Product Highlights
Modular 130mm ED Apo telescope for observing & photographing prominences & more at the sun during the day and moon, planets & deep-sky at night
- Special telescope for observing the Sun in H-alpha
- Also for night sky observing, modular design
- 3-lens ED refractor FPL-51, 130mm aperture, 910mm focal length
- Observation & photography with excellent image quality
- Bandwidth less than 0.7 Angstrom
- Very large B3400 blocking filter installed inside focuser
- Solid R&P focuser with 10:1 reduction
- Also for Ca-K & White-Light solar observing
- Absolutely safe, no danger to the eyes
With innovative air pressure tuning system, good 2 inch (50.8mm) R&P focuser, and B3400 blocking filter.
Solar observing in H-alpha:
The LS130MT/B3400 is a complete telescope for observing the sun 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 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.
Blocking-filter is the B3400. The B3400 is good for solar imaging by cameras with very large sensor chips, and can also be used for visual observing.
The B3400 blocking-filter is fix installed inside the 2 inch R&P focuser.
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. Then the 3-lens apochromatic refractor can be used as a normal telescope with 130mm aperture and 910mm focal length for observation and photography of the night sky. The FPL-51 triplet lens offers an outstandingly low colour aberration image. Common 2 inch star diagonals can be used at the R&P focuser of the telescope.
Please 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 the versions with B1200 and B1800.
More applications:
With additionally available accessories the LS130MT offers even more possibilities!
- Double-Stack
The LS130MT telescope can optionally be upgraded with the additionally available double-stack module LS130MT/DSII (item number 0551690). The DSII system is a internal double-stack module with Pressure-Tuner. 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 can 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
The additionally available "LUNT Ca-K Filter Module for LS130MT" (item number 0551697) can be used on the LS130MT to observe and photograph super-granulation and other effects visible at this wavelength on the sun.
This makes the LS130MT a completely universal usable apochromatic telescope of highest quality!
