UHC 1,25" nebula filter from Explore Scientific is an essential tool to enhance your astronomical observations. This filter blocks most artificial light, allowing you to reveal nebulae that you would not otherwise see under a polluted sky. By only allowing the emission lines of hydrogen and oxygen to pass through, this filter optimizes the visibility of deep-sky objects, such as the Owl Nebula or the Cirrus Nebula.

Features:

• Diameter: 1.25’’
• Blocks almost all artificial light
• Lets through the emission lines of hydrogen (486 nm, 656 nm) and oxygen (496 nm, 501 nm)

Benefits:

• Significantly increases contrast for better observation of nebulae
• Allows detection of celestial objects that are difficult to see without a filter
• Improves clarity of observations under a slightly illuminated sky

Compatibility:

• Compatible with 1.25’’ eyepiece holders

This UHC filter from Explore Scientific is ideal for amateur astronomers looking to enhance their deep-sky celestial observation experience.
