The Dual Band filter isolates emission nebula targets using tight 12nm passbands at the critical H-alpha (656.3nm) and O-III (500.7nm) wavelengths. For broader targets, the CLS filter rejects specific sodium and mercury lines from artificial lighting, increasing contrast on everything from galaxies to star clusters.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-bg-light\"\u003e\n\u003cdiv class=\"DAV-section\"\u003e\n\u003ch3\u003eUnlocking Deep-Sky Imaging for Vespera\u003c\/h3\u003e\n\u003cp\u003eThis bundle provides a complete solution for capturing deep-sky objects with your Vespera, whether you're under urban, suburban, or dark skies. By including both a selective narrowband filter (Dual Band) and a versatile broadband filter (CLS), you have the right tool for galaxies, star clusters and nebulae. Each filter is engineered to integrate seamlessly with the Vespera's optical arm, enhancing contrast and revealing faint details that would otherwise be lost to light pollution.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-bg-light\"\u003e\n\u003cdiv class=\"DAV-section\"\u003e\n\u003ch3\u003eDual Band Filter: Isolating H-alpha and O-III with a 12nm Bandwidth\u003c\/h3\u003e\n\u003cp\u003eThe Dual Band is a narrowband interference filter designed for maximum contrast on nebulae.
