The 2" 12nm H-Alpha filter from Explore Scientific is specifically designed for astrophotography, providing an effective solution for capturing emission nebulae under polluted skies. This filter blocks almost all artificial light, notably that from mercury and sodium vapor lamps, and only allows the emission line of red hydrogen to pass through. This enables the revelation of hidden details and captures nebulae that would otherwise be invisible. With a bandwidth of 12nm, this filter significantly enhances the contrast and sharpness of deep sky objects, even in urban observing conditions. An essential accessory for astrophotographers looking to achieve exceptional images despite light pollution. Each filter comes with an individual test certificate ensuring its high quality.
