Product information "LUNT LS60MT/R&P Multipurpose Telescope OTA without Blocking Filter"
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 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-Stack
The 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-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 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!

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 Sol Searcher
€59.00*
Sol-Searcher for installing on all solar telescopes of Lunt Solar Systems. The tube rings of the LUNT solar telescopes are prepared for the mounting of this Sol-Searcher."I can't find the Sun!" sounds funny. However, the Sun is tricky to find in a properly filtered telescope, and you don't ever want to chance a direct gaze, let alone a magnified image of it.This Sol-Searcher is the safe and easy way to find the Sun. It is absolutely safe since you don't look through Sol-Searcher, you look at it. The aperture acts as a "pinhole" which projects an image of the Sun on to the 1/4" translucent "screen." This screen can be viewed from either side. Simply move your scope until the Sun's image is centered on the screen and the Sun will be in the eyepiece's field of view.The solar telescopes from Lunt Solar Systems are fitted for installing this Sol-Searcher. Only at the LS130MT and LS152THa telescopes the additionally adapter 0554302 will be needed.SCOPE OF DELIVERYTeleVue Sol-SearcherScrewsHexagon wrench

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

observation.With innovative air pressure tuning system, high-quality 2 inch (50.8mm) Rack&Pinion (R&P) focuser, and B1200 blocking filter.Solar observing in H-alpha:The LS60MT/B1200 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 B1200. The B1200 is very good for visual solar observing, and also for solar imaging.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: B1200 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-TunerB1200 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

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.FEATURESAperture: 40mm (no central obstruction, 2-lens refractor)Focal length: 400mmBandwidth: <0.7 AngstromTuning: mechanical tilt-tuningBlocking filter: B1200 with 1.25 inch connectionFocuser: Helical focuserDovetail bar at standard GP-level1/4-20 tapped base (standard thread for photo-tripods)Sol-Searcher includedWeight: 1.2kgLength: 41cmSCOPE OF DELIVERYLS40THa Solar TelescopeB1200 blocking filter in star-diagonal housing1.25 inch Helical focuserDovetail bar (GP level)Sol-SearcherInstruction manual
