Herschel Lunt Calcium-K Prism: Solar observation in the Calcium-K line

The Herschel Lunt Calcium-K prism is a high-precision accessory designed specifically for the LS130MT modular telescope. This tool enables observation of the Sun in the Calcium-K (Ca-K) line, centered on the 393.4 nm wavelength, while offering maximum safety and outstanding image quality. Highlighting the intense magnetic zones and dynamic structures of the solar chromosphere, this prism is ideal for astrophotographers and enthusiasts wishing to explore a unique facet of the Sun.

Scientific operation: The Calcium-K line and the Herschel prism

The Calcium-K line is produced by the ionization of calcium in the solar chromosphere, revealing details such as supergranulation cells, active regions and sunspots. Herschel's prism deflects around 95 % of sunlight and heat into an integrated light trap, while the remaining 5 %, attenuated by internal filters, is transmitted to the eyepiece or camera. This process guarantees safe observation while maintaining superior sharpness and contrast.

Key features

  • Specific wavelength : Optimized for the Calcium-K line (393.4 nm), revealing complex magnetic structures.
  • Exclusive compatibility : Designed specifically for the LS130MT modular telescope.
  • Secure filtering : Complete with light trap and internal filters to ensure safe use.
  • Advanced observation and imaging : Ideal for capturing fine details thanks to its compatibility with modern cameras.
  • Robust case : Made from precision-machined aluminum, guaranteeing durability and reliability.

Why choose the Herschel Lunt Calcium-K prism for LS130MT?

  • Explore a unique facet of the Sun: Observe fascinating details such as fine granulation, sunspots and active regions under near-ultraviolet light.
  • Exceptional optical quality: Offering high contrast and optimum sharpness thanks to precise filtering.
  • Absolute safety : Designed with an integrated light trap to eliminate any risk during sun observation.
  • Perfect compatibility with LS130MT : Easily integrated into the telescope's modular system, enabling smooth transition between different observation modes (H-alpha, white light, Ca-K).

Recommended applications

  • Advanced solar astrophotography : Capture spectacular images of the Sun in near-ultraviolet light.
  • Study of solar magnetic fields : Analyze active zones and follow the evolution of sunspots with precision.
  • Limited visual observation : For those able to perceive the Ca-K line (especially after cataract surgery).
