Double stars
Visual double stars are among the easiest of all astronomical objects to observe. A well equipped observatory and large telescope is not required. There are thousands of visual double stars that are within the range of small telescopes. Double stars can also be observed easily from locations suffering from moderate light pollution.

Variable stars
Variable stars are stars that change brightness (most stars – including the Sun – vary in brightness if measured accurately). By studying their behaviour, much can be learnt about their physical properties such as size, mass, luminosity, temperature, structure, composition and evolution. This information can then be used to understand other stars.
