Product information "LUNT LS130MT/B1800 Multipurpose APO Telescope for Sun + Night-Sky"

Complete H-alpha Solar Telescope with 130mm aperture and <0.7 Angstrom bandwidth. With Feather-Touch focuser, advanced air-pressure tuning system, and B1800 Blocking Filter.

The LS130MT is a triplet ED apochromatic refractor with modular design! The telescope can also be used for night sky observations, and with the optional available accessories also for observing the sun in the Ca-K wavelength and in White-Light!

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 higher resolution compared to telescopes with smaller aperture allows the observer to dive into the fine details and surface phenomena of our ever-changing Sun. The higher resolution allows higher magnifications, bringing the fine details of the Sun to life in the eyepiece or on the screen.
An internal Etalon filter with the innovative air pressure tuning system Pressure Tuner achieves a bandwidth of <0.7 Angstroms. The 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 adjust to the H-alpha line. The pressure tuner guarantees an homogeneous image without central obstruction and a permanently protected etalon without wear. A set of collimating lenses installed in the telescope ensures best performance.
Fine adjustment is achieved by a 2" Starlight-Instruments Feather-Touch focuser with 1.5" travel and 10:1 reduction.

Blocking-filter is the B1800. The B1800 is good for visual solar observing and also for solar imaging by cameras with small to large CCD chip. We recommend a LS130MT with B3400 blocking-filter by using cameras with very large sized CCD chips.
The star diagonal in which the blocking filter is installed, is equipped as standard for 1.25" eyepieces and with a T2 camera connection.

Also the LS130MT telescope is upgradeable with the additional available DSII double-stack system (item no. 0551690). The optional DSII system is a internal double stack module with Pressure Tuner, that provides a bandwidth <0.5 Angstrom. More details on the solar surface will become visible by reducing the bandwidth.

Modular design:
The H-Alpha Etalon system can be easily removed from the telescope. The 3-lens ED Apochromat can be used as a normal telescope for observation and imaging of the night sky.
Also available is a Ca-K module (item number 0551697) specially developed for the LS130MT. This also allows to observe the sun in the blue calcium wavelength.
A Herschel-wedge (item number 0558201) can also be used for observing the sun in white light.
This makes the LS130MT 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 Ca-K filter-module for LS130MT

This Ca-K module can be used at the LS130MT/B1200 and LS130MT/B1800 telescopes to observe the Sun also in the Calcium-K line. At the LS130MT/B3400 additionally the conversion kit for the LS130MT is required (item number 0551696).You can use this Ca-K module with your LS130MT telescope to observe and photograph the Sun not only in H-alpha, but also in the blue calcium-K wavelength. Here again completely different phenomena become visible on the Sun than in H-alpha.This Ca-K module was specially designed for the LS130MT H-Alpha telescope. If the H-alpha Etalon unit is removed from the LS130MT, the Ca-K module is simply inserted into the focuser instead of the blocking-filter.The additional conversion kit 0551696 is necessary at the LS130MT/B3400, because at this telescope the blocking filter is fix installed inside the focuser.For human eyes, the calcium-K light is just at the limit of the visible range. Many people have problems with visual observation. However, this does not apply to photography, where the Ca-K module shows everything the Sun has to offer in this wavelength.SCOPE OF DELIVERY2'' Ca-K Module for LS130MT telescopeInstruction manualLS130MT telescope and conversion kit not included!

LUNT Sol Searcher

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

EXPLORE SCIENTIFIC 82° Ar Eyepiece 14mm (1,25")

Explore Scientific 82° Series™ extreme wide field eyepieces are optimized to produce high contrast, high resolution, and superior flat field characteristics. The visual effect of these eyepieces with their long eye-relief and their 82° apparent field is truly a full-immersion experience. Your eye is relaxed, allowing you to easily use the "averted vision" technique to study faint details across a huge field-of-view. The 82° Series eyepieces come with a twist-up rubber eye-guard that raise to the desired height for the comfort of the observer, and as experienced astronomers know, eye comfort is critical when trying to observe at the visual limits of the telescope. To keep internal reflections to a minimum, all internal surfaces of the eyepiece barrel are flat black, as well as the edges of the lenses themselves to minimize the scattering of light within the lenses themselves. All 82° Series eyepieces are fully multi-coated and edge-blackened to produce maximum contrast.

EXPLORE SCIENTIFIC 100° Ar Eyepiece 20mm (2")

These eyepieces with their huge apparent field of view not only gave the observer a panoramic visual experience, but they relax the eye so the observer could pay attention to subtle details for extended periods. These ultra-wide angle eyepieces played a critical role in the military for aiming at targets, and their long eye-relief counterparts helped reduce eye injury from recoil. Each 100° Series Nitrogen-Purged Waterproof eyepiece is internally sealed and purged with inert, dry nitrogen gas to prevent internal fogging, to halt the intrusion of fine particulates and fungus, and to maximize the life of the internal coatings. To make sure, every 100° eyepiece is tested by submerging them down to 1 meter of water for 30 minutes. All 100° Series eyepieces are fully multi-coated and edge-blackened to produce maximum contrast.
