About this product

Model:  lunt_ls800mt__c
Part Number:  0551320

IMPORTANT: This telescope is supplied without the blocking filter (diagonal) shown in product photos. Do not use this telescope to observe the Sun without a suitable Lunt blocking filter! 

This highly versatile modular telescope can be combined with a LUNT blocking-filter to safely observing the Sun in H-alpha, Ca-K or White-Light. 

Lunt offer a range of optional blocking filters in different sizes, either mounted in a 90° star-diagonal housing or in a straight extension tube.

  • Length without blocking filter and removed dew-shield: 50cm

Solar observing in H-alpha:

The LS80MT is a telescope for observing the sun in H-alpha light, with 80mm free aperture (no central obstruction) and 560mm 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 2 inch Crayford focuser with 10:1 reduction.

This version of the LS80MT 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. An optional Lunt conversion kit with R&P focuser (item number 0551330) is available that enables you to fit a regular 2" Star Diagonal for night-time visual astronomy and astrophotography. When used this way the telescope's unobstructed 80mm ED doublet optics provide clear views with high contrast and minimal chromatic aberration. 

More applications:

With additionally available accessories the LS80MT offers even more possibilities!

Double-Stack

The LS80MT telescope can optionally be upgraded with the additionally available double-stack module DSII/SFPT (item number 0551395). The DSII system is a internal double-stack module. 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 LS80MT to observe and photograph super-granulation and other effects visible in this wavelength on the sun.
