Nebula Filter H-Beta 2"

The 2" H-Beta nebula filter from Explore Scientific is designed to enhance the observation of emission nebulae, particularly those associated with hydrogen. This filter blocks almost all artificial light and only allows the hydrogen emission lines at 486 nm to pass through, revealing hidden celestial objects under a polluted sky. Ideal for observing hard-to-see nebulae like the Horsehead Nebula, this filter offers exceptional contrast and clarity, even with a slightly lit sky.

Characteristics:

• Diameter: 2”
• Blocks almost all artificial light
• Allows only hydrogen emission lines (486 nm) to pass through
• Improves the visibility of emission nebulae

Advantages:

• Enables observation of invisible nebulae without a filter, such as the Horsehead Nebula
• Increases contrast and sharpness of celestial objects under a slightly polluted sky
• An indispensable tool for amateur astronomers specializing in deep-sky observation

Compatibility:

• Compatible with 2” eyepieces

This H-Beta Explore Scientific filter is perfect for astronomy enthusiasts looking to explore emission nebulae in detail, particularly those dominated by hydrogen.
