Our primary focus is on time series with related images. Spectral data and catalogues of derived parameters will also be included. Observations with small and medium-sized telescopes remain meaningful in the era of large surveys and major facilities. Such instruments are widely distributed, and their relatively low operational cost allows long-term high-cadence monitoring of individual variable stars. This makes it possible to detect subtle features, transits, and even evolutionary processes.
