What is a telescope?
An instrument used to observe distant objects in space.
What is a spectroscope?
An instrument used to measure the properties of light, such as its intensity and wavelength.
What is a sextant?
An instrument used to measure the angles between celestial objects, commonly used in navigation.
What is a planetarium?
A device that displays a model of the solar system, stars, and constellations, used for educational and entertainment purposes.
What is a spectrograph?
An instrument used to produce and record a spectrum of light or radiation.
What is a CCD camera?
A camera that uses charge-coupled device (CCD) technology to capture images of astronomical objects.
What is a radio telescope?
An instrument used to detect and collect radio waves emitted by astronomical objects.
What is an astrolabe?
An ancient instrument used for solving problems related to time and the position of celestial objects.
What is a solar filter?
A filter used to safely observe the Sun and protect the eyes from its intense brightness.
What is a spectroheliograph?
An instrument used to photograph the Sun, specifically its chromosphere and prominences, in various wavelengths of light.
What is an equatorial mount?
A type of telescope mount that allows for precise tracking of celestial objects with the rotation of Earth.
What is an altazimuth mount?
A type of telescope mount that moves vertically (altitude) and horizontally (azimuth), providing simple motion for observing the sky.
What is a spectroheliometer?
An instrument used to measure the intensity of solar radiation at different wavelengths.
What is a star chart?
A map of the night sky that shows the positions and names of stars and other celestial objects.
What is a barlow lens?
An optical device used to increase the effective focal length of a telescope, resulting in magnification of observed objects.
