Lunt Solar Systems Solar telescope ST 70/420 LS60MT Ha B600 Allround OTA (78363)

The LS60MT is a versatile telescope designed for solar observation in H-alpha light, offering a clear 60mm aperture with no central obstruction for sharp, high-contrast images. With this telescope, you can observe solar prominences, filaments, and flares in stunning detail. The integrated etalon filter achieves a bandwidth of less than 0.7 Angstrom, allowing for impressive and dynamic views of the Sun.

A standout feature of the LS60MT is its modular construction. The H-alpha etalon can be detached and replaced with a conversion kit (sold separately), transforming the telescope into a high-quality ED apochromat with FPL-51 glass for night-time astronomy and astrophotography. You can also use a Herschel wedge for white light solar observation or a CaK module for viewing the Sun in the CaK spectral line, making this a truly universal instrument.

The block filter, essential for safe solar observation, is built into the diagonal and accepts both 1.25” eyepieces and cameras, as well as T2-threaded accessories. For night-time use, the blocking filter is not required, and the focuser can accommodate 2” accessories.

The PT pressure tuner allows for precise adjustment of the etalon filter by changing the air pressure inside the telescope, ensuring uniform images and long-lasting performance.
