WebNov 24, 2008 · sequence stars on top of your apparent magnitude H-R diagram, you will be able to relate the apparent magnitude (m) of a cluster star to an absolute magnitude (M) from the main sequence plot. Knowing the apparent and absolute magnitude of a star, you can determine its distance (in parsecs) from the equation: D = 10 x 10( m –M ) / 5 (1) WebPhotometry and CCDs. Photometry 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 the CCD until it is read out. The more photons hit a certain pixel, the more ...
