Techniques used in variable star research

Participants in the VSS community undertake research using a variety of techniques. You can learn more about these techniques below.

Video photometry

Video cameras have been traditionally used for photometry of lunar and asteroidal occultations and mutual events of planet satellites. Since recently they are also being used for identifying the times of minima of short periodic variable stars. Those cameras provide a cost-effective option for variable star research as well as an opportunity for typical occultation observers to also contribute to variable stars science.
