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 the excellent 2 inch Feather-Touch focuser with 10:1 reduction.
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!
