Lunt Solar Systems Solar telescope ST 80/560 LS80MT Ha B1200 R&P Allround OTA (73870)

The LS80MT is a high-quality telescope designed for observing the Sun in H-alpha light, featuring an 80mm clear aperture and a 560mm focal length. With no central obstruction, this telescope delivers especially sharp and detailed images, allowing the lens to achieve its full resolution. In H-alpha, you can observe solar prominences, filaments, and flares, making every solar session both impressive and dynamic. The integrated etalon filter provides a bandwidth of less than 0.7 Angstrom for high-contrast solar imaging.

A standout feature of the LS80MT is its modular construction. The H-alpha etalon can be easily detached and replaced with a conversion kit (available separately), transforming the telescope into a high-quality ED apochromat with FPL-53 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.

Focusing is achieved with a solid 2-inch rack and pinion drawtube, featuring a 1:10 fine reduction for precise adjustments. The PT pressure tuner allows for fine-tuning of the etalon filter by adjusting air pressure inside the telescope, ensuring uniform images and long-lasting performance.

The B1200 blocking filter is ideal for visual solar observation and for solar photography with cameras that have small sensor chips, such as typical planetary cameras. For larger sensors, a telescope with a bigger blocking filter is recommended.
