The saxon 607AZ2 uses a refractor optical system, which relies on lenses to bend and focus light. The 60mm objective lens gathers light from distant objects and refracts it through a series of glass elements to produce a sharp, upright image. This design is ideal for beginners because it requires minimal maintenance and delivers high contrast views of bright celestial bodies like the Moon and planets. By adjusting the eyepieces, users can explore different magnifications and learn how light behaves when passing through lenses a fundamental principle of optics.
