The basic tool that Galileo used was a crude refracting telescope. His initial version only magnified 8x but was soon refined to the 20x magnification he used for his observations for Sidereus nuncius. It had a convex objective lens and a concave eyepiece in a long tube.The basic tool that Galileo used was a crude refracting telescope.

What was the magnification of the first telescope?
3x magnification Galileo spent his time to improving the telescope, producing telescopes of increased power. His first telescope had a 3x magnification, but he soon made instruments which magnified 8x and finally, one nearly a meter long with a 37mm objective (which he would stop down to 16mm or 12mm) and a 23x magnification.
What did Galileo view with his first telescope?
Galileo made his first telescope in 1609, modeled after telescopes produced in other parts of Europe that could magnify objects three times. … With this telescope, he was able to look at the moon, discover the four satellites of Jupiter, observe a supernova, verify the phases of Venus, and discover sunspots.
What was Galileo’s best telescope?
Galilean telescope Galilean telescope The design Galileo Galilei used c. 1609 is commonly called a Galilean telescope. It used a convergent (plano-convex) objective lens and a divergent (plano-concave) eyepiece lens (Galileo, 1610).
What magnification was Galileo’s telescope?
Galileo's Telescopes The basic tool that Galileo used was a crude refracting telescope. His initial version only magnified 8x but was soon refined to the 20x magnification he used for his observations for Sidereus nuncius. It had a convex objective lens and a concave eyepiece in a long tube.
How strong were Galileo’s telescopes?
Through refining the design of the telescope he developed an instrument that could magnify eight times, and eventually thirty times. This increased magnification of heavenly objects had a significant and immediate impact.
How did Galileo change the telescope?
Between the summer 1609 and the beginning of January 1610, Galileo increased the magnification of his telescope by a factor of 21. He also introduced a number of modifications, such as the ability to control its aperture, that helped to reduce optical aberrations.
What did Galileo’s telescope do?
Galileo's telescope Galileo was the first to point a telescope skyward. He was able to make out mountains and craters on the moon, as well as a ribbon of diffuse light arching across the sky — the Milky Way. He also discovered the rings of Saturn, sunspots and four of Jupiter's moons.
How Galileo’s telescope works?
In Galileo's version, light entering the far end (1) passed through a convex lens (2), which bent the light rays until they came into focus at the focal point (f). The eyepiece (3) then spread out (magnified) the light so that it covered a large portion the viewer's retina and thus made the image appear larger.
