WebOnce wealth measure color using photometric techniques, the camera integrates all the light that each filter transmits. For each measured star, this sum gives us the star's brightness in that filter, so ours reduce all transmitted light to a single number. Then, with comparing it to the brightness in another filter, we get and star's color index. Web仙王座PV（PV Cep）. 仙王座PV是位於 久布達基安星雲 （英语：Gyulbudaghian’s nebula） 邊緣的亮點。.
