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.

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

Calcium-K module in straight extension tube, for using normal astronomical telescopes up to 100mm aperture and up to 1080mm focal length as Ca-K solar telescopes.This Calcium-K module transforms your normal astronomical refractor telescope into a Ca-K solar telescope. It will be very easy: Put the Ca-K module into the 2" focuser of your telescope, and you are ready for solar observing in the light of the Calcium-K wavelength.Internal narrowband filters allow for a <2.4 Angstrom bandwidth. For refractor telescopes up to 100mm aperture and up to 1080mm focal length. For imaging it will be better to use a bigger Ca-K module.The Ca-K module is in a straight extension tube, for 2" focuser on the telescope side, and with T2 thread and 1.25" eyepiece connection on the eyepiece side.All needed filter parts are integrated inside the compact module. There are no additional filters needed.The Ca-K wavelength is at the edge of the visible light spectrum for human eyes, so for many people visual observing is difficult. However, all details could be captured photographically. Therefore the Ca-K Module is optimized primarily for imaging.FEATURESBandwidth <2.4 AngstromUsable at telescopes up to 100mm aperture and 1080mm focalStraight extension tube housing2" slide tube for 2" focuserConnection for 1.25" eyepiecesT2 thread for camera connectionSCOPE OF DELIVERYCa-K module in straight extension tube for 2" focuserIntegrated blocking filter B1200 for telescopes up to 1080mm focal lengthInstruction manual
