LS40T H-alpha 40 mm solar telescope - B500 blocking filter & helical focuser

This 40 mm H-alpha solar telescope is designed for detailed observation of the Sun
in the H-alpha line (656.28 nm). Compact, lightweight and easy to use,
it lets you explore solar activity in complete safety:
protuberances, filaments, sunspots, spicules and surface structures.

Equipped with a B500 blocking filter and a precise helical focuser,
it's the ideal solution for high-resolution visual solar observation.


Dedicated H-alpha observation

The optical system is optimized to isolate the H-alpha spectral band,
revealing dynamic phenomena in the solar chromosphere that are invisible in white light.

  • Disc edge protuberances
  • Filaments and eruptions
  • Fine details of the solar surface
  • Rapid changes in solar activity

B500 blocking filter

Visit blocking filter B500 ensures image security and spectral purity.
It is particularly suited to visual observation with standard 1.25″ eyepieces.

  • Compact and lightweight
  • Ideal for solar visuals
  • Simple integration into the optical chain

Precise helical focuser

The eyepiece holder helical for smooth, fine-tuning,
essential to fully exploit resolution in solar observation.
Its compact design helps maintain a lightweight, well-balanced package.


Accessories included

  • TeleVue Sol Searcher for fast, secure solar pointing
  • Dovetail 4″ for mounting on compatible frames

The Sol Searcher enables the telescope to be precisely aligned with the Sun
without having to look directly at the star, ensuring safe and efficient pointing.
