Galilean telescope magnification

The Galileo Galilei telescope, known as the Galilean refractor, is a pioneering instrument in astronomy. Galileo did not invent the telescope but significantly improved its design after hearing about the &#;Dutch perspective glasses&#; in

Galileo Galilei telescope consisted of a main tube with separate housings for the objective and eyepiece lenses.

Galilean telescope used a simple arrangement of lenses to magnify objects, similar to a pair of opera glasses. Galileo&#;s initial telescope magnified objects 3x, which he later refined to 20x. The original Galileo telescope had a power magnification, featuring a 37 mm objective lens and a 13 mm eyepiece.

Galileo&#;s telescope worked by using a combination of two lenses: a large converging lens (objective) and a smaller diverging lens (eyepiece).

This configuration allowed for a magnified and upright image, enabling significant astronomical observations and discoveries.

The objective lens in Galileo&#;s telescope was convex, with a d
