The Lunt Solar Telescope LS40T Ha B500 R&P 10:1 40/400 is a dedicated H-alpha solar telescope designed to reveal details in the Sun's chromosphere. It can show prominences at the solar limb as well as features such as filaments and active regions across the solar disc.
Its H-alpha system is tuned to the 656.28 nm spectral line. The B500 blocking filter (5 mm) is matched to this configuration. With a 40 mm aperture and 400 mm focal length (f/10), it offers a useful basis for choosing eyepieces and compatible imaging equipment. Please note that models specified as an OTA are supplied without a mount.
Safe solar observing: Use the telescope only when the complete, undamaged H-alpha filter system is correctly assembled, and follow the manufacturer's instructions. Never look at the Sun through the telescope if any part of the solar filter system is missing or damaged.
