Lunt LS100MT H-alpha solar telescope, B3400 FT

The LS100MT is Lunt's 100 mm universal day-and-night modular telescope, built on an FPL53 ED triplet. The internal Doppler True pressure-tuned etalon gives uniform H-alpha bandpass; with the solar module removed it is a 100 mm f/7 apochromatic refractor.

Safety

Always use the telescope with its Lunt blocking filter in place; it is a dedicated solar instrument in H-alpha configuration.
