Photometry (astronomy) - Wikipedia
WEBIn astronomy, photometry, from Greek photo-("light") and -metry ("measure"), is a technique used in astronomy that is concerned with measuring the flux or intensity of light radiated by astronomical objects. [1]
WEBThis AAVSO Guide to CCD/CMOS Photometry with Monochrome Cameras has existed in a number of different forms, including The AAVSO Guide to CCD Photometry , since AAVSO observers first began using CCD 1 cameras in the 1990s.
Introduction to Photometry - Las Cumbres Observatory
WEBPhotometry is a technique that measures the brightness of a star in an image. Each pixel on a CCD will have had a certain number of photons fall on it during an exposure. This number of photons translates to a number of electrons that are stored in …
