DayStar Sodium D-Line Quark

Transform your F/4-F/8 refractor into a high-resolution solar observation instrument with this all-in-one H-alpha Sodium filter. The design combines filter, adapters and snout in a single compact unit.

Why the Sodium line?

  • High-resolution sunspot detail, granulation and super-granulation depending on seeing quality.
  • Observation of flare footprints (solar flames starting with the Sodium ends before the white).
  • Brighter line than Calcium or H-alpha: visible images with short exposure times.
  • D2 filter at 5890 Å with FWHM 0.5 Å or less.
