Lunt LS6/12/18CaKMDd2 Ca-K Filter in 90° Star Diagonal

1. Advanced Calcium-K Observation: This specialized filter is designed for observing the Sun's atmosphere in the Calcium-K (Ca-K) spectral line, providing unique views of features like spicules and plages. Its narrow bandwidth of <2.4 Angstrom ensures high contrast and detailed imagery.

2. Versatile Blocking Filter Options: The integrated B600, B1200, and B1800 blocking filters offer flexibility for various telescope focal lengths, all while maintaining compatibility with telescopes up to 100mm aperture. This allows users to optimize their setup for different observation or imaging needs.

3. Ergonomic 90° Diagonal Design: Housed within a 90° star-diagonal, this filter provides a comfortable viewing position, especially during extended observation sessions. The design integrates seamlessly into existing telescope setups.

4. Robust Mechanical Precision: Engineered for reliability, the filter features a 2" slide tube and 1.25" eyepiece connection, along with a T2 thread for imaging. This mechanical robustness ensures stable performance and precise alignment for a superior solar observation experience. Using original accessories and spare parts will prolong the lifetime of Lunt products.

ABOUT THE LUNT LS6/12/18CAKMDD2 CA-K FILTER

The Lunt LS6/12/18CaKMDd2 Ca-K Filter stands out in the Lunt Solar Systems lineup due to its versatile, integrated blocking filter system that offers three distinct options (B600, B1200, B1800) within a single unit. This versatility allows observers to adapt the filter to various telescope focal lengths while maintaining compatibility with instruments up to 100mm aperture. Designed specifically for solar observation, this filter excels in revealing the Sun's intricate structures in the Calcium-K spectral line, an area rich in chromospheric activity. Its remarkably narrow bandwidth of less than 2.4 Angstrom ensures exceptional contrast and clarity, making it ideal for both visual observation and astrophotography of solar features like spicules, plages, and active regions. The robust mechanical design, including its 90° diagonal housing, a 2" focuser slide tube, and T2 camera thread, emphasizes precision and ease of use for dedicated solar enthusiasts. Consistent use of original accessories and spare parts is crucial for ensuring the longevity and optimal performance of this high-precision instrument.
