Filtre pour Nébuleuse CLS 2’’ - Explore Scientific

The CLS nebula filter 2" from Explore Scientific is specially designed to enhance the observation of deep sky objects by eliminating annoying artificial light, such as that from streetlights and other public lighting sources. This filter blocks typical wavelengths from mercury and high-pressure lamps, allowing emissions from celestial objects to pass through and be observed with greater clarity and contrast. Ideal for observing galaxies and nebulae otherwise invisible under light-polluted skies, like galaxy M101, this filter is an indispensable tool for amateur astronomers.

Features:

• Diameter: 2’’
• Eliminates artificial light from public lighting (mercury and high-pressure lamps)
• Optimized for observing faint deep sky objects

Benefits:

• Significantly improves contrast and sharpness under a polluted sky
• Allows the observation of invisible deep sky objects without a filter
• Perfect for amateur astronomers looking to explore galaxies, nebulae, and other faint objects

Compatibility:

• Compatible with all 2’’ eyepiece holders

The Explore Scientific CLS filter is essential for all amateur astronomers who want to optimize their observations under an illuminated sky.
