DayStar solar filter QUARK Magnesium I (b2) line

Why the Magnesium I (b2) line?

Magnesium is a strongly magnetized element from the sun. The energetic activity temperatures leading to the emission of this line were calculated to be extremely high. Spectroscopically, a "splitting" of the spectral line can be observed, which is called the Zeeman effect. The absorption line "splits" and occurs slightly above and below the typical wavelength at which undisturbed light is absorbed. Strong absorption is seen spectroscopically at 5172Å.

Views in magnesium show solar flares, large-scale magnetic structures, and dark absorbing mottling of the chromospheric structure. The line is brighter than calcium, H-alpha and even sodium. It is therefore very easy to observe and record with short exposure times.

For use on refractors with a focal length ratio of F4 - F/8.
