the AR102 + AR127s or ED102mm + ED127, and of course, the ED80mm. Lightweight, fast Newtonians will also match up nicely with the BRESSER Twilight I mount. As long as your telescope does not exceed 18 pounds and has a Vixen-Style Universal Dovetail bar for mounting the telescope to the mount head, you are good to go. The Twilight I alt-azimuth mount head is made of powder-coated aluminum and there are worm gears on both axes. The adjustable angle head can be tilted forward or back at a 45° angle to allow more clearance for your telescope so you can point it straight up for viewing at the zenith. The Allen hex wrench for doing the mount head adjustment can be safely stored at the integrated magnetic holder. Slow-motion control cables are attached on the vertical and horizontal axes, and are easy to turn during the night, even with gloves on, due to the over-sized knurled knobs that are attached to the end of each cable. They can be attached to either side of each axis to accommodate right or left-handed users, or different types of telescopes (e.g. refractors vs. Newtonian reflectors) for ease of adjustment. The stainless steel tripod that comes standard with the Twilight I mount has adjustable legs and a wide foot print of 42 inches, which makes the tripod more stable. A spreader bar locks against the inside of the legs to secure the tripod even further, and keep vibrations to a minimum. SCOPE OF DELIVERYTwilight I Telescope MountStainless Steel Field tripod

LUNT LS40FHa H-alpha double-stack filter for LS40THa
€999.00*
Expected to be available from autumn / winter 2023
Double-stack filter for LS40THa telescopes.
The bandwidth of H-alpha systems can be reduced by so-called "double-stacking". A smaller bandwidth provides much more contrast at the solar surface, thereby many more details will become visible.
Double-stacking with a bandwidth of only <0.55 Angstrom is also possible at the LS40THa telescopes. Therefore Lunt Solar Systems has especially designed this LS40FHa double-stack filter in compact housing. The filter threads directly onto the LS40THa telescopes.

LUNT LS60MT/R&P Multipurpose Telescope OTA without Blocking Filter
€2,899.00*
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
and high-quality 2 inch (50.8mm) Rack&Pinion (R&P) focuser. Delivered without blocking filter,
use for H-Alpha sun observation only possible with additional blocking
filter!This telescope is supplied without blocking filter. We
offer a wide range of additionally available blocking filters in
different sizes, either mounted in a 90° star-diagonal housing or in a
straight extension tube. These are all usable with this telescope.ATTENTION: Without such an additional blocking filter you cannot use this telescope for H-alpha solar observation!Solar observing in H-alpha:The LS60MT is a 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.This version of the LS60MT is delivered without blocking filter.
Therefore an additional blocking filter is required to use the
telescope for solar observation in the H-alpha wavelength. You can
choose from the wide range of Lunt Solar Systems blocking filters and
decide for example if you want a blocking filter in a 90° star-diagonal
housing or one in a straight extension tube.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 at the R&P focuser.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-TunerSupplied without blocking filter, additionally available blocking filter absolutely necessary!Focuser: 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-Tuner2 inch Rack&Pinion focuserTube ring with 1/4-20 connection for mounting on photo-tripodsTransport case (53x33x17cm)Instruction manual

We offer a wide range of additionally available blocking filters in different sizes, either mounted in a 90° star-diagonal housing or in a straight extension tube. These are all usable with this telescope.ATTENTION: Without such an additional blocking filter you cannot use this telescope for H-alpha solar observation!Solar observing in H-alpha:The LS100MT is a 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.This version of the LS100MT is delivered without blocking filter. Therefore an additional blocking filter is required to use the telescope for solar observation in the H-alpha wavelength. You can choose from the wide range of Lunt Solar Systems blocking filters and decide for example if you want a blocking filter in a 90° star-diagonal housing or one in a straight extension tube.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-StackThe 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-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 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!FEATURES3-lens APO refractor, FPL-53Aperture: 100mm (no central obstruction)Focal length: 714mmBandwidth: internal Etalon with <0.7 AngstromTuning: air pressure tuning system Pressure-TunerSupplied without blocking filter, additionally available blocking filter absolutely necessary!Focuser: R&P with 10:1 reductionTwo tube-ring with handleSol-Searcher installed inside handleDovetail bar at GP-level for astronomical mountsWeight: 6.8kgLength with dew-shield: 78cmLength with removed dew-shield: 65cmSCOPE OF DELIVERYLS100MT Multipurpose TelescopePressure-Tuner2 inch R&P focuser with 10:1 reductionTube rings with dovetail barTransport case (78x33x23cm)Instruction manualConversion kit for observation of the starry night sky (0551430) not included!
LUNT LS50C H-alpha double-stack filter for LS50THa
€1,599.00*
Double-stack filter for LS50THa telescopes.The bandwidth of H-alpha systems can be reduced by so-called "double-stacking". A smaller bandwidth provides much more contrast at the solar surface, thereby many more details will become visible.Double-stacking with a bandwidth of only <0.55 Angstrom is also possible at the LS50THa telescopes. Therefore Lunt Solar Systems has especially designed this LS50C double-stack filter in compact housing. The filter threads directly onto the LS50THa telescopes.FEATURESAperture: 50 mmBandwidth: <0.55 AngstromTuning: mechanical tilt-tuningHousing diameter: 85 mmLength: 70 mmWeight: 0.7 kgFront thread: M80x1 female threadRear thread: M80x1 male threadonly usable together with a LS50THa telescope!SCOPE OF DELIVERYLS50C H-alpha double-stack filterInstruction manual
