Absolutely safe, no danger to eyesight
Multi-purpose telescope of modular design: H-alpha wavelength solar and night sky observation. Easy to switch from one application to another in a few simple steps. 2-lens ED Apo telescope with FPL-53 glass, 80 mm aperture and 560 mm focal length - very good image quality for H-alpha solar observation and also for starry night sky viewing.
Includes an innovative air pressure adjustment system and a good 2 inch (50.8 mm) R&P focuser. Supplied without blocking filter, note: use for H-Alpha solar observation is only possible with an additional blocking filter
This telescope is supplied without a blocking filter. We offer a wide range of additionally available blocking filters in different sizes, mounted on a 90° diagonal star or on an extension tube. All are usable with this telescope.
ATTENTION: You cannot use this telescope for H-alpha solar observing without this additional blocking filter !
H-alpha solar observing:
The LS80MT is a telescope for sun observation in H-alpha light, with 80 mm free aperture (no central obstruction) and 560 mm focal length. The H-alpha wavelength is the most impressive way to observe the sun, showing bumps on the edge of the sun, filaments and flares on the surface and much more. Its internal Etalon filter achieves a bandwidth of
It achieves fine tuning with a solid 2-inch R&P focuser with 10:1 reduction.
This version of the LS80MT is delivered without a blocking filter. Therefore, for solar observation in the H-alpha wavelength an additional blocking filter is required in this telescope . You can choose from the wide range of Lunt Solar Systems blocking filters and decide, for example, whether you want a 90° diagonal star blocking filter or one in an extension tube.
Observe the starry night sky:
With its modular design, you can remove the H-Alpha Etalon system in a few simple steps. With the additionally available conversion kit (item number 0551330), the 2-lens ED Apo refractor can be used as a normal telescope with an aperture of 80 mm and a focal length of 560 mm for observation and photography of the night sky. The FPL-53 double objective lens provides an image with low chromatic aberration. Normal 2-inch star diagonals can be used on the high quality R&P focuser in conversion kit 0551330.
Note that the optionally available 0551330 conversion kit 0551330 is absolutely necessary if you want to use the telescope at night.
More applications:
With the additional accessories available, the LS80MT offers even more possibilities
- Double-Stack (Double-Stack)
The LS80MT telescope can be optionally upgraded with the DSII/SFPT double-stack module also available (article number 0551395). The DSII system is an internal double-stack module. It thus achieves a bandwidth of
- Solar observation in white light:
To observe sunspots in white light, s you have removed the H-alpha unit, you must place a solar filter in front of the objective, or use a Herschel wedge on the focuser .
- Solar observation at Ca-K wavelength
Of course, the Lunt Solar Systems Ca-K filter modules can also be used on the LS80MT to observe and photograph supergranulation and other visible effects at this wavelength on the sun.
