The DayStar Combo Quark Prominence is a hydrogen-alpha (H-alpha) solar filter tuned for prominences — the loops and jets of plasma that arc off the edge of the Sun. As a "Combo" model it leaves out the built-in Barlow so you can pair it with your own telecentric lens, making it well suited to larger telescopes and solar imaging.

Supply the telecentric that matches your scope, and the Combo Quark handles the H-alpha tuning that brings solar prominences to life.

Who it's for: Solar observers and imagers with larger refractors who provide their own telecentric Barlow. New to solar filters? See our guide to the best telescope filters for beginners.

  • Tuned for prominences: Optimised to highlight loops and jets at the Sun's limb.
  • Combo design (no built-in Barlow): Works with a separate telecentric lens to match larger scopes and imaging trains.
  • Hydrogen-alpha 656.28nm: Isolates the H-alpha line where prominences and flares appear.
  • Imaging-ready: A common choice for high-resolution H-alpha solar photography.
  • Electronic tuning: A powered tuner shifts the passband for the best prominence contrast.

What does the Prominence tuning show?
It emphasises the loops, jets, and arcs of plasma at the Sun's edge, rather than surface filaments.

What else do I need?
A telecentric Barlow matched to your telescope's focal ratio. DayStar's Combo Quark telecentric Barlows are designed for this.

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