LUNT LS130MT/DSII doublestack module for LS130MT

The LS130MT/B3400 telescopes can be upgraded with this conversion kit. This allows to explore the Sun at different wavelengths with one and the same telescope, and the telescope can also be used for observing and photographing the starry night sky.You can replace the H-Alpha system of the LS130MT/B3400 telescope with this conversion kit in just a few easy steps. This makes it possible to observe the sun in H-alpha, in the light of the Calcium-K wavelength, or in White-Light - with one and the same telescope!You will only need the additional Ca-K module for LS130MT (item number 0551697), or a LUNT Herschel-wedge (item number 0558201 or 0558211).But there is more: With this conversion kit the LS130MT/B3400 can also be used as a 3-lens apochromatic telescope for astronomical observations and photography at night!This conversion kit turns the LS130MT into a real all-round telescope!This conversion kit was specially designed for the LS130MT/B3400 H-Alpha telescope. Included is a completely new focuser. Simply loosen three knurled screws at the LS130MT/B3400, which hold the H-Alpha unit together with the focuser. Here the new focuser will be fixed, and you have already made your LS130MT a adequate triplet ED apochromatic telescope.This conversion kit can also be used at the LS130MT/B1200 and LS130MT/B1800 telescopes, but it is not necessary there. This conversion kit is only necessary at the LS130MT/B3400, because at this telescope the blocking filter is fix installed inside the focuser.SCOPE OF DELIVERY2" Focuser with 10:1 reduction and adapter to LS130MT telescopeInstruction manualLS130THa telescope not included!

The computer-controlled refractor telescope is a wide-field-lens telescope that goes with you almost anywhere, due to its compact design. Take it with you wherever you go, whether you're hiking, camping or on vacation. Perfect for beginners: the telescope includes an easy-to-use go-to system. The computer-controlled refractor telescope can be operated on a desk or with the included tripod. It will show numerous craters on the moon, the cloud belts on Jupiter and Saturn's rings. These are just the beginning of what can be seen with this telescope. The hand control computer of this telescope solves the beginner's biggest challenge: aligning the telescope with the night sky and finding celestial objects in the vast, starry firmament. The menu navigation of the hand control computer is also multilingual and offers the settings of German, English, French, Spanish and Italian.FEATURESRefractor telescope for beginnersThanks to its compact dimensions also ideal as a travel telescopeComputer control for automatic finding of celestial objectsSCOPE OF DELIVERYRefractor telescope 70/350Aluminium tripod with accessory trayGOTO handcontrolEyepieces (10 and 20 mm)Moon filterRotatable star mapCompas with integrated bubble levelAstronomy software (download)6x Mignon AA batteries are required for operation of the motor - not included!

Modular designed multipurpose telescope, both for observing the sun in the H-alpha wavelength, as well as for night sky observations. Easy conversion between the different applications with a few simple steps. 3-lens apochromatic telescope with FPL-51 glass, 130mm aperture and 910mm focal length - excellent image quality for H-Alpha solar observation and also for observing the starry sky at night. With innovative air pressure tuning system, good 2 inch (50.8mm) R&P focuser, and B3400 blocking filter. Solar observing in H-alpha: The LS130MT/B3400 is a complete telescope for observing the sun in H-alpha light, with 130mm free aperture (no central obstruction) and 910mm focal length. The H-alpha wavelength is the most impressive way to observe the sun, showing protuberances at the sun's edge, filaments and flares on the surface, and much more. An internal Etalon filter achieves a bandwidth of <0.7 Angstrom with the innovative air pressure tuning system Pressure-Tuner. 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 tune to the H-alpha line. The pressure tuner guarantees a homogeneous image, without central obstruction, and a permanently protected Etalon without erosion. A set of collimating lenses installed in the telescope ensures best performance. Fine adjustment is achieved with a solid 2 inch R&P focuser with 10:1 reduction. Blocking-filter is the B3400. The B3400 is good for solar imaging by cameras with very large sensor chips, and can also be used for visual observing. The B3400 blocking-filter is fix installed inside the 2 inch R&P focuser. Observing the starry night sky: The H-Alpha Etalon system can be removed from the telescope in a few easy steps thanks to its modular design. Then the 3-lens apochromatic refractor can be used as a normal telescope with 130mm aperture and 910mm focal length for observation and photography of the night sky. The FPL-51 triplet lens offers an outstandingly low colour aberration image. Common 2 inch star diagonals can be used at the R&P focuser of the telescope. Please note that the optionally available conversion kit 0551696 is absolutely necessary for the LS130MT version with B3400 blocking filter if the telescope is also to be used at night. The conversion kit is not required for the versions with B1200 and B1800. More applications: With additionally available accessories the LS130MT offers even more possibilities! - Double-Stack The LS130MT telescope can optionally be upgraded with the additionally available double-stack module LS130MT/DSII (item number 0551690). The DSII system is a internal double-stack module with Pressure-Tuner. Thereby a bandwidth of <0.5 Angstrom is achieved for H-alpha solar observation. Therefore much more details on the solar surface will become visible. - Solar observing in White-Light If the H-alpha unit has been removed, of course either a sun filter can be installed in front of the objective, or a Herschel-wedge at the focuser can be used to observe the sunspots in White-Light. - Solar observing in Ca-K wavelengthThe additionally available "LUNT Ca-K Filter Module for LS130MT" (item number 0551697) can be used on the LS130MT to observe and photograph super-granulation and other effects visible at this wavelength on the sun. This makes the LS130MT a completely universal usable apochromatic telescope of highest quality!
