DayStar Quark Magnesium I b2-line

Presentation

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

What is the purpose of the Magnesium I b2 filter?

  • Observe active beaches (beach) and large solar magnetic structures.
  • Detecting dark mottling chromospheric network.
  • Highlight the Zeeman phenomenonwhere the absorption line is "split" by an intense magnetic field.
  • Explore areas ofvery high energy activityinvisible at other wavelengths.

Technical specifications

Wavelength 5172.8 Å (Magnesium line I b2)
Bandwidth ≈ 0.4 Å or narrower
Compatible telescopes F/4 to F/8 refractors
Optical elements Fabry-Perot stallion, without integrated Barlow
ERF compatibility Specific ERF filters required - red or yellow glass filters do not allow Magnesium to pass through. UV/IR cut filter recommended for added safety.

Power supply USB 5V 1.5A - all-day operation with optional compact battery
Blocking Integrated 25 mm blocking filter, 21 mm clear aperture
Warranty 5 years

Highlights

  • Much brighter image than Calcium, Hα or Sodium → easier to observe.
  • Reveals magnetic and chromospheric structures invisible in other bands.
  • Compact design, no additional accessories required.
  • Anti-reflective coatings optimized for 517 nm, with internal diaphragms for enhanced contrast.

Use

Simply insert the Quark Magnesium I b2-line in the angled return of your F/4 to F/8 refractor,
add an eyepiece and observe. No complex adjustments required.

⚠️ The use of a suitable energy rejection filter (ERF) is essential to protect your instrument and ensure safe operation.

Package contents

  • Quark Magnesium I b2-line with integrated blocking filter
  • 90-240 V mains adapter with international plugs
  • Rigid carrying case
