The LUNT LS60MT/R&P Multipurpose Telescope OTA is a versatile instrument designed for both solar observation in H-alpha light and night sky viewing. It features a modular design that allows for easy conversion between solar and astronomical uses. For solar observation, a LUNT blocking filter is necessary, and the telescope offers impressive capabilities with a 60mm aperture and a 420mm focal length. The H-alpha wavelength observation reveals detailed solar phenomena such as prominences, filaments, and flares.
Key features include a 2-lens ED refractor with an FPL-51 glass offering a 70mm aperture for night sky observation and 60mm for H-alpha solar observation, promising excellent image quality. The telescope is equipped with a high-quality 2-inch Rack & Pinion (R&P) focuser with a 10:1 reduction for fine adjustments. Its air pressure tuning system, known as Pressure-Tuner, allows precise tuning to the H-alpha line by adjusting the air pressure in a chamber inside the telescope, ensuring a homogeneous image without central obstruction.
For solar observation, the internal Etalon filter achieves a bandwidth of less than 0.7 Angstrom, and the system's modular design means the H-alpha Etalon can be removed for night-time astronomical observation, utilizing the full 70mm aperture. The LS60MT is designed to be safe for observing the sun when equipped with the necessary blocking filter, and it also allows for additional observational capabilities such as double-stacking with optional filters for enhanced solar detail, white-light observing with a sun filter or Herschel-wedge, and Ca-K wavelength observation for super-granulation effects.
The LS60MT's portability and modular design make it an ideal choice for enthusiasts who demand flexibility and high-quality performance in their observations, whether tracking solar activity or exploring the night sky. Its adaptability, combined with the quality of its optical and mechanical components, positions it as a highly regarded telescope in the astronomy community
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 and high-quality 2 inch (50.8mm) Rack&Pinion (R&P) focuser. Delivered without blocking filter, use for H-Alpha sun observation only possible with additional blocking filter!
This telescope is supplied without blocking filter. We offer a wide range of additionally available blocking filters in different sizes, either mounted in a 90° star-diagonal housing or in a straight extension tube. These are all usable with this telescope.
ATTENTION: Without such an additional blocking filter you cannot use this telescope for H-alpha solar observation!
Solar observing in H-alpha:
The LS60MT is a 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 solid 2 inch Rack&Pinion focuser with 10:1 reduction.
This version of the LS60MT is delivered without blocking filter. Therefore an additional blocking filter is required to use the telescope for solar observation in the H-alpha wavelength. You can choose from the wide range of Lunt Solar Systems blocking filters and decide for example if you want a blocking filter in a 90° star-diagonal housing or one in a straight extension tube.
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 or other accessories at the R&P focuser, the back focus is 135mm.
With an additional Amici prism, the telescope can of course also be used during the day for nature and landscape observations.
This makes the LS60MT, with its small dimensions and low weight, also an ideal travel telescope for all applications!
More applications:
With additionally available accessories the LS60MT offers even more possibilities!
- Double-Stack
The LS60MT telescope can optionally be upgraded with the additionally available double-stack filters LS50FHa or LS60FHa (part numbers 0550200 and 0550250). These filters will be simply screwed on the front of the 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 LS60MT to observe and photograph super-granulation and other effects visible in this wavelength on the sun.
This makes the LS60MT a completely universal usable telescope!
