Omegon Pro Veil H-Alpha OIII Duoband Filter 7nm 2 inch: two channels in one filter<\/strong><\/h2>\n\n\n\n

This filter passes two narrow bands simultaneously: H-alpha and OIII. This allows you to capture both channels in a single exposure, even with a color camera. Where street lighting normally washes out faint details, only the light that truly matters gets through.<\/p>\n\n\n\n

Pro Veil is Omegon's narrow-band series for astrophotography. Each filter comes in a 2-inch aluminum mount with a sturdy protective case.<\/p>\n\n\n\n

Why dual band<\/h4>\n\n\n\n

Using separate narrowband filters requires a monochrome camera and multiple sessions per object. A dual-band filter captures the red hydrogen signal and the blue-green oxygen signal all at once, making it the fastest route to a nebula image for color cameras.<\/p>\n<\/div>\n<\/div>\n\n\n\n

Filter dish for contrast<\/h4>\n\n\n\n

Emission nebulae emit their light in specific bands. This filter transmits precisely those wavelengths and blocks the interfering artificial light in between. This leaves you with a dark background while preserving the characteristic nebula colors.<\/p>\n<\/div>\n<\/div>\n\n\n\n

For which camera<\/h4>\n\n\n\n

A dual-band filter works best with a cooled or uncooled color camera. If you work with a monochrome camera, separate H-alpha and OIII filters provide more control over the ratio between the channels.<\/p>\n<\/div>\n<\/div>\n\n\n\n

Featured accessories<\/h3>\n\n\n\n

Combine with the Pro Veil SII 7nm later if you still want to switch to a full SHO palette.<\/p>\n\n\n\n
