Lunt Solar Systems Solar telescope ST 80/560 LS80MT Ha B1800 BT R&P Allround OTA (69873)

The LS80MT is a high-performance 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 exceptionally clear 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 B1800 blocking filter is ideal for visual solar observation and for solar photography with cameras that have small sensor chips or APS-C format sensors. For larger sensors, a telescope with a bigger blocking filter is recommended. For solar photography, planetary cameras are generally recommended for best results.
