Explore Scientific 1.25" 12nm S-II Nebula Filter: Enhances nebula views with precise 12nm passband. 1.25" threaded. Shop now for superior blocking performance!

Become an explorer of the cosmos with the 1.25" 12nm S-II Nebula Filter from Explore Scientific. This powerful tool is designed to enhance your stargazing experience, overcoming the challenges of artificial lighting and sky brightening that often hinder the observation of faint celestial objects beyond our solar system. The Explore Scientific S-II Nebula Filter employs the unique properties of emission nebulae, celestial bodies that emit light in specific colors known as emission lines. These emission lines are associated with certain chemical elements, and in the case of this filter, the focus is on ionized sulfur. Operating at a wavelength of 672 nm, the S-II Nebula Filter selectively allows only the emission lines of ionized sulfur to pass through, effectively blocking all other colors and nearly all artificial light. This results in a dramatic enhancement of your viewing experience, making nebulae visible in areas that would otherwise appear empty without a filter. Whether the sky is slightly brightened or you're in a human settlement with street lights, this filter enables you to effortlessly observe a variety of celestial objects. From planetary nebulae and emission nebulae to supernova remnants, the S-II Nebula Filter makes these astronomical wonders accessible to amateur visual astronomers and astrophotographers alike. Each Explore Scientific Nebula Filter comes with an individual test report, providing assurance of the high-quality product you're receiving. Dive into the depths of the universe with the 1.25" 12nm S-II Nebula Filter and uncover the hidden wonders of the night sky.
