The DayStar Quark Magnesium I is a specialty solar filter that lets you observe the Sun in the magnesium I (Mg I) spectral line — a wavelength that reveals its own layer of solar atmospheric detail. It's a way for experienced observers to study the Sun beyond the familiar hydrogen-alpha view.

Like the rest of the Quark eyepiece line, it slips into your focuser like an eyepiece and includes its own magnifying lens, making it a self-contained addition to a solar observing kit.

Who it's for: Advanced solar observers who want to explore the Sun in the magnesium I line. New to solar filters? See our guide to the best telescope filters for beginners.

  • Magnesium I line viewing: Tuned to the Mg I spectral line for a distinctive solar view.
  • Reveals a different layer: Shows solar atmospheric structure not seen in hydrogen-alpha.
  • Built-in telecentric Barlow: Supplies the correct light cone and adds magnification in one unit.
  • Eyepiece-style installation: Drops into a 1.25" focuser with no permanent changes to your scope.
  • Electronic tuning: A powered tuner shifts the passband to optimise the view.

What does the magnesium I line show?
It isolates a solar wavelength that reveals atmospheric detail complementary to hydrogen-alpha, of interest to dedicated solar observers.

What telescope works best?
A small refractor around f/4 to f/8. The built-in telecentric Barlow provides the required light cone.

Is it safe for solar observing?
Yes, when used as directed with a compatible refractor. Always follow DayStar's setup and aperture guidance for safe solar viewing.
