Omegon Pro Veil OIII Filter 3nm 2 inch: 3 nm transmission at the oxygen lines<\/strong><\/h2>\n\n\n\n

This filter cuts the passband back to 3 nanometers around the emission lines of doubly ionized oxygen. It acts like a spotlight on nebulae: interfering light is blocked, only the oxygen light 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

More contrast, immediately visible<\/h4>\n\n\n\n

The filter blocks both street lighting and natural skyglow. The background remains dark and nebula structures stand out sharply, even in captures from a light-polluted environment.<\/p>\n<\/div>\n<\/div>\n\n\n\n

The trade-off compared to 7 nm<\/h4>\n\n\n\n

The narrower band results in a lower background signal, but also lets through less stray light. With a fast lens, that\u2019s a good trade-off; with a long brand aspect ratio, it requires merk more exposure time.<\/p>\n<\/div>\n<\/div>\n\n\n\n

Working consistently<\/h4>\n\n\n\n

If you are building an SHO set, choose the same bandwidth for all channels. That keeps the exposure times per channel comparable and makes combining them easier.<\/p>\n<\/div>\n<\/div>\n\n\n\n

Combine with the Pro Veil H-Alpha 3nm and Pro Veil SII 3nm for a consistent 3 nm set.<\/p>\n\n\n\n
