Nebula Filter CLS 2 "

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

Characteristics:

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

Advantages:

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

Compatibility:

• Compatible with all 2’’ eyepieces

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