With 7-layer Phantom Group coatings working alongside 27-layer dielectric UV/IR treatments, you'll experience minimal ghosting and unwanted reflections during your observation sessions.
Urban Sky Performance
When urban light pollution threatens to dim your astronomical experiences, Baader Moon & Skyglow filters emerge as essential tools for city-based stargazers. These neodymium filters excel in reducing skyglow while preserving image brightness—a critical balance for observing in light-saturated environments.
| Viewing Condition | Without Filter | With Baader Neodymium |
|---|---|---|
| City Center | Washed out sky | Enhanced contrast |
| Suburban Areas | Limited detail | Improved color |
| Moonlit Nights | Diffuse glow | Sharper boundaries |
You'll notice immediate improvements in color contrast as the filter blocks specific wavelengths from streetlights while allowing RGB wavelengths to pass through. Unlike narrowband filters that considerably dim your view, the Baader's transmission profile maintains brightness while effectively combating light pollution, making it ideal for both visual observation and astrophotography in urban settings. The filter's neodymium coating significantly enhances contrast and reduces light pollution effects, delivering a clearer astronomical experience.
Planetary Contrast Enhancement
Despite their brightness in our night sky, planets can still benefit greatly from proper filtration when observed from light-polluted areas.
The Baader Moon & Skyglow filter, with its neodymium-doped glass construction, specifically enhances planetary features while maintaining natural colors and brightness.
When you're targeting planets through urban skyglow, this filter delivers:
