DayStar Combo Quark H-Alpha - For SCT, Mak and F/15-F/30 refractors

The Quark Combo brings the simplicity and security of H-alpha solar observation to owners of SCT, Maksutov and long refractors (F/15-F/30). Choose your version Prominence or Chromosphere for the same price, and benefit from an all-in-one filter that's ready to use, lightweight and compact.

Presentation

The Quark Combo is an H-alpha "All-In-One" device that integrates :

  • Prominence or Chromosphere H-alpha filter (choice)
  • Integrated adapters for direct insertion into your telescope
  • Compact, lightweight design eliminates the need for additional adapters
  • AR surface treatments optimized for 656 nm and internal baffles for enhanced contrast
  • Low power consumption: can run all day with optional battery pack

Important: for SCT and Maksutov, the use of a specific energy rejection filter (ERF) is mandatory for safety and optimum performance.

Prominence versus Chromosphere

Criteria Prominence Chromosphere
Bandwidth FWHM Wider (>0.6 Å) - brighter Narrower (<0.5 Å) - better surface contrast
Filaments Difficult to observe Visible and detailed
Protuberances Very shiny blade Visible but less brilliant
Contrast Less contrast, brightness priority High contrast, ideal for chromospheric detail
Recommended use Quick visual observation Detailed observation and astrophotography

Important instructions for SCT / Maksutov

  • SCT: use an off-axis front-mount ERF with aperture reduction to protect the secondary mirror.
  • Maksutov: ERF front-mount mandatory to avoid overheating the optical tube.
  • F/15-F/30 refractors: insert the Quark Combo directly into the RC, no additional adjustment required.
