37 Questions
What is the definition of astronomical observation?
Astronomical observation is the detection of observational values of celestial objects or a stellar event via bare eyes or by using technical instruments.
What are some examples of technical instruments used in astronomical observation?
Examples of technical instruments used in astronomical observation include telescopes, spectrographs, CCD cameras, photometers, and photographic plates.
What is the definition of an observatory?
An observatory is a place equipped with specific technical instruments for astronomical observation to observe celestial objects.
What are the different types of observatories mentioned in the text?
The text mentions four types of observatories: ground-based, airborne, space-based, and underground-based.
What is a key property of astronomical observations?
Astronomical observations detect electromagnetic radiation from celestial objects.
What other key property of astronomical observations is mentioned?
Astronomical observations are conducted at a specific location and time.
What is a spectrograph and how is it used in astronomical observation?
A spectrograph is a technical instrument used in astronomical observation to analyze the spectrum of light emitted by celestial objects.
What is a CCD camera and how is it used in astronomical observation?
A CCD camera is a type of detector used in astronomical observation to capture images of celestial objects.
How does light pollution impact the view of the night sky?
It obliterates the view of the night sky by scattering and reflecting wasted light from the atmosphere.
Why are migratory birds affected by light pollution?
Migratory birds are disoriented by artificial light while flying at night, affecting their ability to navigate.
How does light pollution impact astronomical observations?
Light pollution degrades the quality of astronomical images due to scattering, absorption, refraction, and turbulent effects of the atmosphere.

What is the warning given regarding the use of this presentation?
It cannot be shown as a scientific source, cannot be sold, recorded without permission, used, reproduced, or turned into a commercial product.
What is one of the most important information to record in astronomical observations?
Time and location of observation
Why is the time and location of observation important for astronomical events?
It is used for precise reductions of astronomical events that change in time and location of observation.
What is the scientific goal of an astronomer?
To answer an open question
What is important for precise reductions in astronomical observations?
Specific instruments and their instrumental specifications (e.g. detector properties)
What is an observatory?
A place equipped with specific technical instruments for astronomical observation to observe celestial objects.
What are the different types of observatories mentioned in the text?
Ground-based, airborne, space-based, and underground-based observatories.
What is the Turkish National Observatory?
A ground-based observatory.
What is light pollution?
Unwanted or excessive artificial light that results in a reduction in night sky visibility due to "skyglow" upward-directed light emanating from poorly designed or directed lamps and security floodlights.
What is one important factor to consider when choosing a location for an astronomical observatory?
Altitude
What meteorological condition needs to be considered for good astronomical observation?
Cloudiness or clear sky counts
What atmospheric properties related to water vapor should be accounted for?
Absolute humidity and relative humidity
Besides humidity, what other atmospheric particles can affect astronomical observation?
Dust and aerosols
What type of pollution should be minimized at an observatory site?
Light pollution
What wind-related parameter is important for site selection?
Average wind speed (and direction)
What atmospheric condition directly affects image quality and must be less than 1 arcsecond?
Seeing
What phenomenon related to atmospheric turbulence needs to be profiled for adaptive optics?
Atmospheric turbulence
If an observatory has excellent 'seeing', what does that indicate about the atmosphere?
Steady atmospheric conditions
Why is it important to obtain turbulence profiles along height for an observatory?
For adaptive optics systems to correct distortions
