Lunt Solar Systems Solar telescope ST 130/910 LS130MT Ha B3400 Allround OTA (85173)

The Lunt Solar Systems ST 130/910 LS130MT Ha B3400 Allround OTA is a versatile solar telescope designed for detailed observation of the Sun in H-alpha light. It features a modular construction that allows easy removal of the H-alpha filter, making it suitable for both solar and nighttime observations. The telescope can be expanded for additional solar observation modes, such as using a Herschel wedge for white-light viewing or swapping the H-alpha filter for a Ca-K module. The high-quality triplet apochromat lens with an ED element ensures excellent color correction and clarity, making this instrument ideal for both solar and planetary observations. The telescope is equipped with a Feather Touch focuser, providing smooth and precise adjustments for a wide range of accessories. The pressure tuner enables fine-tuning of the H-alpha filter, ensuring a uniform and clear solar image. The permanently installed B3400 blocking filter in the 2-inch focuser is especially suitable for solar imaging with large-sensor cameras, as well as visual observation.
