Modular designed multipurpose telescope, both for observing the sun in the H-alpha wavelength, as well as for night sky observations. Easy conversion between the different applications with a few simple steps. Excellent image quality due to 2-lens ED optics with 70mm aperture for night sky observation, and 60mm usable aperture for H-alpha solar observation.

With innovative air pressure tuning system, high-end 2 inch (50.8mm) Feather-Touch focuser, and B600 blocking filter.

Solar observing in H-alpha

The Lunt LS60MT/B600 is a complete telescope for observing the sun in H-alpha light, with 60mm free aperture (no central obstruction) and 420mm 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 outstanding 2 inch Feather-Touch focuser from Starlight-Instruments with 10:1 reduction.
Blocking-filter is the B600. The B600 is good for visual solar observing. Also solar imaging is possible by cameras with small CCD chip. We recommend a Lunt LS60MT with B1200 blocking-filter by using cameras with middle or large sized CCD 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. The 2-lens ED refractor can then be used as a normal telescope with 70mm aperture and 420mm focal length for observation and photography of the night sky. The ED Doublet lens will offer an excellent image. It can be used with a standard 2 inch zenith mirror at the Feather-Touch focuser.
With an additional Amici prism, the telescope can of course also be used during the day for nature and landscape observations.
This makes the Lunt LS60MT, with its small dimensions and low weight, also an ideal travel telescope for all applications!

More applications

With additionally available accessories the Lunt LS60MT offers even more possibilities!

Double-Stack/strong>

The Lunt LS60MT telescope can optionally be upgraded with the additionally available double-stack filters Lunt LS50FHa or Lunt LS60FHa (part numbers 0550200 and 0550250). These filters will be simply screwed on the front of the Lunt LS60MT, no additional adapters are necessary. 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 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 Lunt LS60MT to observe and photograph super-granulation and other effects visible in this wavelength on the sun.

This makes the Lunt LS60MT a completely universal usable telescope!
