Daystar Filters 2" UV/IR Filter for Refractors (SKU: DSIUV2) is an energy rejection filter designed for H-alpha solar observing systems. Installed in the optical path of a refractor telescope, it reduces ultraviolet and infrared radiation reaching the H-alpha filter assembly, lowering thermal load and improving the stability of systems such as DayStar Quark or Quantum filters.

Key features

• UV/IR rejection filter designed for H-alpha solar observation systems
• reduces ultraviolet and infrared radiation in the optical path
• lowers thermal load on solar filters and optical components
• improves operational stability of DayStar H-alpha filters
• designed for use with refractor telescopes
• standard 2" accessory format

Box contents
