• Blocks Artificial Light: Effectively blocks light from common sources of urban light pollution, including mercury and sodium vapor lamps.
• Optimized for Astrophotography: Designed exclusively for capturing deep-sky objects, especially under challenging brightened sky conditions.
• Enhanced Image Clarity: Reduces interference from artificial light and reveals fine details that are invisible to the naked eye.
• High-Quality Manufacturing: Each filter comes with an individual test report to ensure top-tier performance and precision.
• Durable 2-Inch Design: Fits securely into most standard astrophotography setups, ensuring easy integration with your existing equipment.
• Improves Nebula Visibility: Makes faint, red glowing emission nebulae stand out clearly, even in light-polluted environments.

The Explore Scientific H-Alpha Filter is for you if…

• You’re an urban or suburban astrophotographer struggling with light pollution but still want stunning, high-contrast photos of deep-sky objects.
• You specialize in emission nebula photography and need a reliable filter to capture the full extent of these faint, glowing formations.
• You’ve tried other filters but still find artificial light interference from streetlights and city environments ruining your shots.
• You want a proven, high-quality filter that’s specifically designed for astrophotography, with individual performance testing included.
• You’re looking for a solution to improve image clarity and contrast in environments with moderate to heavy sky brightening.
• You want to unlock the full potential of your telescope and astrophotography equipment to capture deep-space objects in their best detail, even from your backyard.

If you're an astrophotographer frustrated by the overwhelming impact of light pollution, the Explore Scientific H-Alpha 2-inch Filter is the tool you need to drastically improve your imaging results. Designed specifically for emission nebulae photography, this filter uses a precise 7 nm narrow-band pass that isolates the hydrogen-alpha emission line (656.3 nm), allowing you to capture stunning, high-contrast images of deep-sky objects. By blocking nearly all other light wavelengths—including the disruptive artificial light from mercury and sodium vapor lamps commonly found in urban areas—you can finally reveal the rich, red details of nebulae that would otherwise be lost in the glow of the city.

With its 2-inch diameter, this filter is compatible with most standard astrophotography setups, making it an easy upgrade for both experienced and advanced hobbyist photographers. Struggling to capture faint nebulae like the Horsehead Nebula, Rosette Nebula, or the North America Nebula under light-polluted skies? This filter allows you to cut through the ambient glow, revealing the intricate structures and vivid reds of emission nebulae with incredible detail and clarity, even in urban or suburban settings.

Unlike generic filters, the Explore Scientific H-Alpha Filter offers more than just basic light reduction—it’s specifically engineered for astrophotography in light-polluted environments, allowing you to capture deep-sky objects that would normally be invisible. Its 7 nm passband is perfect for isolating the H-alpha wavelength while blocking out nearly all other sources of interference, ensuring you capture nebulae in their purest form.

Every filter undergoes rigorous quality control and comes with an individual test report, so you know you’re getting a high-performance product built for precision. This filter isn't just about improving your astrophotography; it's about unlocking the potential of your setup and allowing you to photograph deep-sky objects as clearly and vividly as possible—even from your backyard in a brightly lit city. If you’re serious about getting the most out of your astrophotography, the Explore Scientific H-Alpha Filter is an essential tool for cutting through light pollution and capturing nebulae with professional-grade results.
