Observational Instruments & Methods Presentation

Astronomical observation is the detection of observational values of celestial objects or a stellar event via bare eyes or by using technical instruments.

Examples of technical instruments used in astronomical observation include telescopes, spectrographs, CCD cameras, photometers, and photographic plates.

An observatory is a place equipped with specific technical instruments for astronomical observation to observe celestial objects.

<p>The text mentions four types of observatories: ground-based, airborne, space-based, and underground-based.</p> Signup and view all the answers
