multi-purpose telescope of modular design, both for solar observation in the H-alpha wavelength, as well as for the night sky. Easy conversion between different applications with one simple step. 3-lens apochromatic telescope with FPL-53 glass, 100 mm aperture and 714 mm focal length: excellent image quality for H-alpha solar observation and also for observing the starry night sky.

With an innovative air pressure adjustment system, 2-inch (50.8 mm) Feather-Touch focuser and B3400 locking filter.

Solar observation in H-alpha:
The LS100MT/B3400 is a full-featured telescope for observing the sun in H-alpha light, with100 mm free opening(without central obstruction) andfocal length of 714 mm. The H-alpha wavelength is the most impressive way to observe the sun, showing bumps on the edge of the sun, filaments and flares on the surface, and much more. An internal Etalon filter achieves abandwidth of With theinnovative air pressure adjustment systemPressure-Tuner. Tuning is accomplished by slightly modifying the air pressure in a pressure chamber inside the telescope. This changes the refractive index of the air, facilitating tuning to the H-alpha line. The pressure regulator ensures a homogeneous image, without central obstruction, and a permanently protected Etalon without erosion. A collimating lens assembly installed in the telescope guarantees the best performance.
Fine adjustment is achieved with the excellent2-inch Feather-Touch focuser with 10:1 reduction.
Blocking - filter is B3400. The B3400 is good for solar imaging with cameras with a very large sensor chip and can also be used for visual solar observation.
The B3400 locking filter is permanently mounted inside the 2-inch Feather-Touch focuser. Normal 2-inch star diagonals or other 2-inch accessories can be used.

Observation of the starry night sky:
The H-Alpha Etalon system can be removed from the telescope in a few simple steps thanks to its modular design. With the additionally available conversion kit (item number 0551430), the 3-lens ED Apo refractor can be used as a normal telescope with an aperture of 80 mm and a focal length of 560 mm for observation and photography of the night sky. Thetriple target FPL-53Provides an exceptionally low color aberration image. Common 2-inch star diagonals can be used on the high quality R&P focuser from conversion kit 0551430.
Note that the optionally available conversion kit 0551430 is absolutely necessary if the telescope is used at night.

More applications:
With additional accessories available, the LS100MT offers even more possibilities!
-Double stacking
The LS100MT telescope can be optionally upgraded with thedSII/SFPT dual stack moduleAdditionally available (article number 0551395). The DSII system is an internal dual-stack module. This results in a bandwidth of
-Solar observation in white light
If the H-alpha unit has been removed, of course, a solar filter should be placed in front of the objective, or a Herschel wedge should be used in the focuser to observe sunspots in white light.
-Solar observation at Ca-K wavelength
Indeed, Lunt Solar Systems' Ca-K filter modules can also be used in the LS100MT to observe and photograph supergranulation and other visible effects at this wavelength on the sun.

This makes the LS100MT a universal apochromatic telescope of the highest quality
