The LS80MT/B1200 is a complete telescope for observing the sun in H-alpha light, with 80mm free aperture (no central obstruction) and 560mm 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 less than 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 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 LS80MT with B1800 blocking-filter by using cameras with large sized sensor chips.
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 LS80MTBP&F the 2-lens ED Apo refractor can then be used as a normal telescope with 80mm aperture and 560mm focal length for observation and photography of the night sky. The FPL-53 doublet lens offers an low colour aberration image. Common 2 inch star diagonals can be used at the high quality R&P focuser of the conversion kit LS80MTBP&F.
Please note that the optionally available conversion kit is absolutely necessary if the telescope should be used at night. More applications:
With additionally available accessories the LS80MT offers even more possibilities!

- Double-Stack
The LS80MT telescope can optionally be upgraded with the additionally available double-stack module DSII/SFPT. The DSII system is an internal double-stack module. Thereby a bandwidth of less then 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 LS80MT to observe and photograph super-granulation and other effects visible in this wavelength on the sun.

This makes the LS80MT a completely universal usable ED Apo telescope of very good quality!
