Explore Scientific 1.25" CLS Nebula Filter

Enhanced Contrast: This CLS (City Light Suppression) filter significantly improves the visibility of emission nebulae and other faint deep-sky objects by blocking specific wavelengths of light emitted by common streetlights and other artificial sources, while allowing the crucial light from nebulae to pass through. This makes astrophotography more vibrant and visual observations clearer.
Broad Spectrum Use: Unlike narrowband filters, the CLS filter is a broadband filter, making it versatile for observing a wider range of nebulae and galaxies in urban or suburban environments. It effectively cuts light pollution without excessively dimming the entire field of view, maintaining a more natural appearance.
Premium Optical Coating: Features high-quality, multi-layer anti-reflection coatings on both surfaces of the optical glass. This ensures maximum light transmission and minimizes internal reflections, preventing ghosting and flares for a clear, crisp image, crucial for discerning faint astronomical details.
Precision Construction: Housed in a durable, black anodized aluminum cell that is precisely machined to ensure accurate threading and a secure fit. The robust construction ensures the filter maintains its optical integrity and provides long-lasting performance, even with frequent use and temperature changes. Explore Scientific's commitment to quality ensures each filter is a reliable tool for astronomers.

ABOUT THE EXPLORE SCIENTIFIC 1.25" CLS NEBULA FILTER

The Explore Scientific 1.25" CLS Nebula Filter stands out by offering a cost-effective yet highly efficient solution for combating light pollution during deep-sky observations and astrophotography. Unlike more specialized narrowband filters, this CLS filter employs a broadband approach, allowing a wider range of light from nebulae to pass through while effectively blocking major light pollution wavelengths associated with high-pressure sodium and mercury vapor lamps. This makes it particularly effective for enhancing the contrast of common emission nebulae, supernova remnants, and planetary nebulae from light-polluted areas, providing a darker sky background and making faint objects much more discernible. Its multi-layer coatings ensure maximum light transmission and minimal internal reflections, preserving the delicate details of celestial objects. This filter is an essential tool for urban and suburban astronomers looking to unlock the full potential of their telescopes. The use of original accessories and spare parts, such as this filter with its robust housing and protective case, ensures prolonged product lifetime and consistent performance.
