About this product

Model:  lunt_ls30mt_b3400
Part Number:  0551603

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
  • For Sun photography & visual observation
  • Bandwidth less than 0.7 Angstrom
  • Modular design
  • Also for Ca-K & White-Light solar observing
  • Also for night sky observing
  • Triplet ED APO refractor FPL-51
  • Very large B3400 blocking filter in extension-tube

Complete H-alpha Solar Telescope with 130mm aperture and <0.7 Angstrom bandwidth. With Feather-Touch focuser, advanced air-pressure tuning system, and B3400 Blocking Filter.

The LS130MT is a triplet ED apochromatic refractor with modular design! With the optional accessories, the telescope can also be used for night sky observations, as well as for observing the sun in the Ca-K wavelength and in White-Light!

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 higher resolution compared to telescopes with smaller aperture allows the observer to dive into the fine details and surface phenomena of our ever-changing Sun. The higher resolution allows higher magnifications, bringing the fine details of the Sun to life in the eyepiece or on the screen.
An internal Etalon filter with the innovative air pressure tuning System Pressure Tuner achieves a bandwidth of <0.7 Angstroms. The 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 adjust to the H-alpha line. The pressure tuner guarantees an homogeneous image without central obstruction and a permanently protected etalon without wear. A set of collimating lenses installed in the telescope ensures best performance.
Fine adjustment is achieved by a 2" Starlight-Instruments Feather-Touch focuser with 1.5" travel and 10:1 reduction.

Blocking-filter is the B3400. The B3400 is good for solar imaging by cameras with very large CCD chip and can also be used for visual solar observing.
The B3400 blocking filter is fix installed inside the 2" Feather-Touch focuser.

Also the LS130MT telescope is upgradeable with the additional available DSII double-stack system (item no. 0551690). The optional DSII system is a internal double stack module with Pressure Tuner, that provides a bandwidth <0.5 Angstrom. More details on the solar surface will become visible by reducing the bandwidth.

Modular design:
The H-Alpha Etalon system can be easily removed from the telescope. With the additionally available conversion kit (item number 0551696) the 3-lens ED Apochromat can be used as a normal telescope for observation and imaging of the night sky.
Also available is a Ca-K module (item number 0551697) specially developed for the LS130MT, also available as a complete set with the conversion kit (item number 0551695). This also allows to observe the sun in the blue calcium wavelength.
A Herschel-wedge (item number 0558201) can also be used at the conversion kit for observing the sun in white light.
This makes the LS130MT a completely universal usable telescope!
