**Telescope Eyepieces: Optical Theory and Design ** explores the wide range of eyepiece designs. It introduces optics theory progressively to build understanding of how lenses control light in an optical system generally and in eyepieces specifically, linking optics fundamentals, design evolution and the implications for image quality.
