Lunt Solar Telescope LS50THa/B400PT 50/350

The Lunt Solar Telescope LS50THa/B400PT 50/350 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 B400 blocking filter (4 mm) is matched to this configuration. With a 50 mm aperture and 350 mm focal length (f/7), 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.
