A variety of techniques can be used in variable star observing and the following guides are provided to assist you in refining the use of them.
The VSS guide “How to Observe Variable Stars” is the essential short introduction for visual observers using binoculars or telescopes. This begins at the beginning, and covers techniques, charts, and recording and observing, as well as some handy hints about pitfalls.
Variable stars change brightness; slowly and ponderously, rapidly or explosively, or anywhere in between. The phenomena relate to much, maybe even most, of stellar research, and professional astronomers rely to a large degree on amateur observers. The observation of such stars is the easiest way for the amateur to cooperate and interact with professional astronomers.
