Unlike most of the Delos line, this specific focal length utilizes a 2-inch barrel format to accommodate its internal lens geometry while maintaining mechanical stability. In an f\/8 refractor, it produces a 3mm exit pupil, providing a balanced background for observing deep-sky targets like the Hercules Cluster (M13).\u003c\/p\u003e\n    \u003c\/div\u003e\n  \u003c\/div\u003e\n\n  \u003cdiv class=\"DAV-bg-light\"\u003e\n    \u003cdiv class=\"DAV-section\"\u003e\n      \u003ch3\u003eOptical Fidelity and Field Correction\u003c\/h3\u003e\n      \u003cp\u003eBy employing high-index glass and specialized anti-reflection coatings, the 24mm Delos minimizes lateral color and maintains sharp star images across the entire 72° field.
