The DayStar Calcium Quark Filter is a precision solar filter designed to isolate the Calcium K (Ca K) spectral line, providing detailed views of the Sun’s chromosphere at a wavelength of 393.4 nm. This specialized filter reveals solar features such as plages, faculae, filaments, and magnetic network patterns that are invisible in broadband light, offering a unique and scientifically rich solar observing experience.
Engineered as a compact, eyepiece-style unit, the Calcium Quark integrates a high-quality etalon and blocking filter into a single self-contained device. Its electronic thermal regulation maintains a stable, narrow bandpass for consistent, high-contrast performance, whether for visual observation or high-resolution imaging. The filter is designed for easy installation into standard telescope focusers and operates via a simple 5V USB connection.
