FAQ
Frequently Asked Questions
No. Astrophotography is about capturing images of celestial objects. Astrophotometry is the scientific measurement of the brightness or intensity of light from those objects, often using the images from astrophotography.
Primarily telescopes equipped with photometers or specialised astronomical cameras (like CCDs) and filters that isolate specific wavelengths of light. Software for precise data analysis is also crucial.
It allows astronomers to determine fundamental properties of celestial objects, such as their temperature, distance, size, and composition, by analysing how much light they emit and how that light varies.
Yes, with modern digital cameras and software, amateurs can perform basic photometric measurements, such as monitoring the brightness changes of variable stars or exoplanet transits.
