Lumicon H-Alpha Night Sky 1.25 inch Filter (Pre-owned)

Key Features:

1. Wavelength Isolation:

   • Transmits light centered around the H-alpha emission line, allowing for detailed observation of hydrogen-rich regions such as nebulae.
   • Blocks other wavelengths to improve contrast and reduce light pollution or unwanted skyglow.

2. Compatibility:

   • Fits standard 1.25-inch eyepieces, cameras, or other optical accessories.
   • Ideal for telescopes with moderate to large apertures for visual or photographic use.

3. High-Quality Construction:

   • Made with precision multi-coated glass for optimal performance and durability.
   • Encased in a durable metal cell for secure mounting and easy handling.

4. Applications:

   • Visual Use: Enhances the visibility of emission nebulae by improving contrast against the night sky.
   • Astrophotography: Essential for imaging deep-sky objects like the Orion Nebula, Horsehead Nebula, and other hydrogen-rich targets.

5. Performance:

   • Best used under dark skies with minimal artificial light pollution.
   • Recommended for use with monochrome cameras or astrophotography setups for capturing detailed H-alpha data.
