The study of variable stars and exoplanets is one of the most significant areas of contemporary astronomy. A vast amount of new information and as-yet unexplored systems offer amateur astronomers a unique opportunity to actively participate in research. High-quality instrumentation, now accessible even to amateurs, and publicly available astronomical survey databases directly encourage the discovery of new insights into exoplanets and interesting stellar systems.

If you are also fascinated by the night sky and wish to contribute to uncovering its secrets, become a member of the Variable Star and Exoplanet Section of the Czech Astronomical Society (hereinafter VSE Section of the CAS) and join the work alongside professionals and other enthusiastic observers. You will become part of a friendly community of people with a shared interest who will help you get involved in the research of exoplanet candidates, pulsating and eclipsing variable stars, and other fascinating areas of space exploration.

Members of the VSE Section (Variable Star and Exoplanet Section) are also granted access to the ROST robotic telescope in Ondřejov and have the opportunity to borrow observational equipment (CCD/CMOS cameras, observation setups).
