SV115 OIII Filter 2 inch 18nm Reducing Light Polution

Key Features

• Optimized Views of Nebulae

  The 2" O-III filter blocks virtually all visible wavelengths, enhancing views of nebulae by increasing contrast and optimizing the clarity of planetary and gaseous nebulae during visual observation.

• High-Contrast Imaging in Any Sky

  Ideal for large aperture telescopes, this filter provides high-contrast imaging even in light-polluted areas, allowing for superior nebulae observation by permitting only Double Ionized Oxygen lines to pass through at 90%.

• High-Quality Construction

  Crafted from high-grade glass with dichroic interference and anti-reflection coatings, the O-III filter reduces glaring and ghosting, ensuring sharp and clear images of nebulae in various sky conditions.

• Enhanced Contrast for Light-Polluted and Dark Skies

  This narrowband filter works effectively in both light-polluted sites and dark skies, boosting contrast and making it easier to see nebulae without brightening the object, making it perfect for astrophotography.

• Compatible with 2" Eyepieces

  The 2" O-III filter is compatible with all 2" eyepieces, providing a versatile solution for astrophotography and visual astronomy, especially when using large telescopes to observe faint nebulae and deep-sky objects.
