  • CNC machined aluminum cell for increased precision and durability
  • Available in 31.75mm and 50.8mm sizes
  • 1.85mm thick Schott glass with double-sided anti-reflective coating
  • Effectively reduces light pollution for clearer images
  • 2-in-1 solution reducing the need for multiple separate filters
