DayStar Quark Magnesium I b2-line<\/h1>\n

<\/h2>\n

Presentation<\/h2>\n

Visit Quark Magnesium I b2-line<\/strong> opens up a new window of solar observation, revealing
\nstrong areas magnetized<\/strong> of the Sun in the bright Magnesium I (b2)<\/strong> at 5172.8 \u00c5.
\nAs the human eye is particularly sensitive to this wavelength, the image obtained is more \"bright\". such as Calcium, Alpha Hydrogen or even Sodium<\/strong>,
\nwhich greatly facilitates visual observation and reduces exposure time for photography.<\/p>\n

What is the purpose of the Magnesium I b2 filter?<\/h2>\n
    \n
  • Observe active beaches<\/strong> (beach) and large solar magnetic structures.<\/li>\n
  • Detecting dark mottling<\/strong> chromospheric network.<\/li>\n
  • Highlight the Zeeman phenomenon<\/strong>where the absorption line is \"split\" by an intense magnetic field.<\/li>\n
  • Explore areas ofvery high energy activity<\/strong>invisible at other wavelengths.<\/li>\n<\/ul>\n

      Use<\/h2>\n

      Simply insert the Quark Magnesium I b2-line<\/strong> in the angled return<\/strong> of your F\/4 to F\/8 refractor,
      \nadd an eyepiece and observe. No complex adjustments required.<\/p>\n

      \u26a0\ufe0f The use of a suitable energy rejection filter (ERF) is essential to protect your instrument and ensure safe operation.<\/p>\n
