Details
The Magnesium I b2 Line Quark is a precision solar filter designed for amateur astronomers and astrophotographers using refractor telescopes. It reveals the sun's magnetic activity at a bright green wavelength where the human eye is most sensitive, delivering clearer and more detailed views of solar phenomena such as plages and chromospheric mottling.
Engineered for simplicity and performance, this compact filter integrates all necessary optical components into a single, lightweight device that fits directly into your telescope's diagonal. It is ideal for observers seeking to explore magnetic structures and high-energy solar regions with short exposure times and enhanced contrast.
Optimized Optical Design
The filter incorporates a custom 4.2X telecentric barlow lens that ensures a flat field and sharp images across the viewing area. Anti-reflection coatings are specifically tailored for the 5172.8Å magnesium wavelength, maximizing light transmission and contrast.
Magnetic Solar Detail
Observations at this wavelength enable the detection of Zeeman splitting, a spectral signature indicating magnetized solar regions. This allows users to study the sun's complex magnetic structures and dynamic chromospheric features with exceptional clarity.
Ease of Use
Designed for F/4 to F/8 refractor telescopes, the filter requires no additional adapters or complex setup. Simply insert it into your diagonal, attach an eyepiece, and begin observing. The device comes with both 1.25" and 2" eyepiece snouts to match your equipment.
Compact and Efficient
The streamlined design reduces weight and eliminates unnecessary parts, making it portable and convenient. Its low power consumption allows operation throughout the day using an optional small battery pack, enhancing field usability.
Enhanced Contrast and Safety
Integrated baffles suppress stray light to boost image contrast, while the filter requires pairing with a specific energy rejection filter for safe solar viewing. This ensures your observations are both spectacular and secure.
