Lunt Solar Systems Solar telescope ST 40/400 LS40T Ha B1200 (72099)

The Lunt Solar Systems ST 40/400 LS40T Ha B1200 is a complete solar telescope designed for observing the Sun in H-alpha light. It features a 40 mm aperture and 400 mm focal length, providing clear views of solar prominences, filaments, flares, and other details on the Sun’s surface. The telescope uses an Etalon with mechanical tilt-tuning to achieve a bandwidth of less than 0.7 Angstrom, allowing for impressive solar observations. The included B1200 blocking filter is suitable for visual solar viewing and is compatible with cameras that have small sensor chips, such as typical planetary cameras. For cameras with larger sensors, a telescope with a larger blocking filter is recommended to ensure proper sensor illumination.
