• 3-lens ED refractor FPL-51, aperture 130 mm, focal length 910 mm
• Observation and photography with excellent image quality
• Bandwidth less than 0.7 Angstrom
• Large B3400 blocking filter installed inside the focuser
• Robust R&P focuser with 10:1 reduction
• Also for Ca-K solar observation and white light
• Absolutely safe, no danger to eyes

Multi-purposetelescopeof modular design for both H-alpha wavelength solar observation and night sky observations. Easy conversion between different applications with a few simple steps. 3-lens apochromatic telescope with FPL-51 glass, 130 mm aperture and 910 mm focal length: excellent image quality for solar observation in the H-alpha wavelength and also for starry night sky observation.

With innovative air pressure tuning system, good 2-inch (50.8 mm) R&P focuser and B3400 blocking filter.

H-alpha solar observation:

The LS130MT/B3400 is a complete telescope for sun observing in H-alpha light, with 130mm free aperture (no central obstruction) and 910mm focal length. 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 a bandwidth of

Fine tuning is achieved with a solid 2-inch R&P focuser with 10:1 reduction.

The blocking filter is the B3400. The B3400 is suitable for solar imaging using cameras with very large sensor chips, and can also be used for visual observation.

The B3400 blocking filter is permanently mounted inside the 2-inch R&P focuser.

Observing the starry night sky:

The H-Alpha Etalon system can be removed from the telescope in just a few steps thanks to its modular design. The 3-lens apochromatic refractor can then be used as a normal telescope with an aperture of 130 mm and a focal length of 910 mm for night sky observation and photography. The FPL-53 triple objective lens provides an image with extraordinarily low chromatic aberration. Common 2-inch star diagonals can be used on the telescope's R&P focuser.

Note that the optionally available conversion kit 0551696 is absolutely necessary for the LS130MT version with B3400 blocking filter if the telescope is also to be used at night. The conversion kit is not required for versions with B1200 and B1800.

More applications:

With the additionally available accessories, the LS130MT offers even more possibilities.

- Double stack

The LS130MT telescope can be optionally upgraded with the LS130MT/DSII double stack module (article number 0551690). The DSII system is an internal double stack module with pressure tuner. This achieves a bandwidth of

- Solar observation in white light

If the H-alpha unit has been removed, a solar filter can be installed in front of the objective or a Herschel wedge can be used in the focuser to observe sunspots in white light.

- Solar observation at Ca-K wavelength

The additionally available "LUNT Ca-K filter module for LS130MT" (item number 0551697) can be used on the LS130MT to observe and photograph supergranulation and other visible effects at this wavelength on the sun.

This makes the LS130MT a universally usable apochromatic telescope of the highest quality.
