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 and good 2 inch (50.8mm) R&P focuser. Delivered without blocking filter, use for H-Alpha sun observation only possible with additional blocking filter!

This telescope is supplied without blocking filter. We offer a wide range of additionally available blocking filters in different sizes, either mounted in a 90° star-diagonal housing or in a straight extension tube. These are all usable with this telescope.

ATTENTION: Without such an additional blocking filter you cannot use this telescope for H-alpha solar observation!

Solar observing in H-alpha:

The LS100MT is a telescope for observing the sun in H-alpha light, with 100mm free aperture (no central obstruction) and 714mm 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 .

This version of the LS100MT is delivered without blocking filter. Therefore an additional blocking filter is required to use the telescope for solar observation in the H-alpha wavelength. You can choose from the wide range of Lunt Solar Systems blocking filters and decide for example if you want a blocking filter in a 90° star-diagonal housing or one in a straight extension tube.

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!
