The UHC 2" nebula filter from Explore Scientific is designed to enhance the observation of celestial objects by blocking most artificial light, allowing for the revelation of nebulae invisible to the naked eye under light-polluted skies. This filter exploits the emission lines of hydrogen and oxygen, which are essential for visualizing deep sky objects such as the Owl Nebula or the Dumbbell Nebula.

Features:

• Blocks almost all artificial light
• Passes the emission lines of hydrogen (486 nm, 656 nm) and oxygen (496 nm, 501 nm)
• Diameter: 2’’

Benefits:

• Enhances the contrast of deep sky objects
• Allows viewing of invisible nebulae under slightly illuminated skies
• Perfect for observing faint objects beyond the solar system

Compatibility:

• Compatible with all 2'' eyepieces

Ideal for amateur astronomers looking for additional details in nebula observation. Explore the deep sky with significantly improved image quality thanks to the Explore Scientific UHC filter.
