Available within 7 days
The H-Beta 2" 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 celestial objects hidden under a polluted sky. Ideal for observing difficult-to-see nebulae, such as the Horsehead Nebula, this filter offers exceptional contrast and clarity, even with a slightly illuminated sky.
