For example, there are the Magellanic Clouds, various southern hemisphere galaxies and some of the brightest star clouds. Myriads of stellar jewels shine in the Southern skies!

Photometry measures the intensity or quantity of light received by means of different colored filters. This system can be used to determine the temperature, brightness and distance of the object being studied.

It is evident, then, that the telescope does the seeing and recording and the astronomer does the analyzing. One astronomer told us that the organizing and analysis time may be more than four times as much as the actual observing time with the telescope. His analysis time may involve a comparison of his photographs with others of the same celestial region taken years or decades ago, thus revealing the relative movement of the stars, changes in brilliance, and the appearance of new stars.
