40 mm H-alpha solar telescope - B1200 blocking filter & Helical eyepiece holder

This 40 mm H-alpha solar telescope is dedicated to detailed observation of the solar chromosphere in the H-alpha line (656.28 nm). Compact, lightweight and easy to set up, it enables safe exploration of the solar protuberances, filaments, active regions and fine surface structures.

This version is equipped with a B1200 blocking filter, offering an even more generous useful field, as well as a helical eyepiece holder precise and fluid.


H-alpha solar observation

Optimized to isolate the H-alpha band, this system reveals the dynamics of the solar chromosphere, invisible in white light:

  • Disc edge protuberances
  • Filaments and solar flares
  • High-contrast fine surface details
  • Tracking solar activity day by day

B1200 blocking filter - maximum comfort
