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.
