The Lunt Solar Telescope LS80MT Ha B1800 PT R&P Allround OTA 80/560 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; Pressure Tuning allows the etalon to be finely adjusted to the H-alpha line. The B1800 blocking filter (18 mm) is matched to this configuration. With an 80 mm aperture and 560 mm focal length (f/7), it offers a useful basis for choosing eyepieces and compatible imaging equipment. The optical design uses an FPL-51 ED doublet. 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.
