    This OIII filter particularly enhances planetary nebulae in larger telescopes.

    • Optical quality BK7 glass yields sharp star images, even when filter is placed in front of diagonal.
      100% quality control:
    • Every single filter is checked optically and cosmetically to assure performance.
    • Every filter is individually serialized.
