How do you make a replica telescope?
Instructions
- Calculate the distance between lenses: Subtract the focal length of the concave lens (curves inward) from that of the convex lens (curves outward). …
- Drill a hole in the center of the end cap. …
- Glue the convex lens to the inside of the cardboard tube.
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.
Would it be possible for a telescope to use concave lenses?
A telescope can also be made with a concave mirror as its first element or objective, since a concave mirror acts like a convex lens as seen in Figure 3. Flat mirrors are often employed in optical instruments to make them more compact or to send light to cameras and other sensing devices.
What type of telescope is a Dobsonian?
reflecting telescope A Dobsonian is a reflecting telescope (uses a mirror, not a lens) in the same design as a Newtonian telescope (concave collecting mirror is at the rear of the telescope tube, eyepiece is on the side of tube, up near the front).
What was Galileo’s telescope?
refracting 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 long was Galileo’s telescope?
Galileo's famous telescope for observing Jupiter's moons had a convex lens with a focal length of about 30-40 inches and a concave ocular lens of about 2 inches, contained in a little tube that could be adjusted for focusing.
