telescope optics

Telescope optics involve the use of lenses or mirrors to collect and focus light from distant objects, allowing us to see them more clearly. The primary component, the objective lens or mirror, gathers light and forms an image, while an eyepiece lens magnifies that image for viewing. There are two main types of telescopes: refractors, which use lenses, and reflectors, which use mirrors. The design and quality of these optical components determine the telescope's ability to resolve fine details and collect light, enabling observations of celestial bodies like stars, planets, and galaxies.
