Celestron UHC/LPR Filter - 1.25"

Celestron UHC/LPR Filter - 1.25"

• Selective Light Transmission: Designed to filter specific wavelengths from artificial light sources like mercury vapor, sodium vapor lights, and sky glow.
• Enhanced Contrast: Offers improved contrast with darker sky backgrounds, making emission nebulae more visible.
• Exceptional Optical Quality: Boasts over 97% transmission across the entire bandpass, ensuring bright and clear views.
• Advanced Coating Technology: Utilizes multi-layer dielectric coatings, plasma-assisted and Ionbeam hardened for durability and scratch resistance.
• Optimal for Various Telescope Sizes: Ideal for users of smaller telescopes (4"-11") due to high efficiency and also perfect for larger scopes for detailed views.
• Natural Viewing Experience: Maintains a natural look with a moderate 60nm passband while significantly enhancing overall contrast.
• Broad Bandpass with H-Alpha Efficiency: Suitable for imagers with a broad bandpass and an efficient H-Alpha passband (656nm).
• Light Pollution Reduction: Excellent for observing nebulae in light-polluted areas or enhancing contrast in darker locations.
• Preserves Detailed Nebular Shadings: Allows for rich star fields and intricate nebular details to be observed intact.
• Versatile Use: Enhances both visual observation and astrophotography in varied light conditions.
