Telescopes
Glossary
Magnification
- Thought that the only (or most important) function of telescopes is magnification
- Thought objects could be magnified indefinitely by any telescope with correct lenses
- Thought the only way to change magnification is to use another telescope
- Thought telescopes can have unlimited magnification
- Thought longer telescopes provide more magnification than shorter ones
- Thought telescopes make objects appear their “real” size
- Thought telescopes magnified stars
- Thought mirrors could not be used to magnify
Resolving Power
- Thought telescopes couldn’t resolve planets
- Thought smaller telescopes enable astronomers to see smaller details
- Thought telescopes can resolve stellar surfaces
- Thought optical telescopes could, in principle, see all objects in space
- Thought telescopes can only see stars
- Thought optical telescopes could, in principle, see more matter than other types
- Thought the Dawes’ limit was on magnification
Types/Optics
- Thought radio telescopes transmit signals to stars, rather than receive signals
- Thought reflecting telescopes are inferior to refracting telescopes
- Thought all telescopes use mirrors
- Thought telescope mirrors were coated on their bottom sides
- Thought all lenses are made of glass
- Thought only optical telescopes exist
- Thought non-optical telescopes don’t reveal much, compared to optical telescopes
- Thought all telescopes are refractors
- Thought telescopes never have more than two mirrors
- Thought telescopes require only 1 lens
- Thought telescope lenses/mirrors are flat, circular disks
- Thought secondary mirrors block all the light from certain objects in the telescope’s field of view
- Thought only way to use a telescope is to look in it
- Thought spectroscopes are only used to measure radio waves
- Thought gamma ray telescopes have not been invented yet
- Thought all telescopes are still small
- Thought telescopes primary research guide for astronomers
- Thought lenses are spherical
- Thought Newtonian telescopes are useful for research
- Thought telescope images are right side up
- Thought telescopes were invented by Galileo
- Thought a spectrograph is a type of telescope
- Thought infrared telescopes could be used anywhere
- Thought all telescopes are the same except for size
- Thought telescopes do not change image except for magnification
- Thought refractors use mirrors
- Thought lenses could not sag (due to gravity)
- Thought there is only one type
- Thought all telescopes are reflecting
- Thought a camera instead of a CCD is still the preferred way of producing image in astronomy
- Thought telescopes cannot see beyond the solar system
- Thought light would not bend as it went through glass
- Thought defects such as bubbles do not occur in lenses
- Thought defects with inverted (upside down and backward) images are defective
Hubble/Observatories
- Thought Hubble space telescope is unusable
- Thought warping of Hubble space telescope is inches or feet
- Thought all telescopes are on Earth, that there are none in space
- Thought that observatories are built on mountains or in space is to get them closer to the stars
- Thought telescopes were only used to look at stars
- Thought the Hubble could take sharper images because it was closer
- Thought that Hubble made the Hubble Space Telescope
