LS40T H-alpha 40 mm solar telescope - B500 blocking filter & helical focuser<\/h2>\n

This 40 mm H-alpha solar telescope<\/strong> is designed for detailed observation of the Sun
\nin the H-alpha line (656.28 nm). Compact, lightweight and easy to use,
\nit lets you explore solar activity in complete safety:
\nprotuberances, filaments, sunspots, spicules and surface structures.<\/p>\n

Equipped with a B500 blocking filter<\/strong> and a precise helical focuser<\/strong>,
\nit's the ideal solution for high-resolution visual solar observation.<\/p>\n

\n

Dedicated H-alpha observation<\/h3>\n

The optical system is optimized to isolate the H-alpha spectral band,
\nrevealing dynamic phenomena in the solar chromosphere that are invisible in white light.<\/p>\n
