Product information "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.

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 LS130MT/B1200 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 B1200 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/B1200 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 B1200. The B1200 is good for visual solar observing. Also solar imaging is possible by cameras with small CCD chip. We recommend a LS130MT with B1800 blocking-filter by using cameras with middle or large sized CCD chips, at very large CCD chips the B3400 blocking-filter.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!FEATURESTriplet ED apochromatic refractor, FPL-51Aperture: 130mm (no central obstruction)Focal length: 910mmBandwidth: internal Etalon with <0.7 AngstromTuning: air-pressure tuning systemBlocking-filter: B1200 with 1.25" and T2 connectionFocuser: Starlight-Instruments Feather-Touch focuser with 10:1 reductionTwo tube rings with carrying handleDove tail bar with GP level for astronomical MountsWeight: 12.1kgLength with blocking-filter and dew-shield: 100cmLength without blocking-filter and removed dew-shield: 80cmSCOPE OF DELIVERYLS130MT multipurpose telescopePressure-Tuner systemB1200 blocking-filter in star-diagonal2" Feather-Touch focuserTube-extension for using without H-alpha EtalonTube rings with dove tail barTransport case (92x42x35cm)Instruction manual
