LS130 accessory: CaK (calcium) module

CaK module for LS130T

Visit CaK module for LS130T allows you to explore the Sun in the Calcium K (CaK) around 393.4 nm, a wavelength in the near ultraviolet. This spectral band reveals structures different from those visible in H-alpha, notably active regions and solar patches.

Observation in Calcium K

Unlike H-alpha, which reveals protuberances and filaments, CaK reveals :

• Bright patches around active regions
• Intense magnetic zones
• High chromospheric granulation
• The evolution of solar activity cycles

CaK is particularly appreciated in solar imagery, where it offers a remarkable contrast on active areas.

Compatibility

• Designed specifically for LS130T
• Direct integration into the optical system
• Optimized to work with the full 130 mm aperture

The module takes full advantage of the LS130T's resolution, offering superior detail.

Recommended use

The CaK wavelength lies in an area of the spectrum where human visual sensitivity is low. Therefore :

• Use is mainly oriented towards imaging
• Visual observation may be limited depending on the observer's sensitivity

In solar astrophotography, CaK is an ideal complement to H-alpha for documenting solar activity from a variety of physical angles.

Why add a CaK module?

• The perfect complement to H-alpha
• Detailed analysis of active regions
• A scientific approach to solar activity
• Maximizing the potential of the LS130T

Visit CaK module for LS130T transforms your instrument into a complete solar platform, capable of exploring many layers and phenomena of our star.
