Product information "LUNT LS18CaKMDs2 Ca-K filter in extension tube"
Calcium-K module in straight extension tube, for using normal astronomical telescopes up to 100mm aperture and up to 1620mm 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 1620mm 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.

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 Solar Systems zoom-eyepiece with variable focal length from 7.2mm to 21.5mm, with 1.25 inch (31.7mm) connection.The special of this zoom eyepiece is that the optical layout offers highest quality views of the sun, but also on nightsky objects. LUNT minimized the reflections by using superb multicoatings and with care designed internal baffle system and blackened lens edges. The LUNT zoom-eyepiece is not the widest field zoom-eyepiece on the market, LUNT prefered best performance over widest field. The sun and stars are perfect pin point across the entire field of view without any visible distortion. The LUNT zoom-eyepiece is almost parfocal, from one end to the other end of the zooming way you need only 0.5mm to refocuse. The LUNT zoom-eyepiece has a very nice height adjustable eyeguard to protect your eye against day light reflections and to help you to find the perfect eye position.Please note that these eyepieces are only accessories for existing solar telescopes or filters when observing the sun.

VMC 260L Maksutov Cassegrain AXD Version
The optics of the VMC260L surpass the traditional Schmidt-Cassegrain and this tube is only 650 mm in length, despite its long focal length of 3000 mm . With its large aperture of 260 mm , the telescope collects light for serious professional observations and photography of the planets, as well as countless deep-sky objects. The dielectrically coated mirrors of the VMV260L guarantee high sharpness and maximum brightness. Thanks to the open tube, this instrument cools down faster than conventional closed Cassegrain systems, and (having no front corrector plate) is not as prone to dewing issues either.An optional 0.62x focal reducer is available for expansion to reduce the focal ratio to 1: 7.1. This results in a shortening of the exposure times and the increasing the field of view, thus increasing the ability to photograph larger objects in the sky. Included accessories feature a finder, dovetail rail and a handle that assists considerably when mounting and de-mounting the scope and can also be used as a camera holder for star field recordings.CHARACTERISTICSAperture: 260 mm precision spherical mirror, multi-coatedLight gathering power: 1380xAdapter and connections: 60 mm on the focuser; 42 mm for T-mount and 31.7 mm with folding mirror; 50.8mm optionPhotography: primary focus and eyepiece projectionWHAT'S INCLUDEDVMC260L reflectorDovetail rail (3 inch for AXD)AXD SaddleplateCarrying handleFinderscope 7x50Flip mirror

LUNT LS40FHa H-alpha double-stack filter for LS40THa
Double-stack filter for LS40THa telescopes. The bandwidth of H-alpha systems can be reduced by so-called "double-stacking". A smaller bandwidth provides much more contrast at the solar surface, thereby many more details will become visible. Double-stacking with a bandwidth of only <0.55 Angstrom is also possible at the LS40THa telescopes. Therefore Lunt Solar Systems has especially designed this LS40FHa double-stack filter in compact housing. FEATURES Aperture: 40 mm Bandwidth: <0.55 Angstrom Tuning: mechanical tilt-tuning Housing diameter: 70mm Length: 60mm Weight: 0,3kg only usable together with a LS40THa telescope!
