Celestron UHC/LPR Filter - 2"

Celestron UHC/LPR Filter - 2"

• Targeted Light Pollution Reduction: Designed to decrease transmission of specific wavelengths from artificial lighting, including mercury and sodium vapor lights.
• Enhanced Ultra High Contrast: Offers improved contrast compared to standard broadband filters, providing darker skies and more distinct emission nebulae.
• Advanced Coating Technology: Utilizes multi-layer dielectric coatings, plasma-assisted and Ionbeam hardened for scratch resistance and durability.
• Exceptional Light Transmission: Achieves over 97% transmission across the entire bandpass, effectively blocking major light pollution lines.
• Ideal for Various Viewing Conditions: Excellent for observing nebulae in light-polluted skies or enhancing nebular contrast in darker areas.
• Optimized for Different Telescope Sizes: Suitable for smaller telescopes (4"-11") due to high efficiency and great for larger telescopes for rich star fields and detailed nebular observations.
• Natural Viewing Experience: Maintains a more natural view with a moderate 60nm passband, significantly enhancing overall contrast.
• Broad Bandpass with H-Alpha Efficiency: Favored by imagers for its wide bandpass and highly efficient H-Alpha passband (656nm).
• Maximum Image Brightness and Contrast: Improved transmission ensures brighter images and pronounced contrast.
• Versatile for Observation and Imaging: Enhances both visual and photographic experiences in diverse lighting environments.
