Lunt LS60MT H-alpha solar telescope, B1200 The LS60MT is Lunt's universal day-and-night modular telescope. A 70 mm FLP51 ED doublet forms the base instrument; with the H-alpha module fitted it works at 60 mm aperture with an internal Doppler True pressure-tuned etalon. Remove the solar modules and it becomes a 70 mm ED refractor for night use.
