LUNT LS100MT/B1200R&P Multipurpose APO Telescope for Sun + Night-Sky

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-53 glass, 100mm aperture and 714mm 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 B1200 blocking filter. Solar observing in H-alpha: The LS100MT/B1200 is a complete telescope for observing the sun in H-alpha light, with 100mm free aperture (no central obstruction) and 714 mm 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 B1200. The B1200 is good for visual solar observing. Also solar imaging is possible by cameras with small sensor chip. We recommend a LS100MT with B1800 blocking-filter by using cameras with middle or large sized sensor chips, at very large sensor chips the B3400 blocking-filter. The star diagonal in which the blocking filter is installed, is equipped as standard for 1.25 inch eyepieces and with a T2 camera connection. 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. With the additionally available conversion kit (item number 0551430) the 3-lens apochromatic refractor can then be used as a normal telescope with 100mm aperture and 714mm focal length for observation and photography of the night sky. The FPL-53 triplet lens offers an outstandingly low colour aberration image. Common 2 inch star diagonals can be used at the high quality R&P focuser of the conversion kit 0551430. Please note that the optionally available conversion kit 0551430 is absolutely necessary if the telescope should be used at night. More applications: With additionally available accessories the LS100MT offers even more possibilities! - Double-Stack The LS100MT telescope can optionally be upgraded with the additionally available double-stack module DSII/SFPT (item number 0551395). The DSII system is a internal double-stack module. 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 to 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 wavelength Certainly, the Ca-K filter modules from Lunt Solar Systems can also be used at the LS100MT to observe and photograph super-granulation and other effects visible in this wavelength on the sun. This makes the LS100MT a completely universal usable apochromatic telescope of highest quality!

LUNT HRG/SFPT anti-reflection filter for DSII/SFPT double-stack at LS80MT & LS100MT telescopes

The anti-reflection filter is an accessory for the DSII/SFPT double-stack module for the Lunt Solar Systems LS80MT and LS100MT telescopes. Reflections that may occur there can be effectively reduced with this anti-reflection filter if necessary.At the LS80MT and LS100MT multipurpose telescopes from Lunt Solar Systems, double-stacking is possible in H-alpha mode for solar observation with the internal DSII/SFPT double-stack modules (item number 0551395). The DSII modules reduce the bandwidth to <0.5 Angstroms. The DSII modules are designed to show better the surface details of the Sun, the contrast is significantly increased, and therefore filaments and active areas are better visible.But the DSII modules can also induce reflections, which can show up as a strong brightening around the sun. This so-called ''glow'' is not a problem when observing the solar surface. But it can complicate the observation of prominences, and many observers find it disturbing. The HRG/SFPT anti-reflection filter is designed to solve this problem. The filter effectively reduces the reflections. But please also note that the image will become darker by using this anti-reflective filter.The HRG/SFPT anti-reflection filter is easy to install. It is not necessary to return the telescope to the manufacturer, the filter can be easily installed by the user.This filter cannot be used separately! It can only be used on a Lunt Solar Systems LS80MT or LS100MT telescope together with a DSII/SFPT Double-Stack module.SCOPE OF DELIVERYHRG/SFPT anti-reflection filterInstruction manual
