The LS100MT is a complete telescope for observing the Sun in H-alpha light, with a 100mm clear aperture (no central obstruction) and 714mm focal length. The H-alpha wavelength is the most impressive way of viewing the Sun - it makes solar prominence at the edge of the Sun, filaments and flares on the surface and much more visible. An internal Etalon filter, with its innovative air pressure tuning system, reaches a half width of <0.7 angstrom.
Night sky watching:Thanks to its modular construction, the solar filter can be removed from the telescope with just a few flicks of the wrist. With an optional conversion kit (see “Recommended Accessories”), the 3-lens apochromatic refracting telescope can be used as a telescope for observing and photographing the night sky. The triplet lens with special FPL-53 glass provides a pure-colour image for this. Standard 2-inch zenith mirrors can be used on the conversion kit’s very high-quality R&P focuser. This optional conversion kit is essential for using the telescope at night.
The connection between eyepiece and camera: The block filter is built into the deflection optics which is compulsory for solar observation! This filter takes eyepieces or cameras with 1.25” sockets, but also has a T2 thread. The blocking filter is not required for nocturnal observation. The focuser can hold the zenith mirror or other accessories with 2” sockets.
PT pressure tuner: Fine-tuning on the Etalon filter is provided via an air pressure system. A small change to air pressure within a pressure chamber inside the telescope changes the refractive index of the air, resulting in precise yet effortless adjustment to the H-alpha spectral line. The pressure tuner guarantees a uniform image with no central obstructions and a long-lasting wear-resistant etalon.
The B1200 blocking filter is well-suited to visual solar observation. Solar photography is also possible with cameras which have a small sensor chip, namely typical planetary cameras. For cameras with medium-sized or large sensors, a telescope with a larger blocking filter should be used so that the sensor will be well illuminated.
