OPTOLONG 2" 18nm O-III Filter

Capture stunning and detailed images of celestial objects with the OPTOLONG 2" 18nm O-III filter. This high-quality narrowband filter effectively blocks light pollution and enhances the visibility of nebulae and other faint objects in the night sky.

This helps to reveal the intricate details and structures of nebulae, such as the Veil Nebula, the Ring Nebula, and the Helix Nebula.

The filter is compatible with any 2" filter holder and is easy to install, allowing for hassle-free astrophotography. Made with high-quality optical glass and coated with multiple layers of anti-reflection materials, the OPTOLONG 2" 18nm O-III filter ensures maximum transmission and a clear, sharp image.
