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/DSII doublestack module for LS130MT
​Double-stack module for more contrast and details on the solar surface at LS130MT telescopes.At the LS130MT H-alpha solar telescopes double-stacking is possible with these internal DSII double-stack modules. The DSII modules reduce the bandwidth to <0.5 Angstroms. The DSII modules are designed to show the surface details of the Sun better, the contrast is significantly increased and thus filaments, active regions and other surface details are much more visible.Like the LS130MT telescope, the DSII Double-Stack module is tuned via the innovative Pressure-Tuner system, and the sensitive Etalon is well protected inside the telescope.The LS130MT/DSII module is designed exclusively for use in the LS130MT telescope, it cannot be used at other telescopes.FEATURESBandwidth: <0.5 AngstromTuning: air-pressure tuning system Weight: 2.3kgSCOPE OF DELIVERYDSII module with internal Etalon for LS130MT telescopesPressure Tuner system(LS130MT telescope not included!)

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! Can only be used together with an LS130MT solar telescope, at LS130MT/B3400 additional conversion kit 0551696 necessary.This Ca-K module is also available for the LS130MT/B3400 as a set together with the required conversion kit (item number 0551695).

LUNT LS2HW 50.8mm (2'') Herschel-wedge
Herschel-wedge / Solar-wedge for superior White-Light solar observing and imaging. For refractor-telescopes up to 150mm aperture, and with 2'' focuser. Complete system with installed ND3.0 filter.Herschel-Wedges will be used to observe the sun in White-Light. Around 95 % of the sun light will be suppressed by the Herschel Wedge. The remaining sun light will be dimmed by a fix installed ND3.0 grey filter. Lunt Solar Systems Herschel-wedges are installed in a fully closed housing with integrated heat trap. There is no stray light escaping, therefore it is very safe.The difference between Herschel-wedges and normal front mounted filters is, that the filtering takes place just before the eyepiece or camera. This will provide a better contrast and sharpness of the solar image.Furthermore, there is more safety at a Herschel-wedge than at a front mounted filter. A Herschel-wedge can not rip or become holes like a foil. And also it can not drop down from the telescope objective accidentally.Only for use with refractor telescopes up to 150mm aperture:Because the full energy and heat of the sun will be inside the telescope, we advise to use only refractors with a Herschel-wedge. The refractor must not have corrector lenses at the back. Optical elements like corrector lenses, or secondary mirrors of reflector telescopes, become very hot by the concentrated solar energy and could be damaged.Tuning the brightness:Because the Herschel-wedge produce polarized light, you can use a normal polarizing filter at the eyepiece or camera-adapter. By turning the polarizing filter the brightness will be reduced.Polarizing filter not included. We recommend the BRESSER 2'' polarizing filter 4946465.FEATURESFor refractor-telescopes up to 150mm apertureConnection to telescope: 2''Connection to eyepiece: 2''90° housing like star-diagonalEspecially high-quality optical surfaces for very good contrastFully closed housing with integrated heat trapNo stray light escaping - therefore it is very safeThe needed ND3.0 filter is fix installedSCOPE OF DELIVERYHerschel-wedge for 2'' focuserIntegrated ND3.0 filterHardcaseInstruction manual

LUNT CAA-RF 0.8x reducer/field-flattener for nighttime photography with LS80MT, LS100MT & LS130MT telescopes
​Field-flattener and focal length reducer for deep-sky astrophotography. Designed for the multipurpose APO telescopes of the Lunt-Solar-Systems LS80MT, LS100MT and LS130MT series.At the telescopes of the MT series from Lunt Solar Systems, the H-Alpha filter unit for solar observation can be removed, then these telescopes can be used as high quality ED APO's for observing and photographing the night sky.This accessory for the LS80MT, LS100MT and LS130MT telescopes shortens the focal length by a factor of 0.8x, providing a larger field of view for deep-sky astrophotography. This also allows shorter exposure times. At the same time, the field of view is flattened for photography.On the camera side, the reducer/field-flattener has a T2 male thread (M42x0.75). DSLR cameras can be connected here directly with a normal T2 ring.For other cameras, an M48x0.75 male thread is available in addition to the T2 male thread. The distance between reducer/field-flattener and camera sensor should be around 50 to 55mm.An M64x1 thread is provided on the telescope side. This allows to connect the reducer/field flattener to the focusers of the conversion kits for the LS80MT, LS100MT and LS130MT telescopes. Please note that for using the reducer/field flattener at the LS80MT, LS100MT or LS130MT telescopes, the corresponding conversion kit for night-time use of the telescope is absolutely necessary..FEATURESShortens focal length of F/7 ED telescopes by a factor of 0.8xFlattened field of view for photographyT2 thread and M48x0.75 thread for camera connectionWorking distance 50 to 55mmSCOPE OF DELIVERY0.8x reducer/field-flattenerAdapter to T2 thread (M42x0.75) and to M48x0.75

LUNT PCUSB Pressure-Tuner Controller with USB
Electronic Control unit with USB connection for one LUNT Pressure-Tuner system.The PC-USB is a microprocessor controlled pressure control system that can be retrofitted to any LUNT instrument (except LS50THa) with Pressure-Tuner (PT), without return to the Lunt facility. A simple air-pipe connects the PC-USB to the Pressure-Tuner. All existing PT systems (except LS50THa) can be retrofitted via an included adapter to the pressure tuner knob. The PC-USB can be used at any altitude.The PC-USB controller can be manually operated directly by the control panel at the housing, or via a computer by USB connection (Windows 7 or higher needed). A USB cable with USB-B plug is necessary for operating by a computer, this USB cable is not included. You will find the software for download on this webpage above at the tab "Manuals".Upon power up the PC-USB will go thru a systems vent and ambient pressure set mode. This will take around 60 seconds. The PC-USB is a simple 2 button system. One button for increasing and one button for decreasing the PT pressure. Digital feedback and indicator lights are provided. The PC-USB is accurate to 0.027 Bar (0.4 PSI), providing very precise control of the pressure setpoint. The PC-USB will auto-compensate for fluctuations in internal pressure changes due to significant changes in temperature. The PC-USB can be user programmed to center wavelength set point. Due to the sealed nature of the system, the center wavelength set point will remain constant at any altitude at a given set pressure point. Because the PC-USB can provide closed-loop feedback of internal etalon pressure users can correlate change in pressure to doppler shifted events.Normally the telescope shakes while you are tuning mechanically. Especially if you use high magnification, for example for observing the Doppler effect at a filament. With the PC-USB system there will be absolutely no shaking of the telescope while tuning at all magnifications, so observing Doppler shifted events will become more comfortable.The PC-USB can run continuously on internal battery power for more than 8 hours. It has external power input (15V DC) that can power the unit and charge the internal batteries simultaneously.SCOPE OF DELIVERYLUNT PC-USB Control SystemAdapter for PT knob3m air-pipeAC-adapter (with Euro-plug)Please note that this controller is not compatible with LS50THa series telescopes!
