Daystar Filters Quantum Calcium II K 2Å… PE

Advanced Solar Filter: A 2.0Å PE Quantum Solar Filter, specifically for the Calcium K line (3933.7Å), pivotal in solar research.
Telescope Compatibility: Suitable for use with refractors, SCTs, Maksutovs, enhancing versatility for various telescope types.
Comprehensive Kit: Includes front and rear plates, power supply, instructions, and a hard case for complete setup and secure storage.
Additional Requirements: Requires a UV/IR cut filter and either a Powermate barlow or stop down mask to achieve an optimal F/13-F/35 focal ratio for peak performance (sold separately).
Focus on Calcium Studies: Traditionally used in university research for studying the depth of the solar atmosphere, utilizing the strong Calcium K absorption line.
Preferred Choice for Clarity: Due to its isolation from the Hydrogen Epsilon line and comparable sensor sensitivity, the K line has been the primary choice in Calcium filters.
Quantum Controls for Academic Research: DayStar's Quantum controls on the Calcium II K line are tailored for academic studies, mapping the 3D structure of the Chromosphere with precision.
Wing Shift Precision: Allows for controlled wing shift of the Ca II K line filter with accuracy up to 0.1Å, enabling detailed studies of intensity differences between the K3, K2, and K1 lines.
Solar Atmosphere Observation: Facilitates the observation of complex structures and subordinate peaks in the solar atmosphere, providing views through different levels.
Ideal for Advanced Imaging: Best suited for CCD photography or indoor visual viewing environments, offering high-quality imaging and observation capabilities.
