The Lunt LS100MT is a telescope designed for observation of the Sun in H-Alpha light. The H-Alpha wavelength offers the most impressive way to observe the Sun, revealing prominences at the solar limb, filaments and flares on the surface, and much more.
An internal Etalon filter, combined with the innovativetuning system, achieves a half-width at half-maximum of less than 0.65 angstroms. A set of collimating lenses installed in the telescope ensures optimum performance.
Focusing is achieved via a sturdy 2-inch R&P focuser with a 1:10 reduction ratio.
Night-time sky observation: The H-alpha Etalon system can be removed from the telescope in just a few simple steps. The 3-lens apochromatic refractor can then be used as a standard telescope for observation and photography of the night sky.
But this also expands the possibilities for solar observation: without the h-alpha filters, the telescope can be fitted with a white light filter or a Herschel prism to observe sunspots.
The FPL-53 triplet objective delivers an outstanding, colour-pure image. Standard 2-inch diagonal mirrors can be used with the high-quality R&P focuser.
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 B1800 blocking filter is very well suited to visual solar observation but can also be utilised for solar photography using cameras with a small sensor chip or which use the APS-C format. For cameras with large sensors, a telescope with a larger blocking filter should be used so that the sensor will be illuminated. For solar photography, we generally recommend so-called planetary cameras which work smoothly with this blocking filter.
