PPT-Photometry : The measurement of the intensity, brightness, or other properties of light.

Photonssec Count Photons Sounds simple but what if the measuring equipment misses some because it is not 100 efficient what if the atmosphere or telescope dont transmit all of the photons.

Candela.. “Great, but what is a Lumen?” . we . hear you ask.. The lumen can be thought of as a measure of the total "amount" of visible light in some defined beam or angle, or emitted from some source. For example: Consider a candle giving off light:. USNO-B1 1289-0181948. Blake Head. What is a Variable Star?. A variable star is simply a star that changes in brightness over a set period of time (generally). This can happen in eclipsing binaries, where a star passes in front of another companion star, and pulsating variables, in which a star physically pulsates inwards and out due to instabilities within its core. .
