Lunt LS6/12/18CaKMDs2 Ca-K Filter in Extension Tube

1. Optimized Calcium-K Observation: This filter is precisely engineered to isolate the 2.4 Angstrom (Å) bandwidth of the Calcium-K line, revealing intricate structures like the solar granulation and active regions in unparalleled detail. Its specialized design offers a unique perspective on the Sun's dynamic atmosphere.

2. Versatile Blocking Filter Options: Offered with three integrated blocking filter sizes – B600, B1200, and B1800 – to match a wide range of telescope focal lengths. This allows astronomers to select the optimal blocking filter for their instrument, ensuring a well-protected and high-contrast view without introducing vignetting.

3. Robust and Adaptable Design: Housed within a durable straight extension tube, the filter provides easy integration into existing telescope setups. The 2" slide tube connection ensures compatibility with standard focusers, while the inclusion of a 1.25" eyepiece adapter and a T2 thread makes it highly versatile for both visual observation and astrophotography.

4. Precision Engineering for Solar Astronomy: Lunt Solar Systems is renowned for its dedication to solar observation technology. This Ca-K filter exemplifies their commitment to precision, offering reliable performance for capturing the subtle, yet significant, features of the solar disk. The use of original accessories and spare parts is crucial for maintaining the long-term performance and extending the lifetime of such specialized optical equipment.

ABOUT THE LUNT LS6/12/18CAKMDs2 CA-K FILTER

The Lunt LS6/12/18CaKMDs2 Ca-K Filter stands out in the Lunt lineup by offering a dedicated solution for observing the Sun in the Calcium-K wavelength. Unlike broadband white light or Hydrogen-Alpha filters, this model brings into view the granular network, plages, and active regions that are particularly prominent in Ca-K light. Its specialized 2.4 Angstrom (Å) bandwidth ensures that only the desired spectrum of light reaches the observer, providing exceptional contrast for these specific solar features. Available with integrated B600, B1200, or B1800 blocking filters, it caters to telescopes of various focal lengths up to 100mm aperture, ensuring optimal illumination and safety. This filter is an indispensable tool for both amateur and professional astronomers focused on the dynamic surface of our Star. The robust mechanical precision and clear optical path it provides are critical for capturing the subtle changes in the solar atmosphere. Using only original accessories and spare parts from Lunt Solar Systems is highly recommended to prolong the lifetime and maintain the peak performance of this precise instrument.
