Lunt Calcium K Module

Lunt Calcium K Module - including the B600, B1200, or B1800 Blocking Filter - available in a Diagonal or Straight-Through Tube

Exploring the wavelength of 393.4 nm, Calcium K (Ca-K) telescopes and filters uncover a unique emission line, one of two produced by Calcium at the edge of the optical spectrum. 

Located in a cooler layer beneath Hydrogen-alpha observations, this line reveals vibrant super granulation cells, particularly in regions abundant with magnetic fields like sunspots and active areas. 

The study of both Calcium K and Hydrogen-alpha lines offers invaluable insights into the intricate structure, strength, and depth of these dynamic regions.

Lunt Solar Systems Calcium K modules prove versatile, seamlessly integrating with most standard nighttime refractors or the innovative Modular Telescopes in their nighttime configuration.

Considering the challenge many face in visually perceiving the entirety of what Calcium K has to offer, the utilization of cameras becomes instrumental in unlocking the full potential of this intricate astronomical phenomenon.

Centered at 393.4 nm, this wavelength resides slightly beyond the visible spectrum on the UV side.

Notably, individuals who have undergone cataract surgery often report enhanced visibility of considerable detail. 

However, for comprehensive studies, the Ca-K line is predominantly examined through cameras, capable of capturing stunning details.

The inclusion of internal narrowband filters allows for a <2.4 Angstrom bandpass, emphasizing its role as a primarily imaging system.

Choose the best Calcium K Module for your Telescope Size and Focal Length:

• B600: For telescopes up to 100mm aperture and 600mm focal length

• B1200: For telescopes up to 100mm aperture and 1200mm focal length

• B1800: For telescopes up to 100mm aperture and 1800mm focal length

Features:

• Wavelength Study: Specifically designed for studying the wavelength of 393.4 nm, the LUNT Calcium K (Ca-K) telescopes and filters provide a detailed exploration of this emission line.

• Insights into Solar Activity: By enabling the study of both Calcium K and Hydrogen-alpha lines, the module offers vital insights into the structure, strength, and depth of active solar regions.

• Layer Differentiation: Positioned just at the edge of the visible spectrum, the emission line occurs in a layer slightly lower and cooler than the layer observed in Hydrogen-alpha.

• Super Granulation Cells: The emission line reveals areas of super granulation cells, particularly pronounced in regions with high magnetic fields, such as sunspots and active areas.

• Compatibility with Nighttime Telescopes: Lunt Solar Systems Calcium K modules are versatile, compatible with most standard nighttime refractors, or seamlessly integrated into Lunt's new Modular Telescopes in their nighttime configuration.

• Optimal Usage Range: The Calcium K modules are centered at 393.4 nm, slightly outside the visible spectrum on the UV side, providing a comprehensive view of solar phenomena.

• Visual Perception Challenges: While the violet color is visible to most observers, the contrast may be challenging due to corneal yellowing. Individuals who have undergone cataract surgery often report enhanced detail perception.

• Imaging System with Internal Narrowband Filters: Internal narrowband filters allow for a <2.4 Angstrom bandpass, making the Calcium K module primarily suited for imaging systems. This is due to the difficulty many face in visually perceiving all that Calcium K has to offer.
