Small aperture (<1m, typically 20–50 cm) optical telescopes with adequate back-end instrumentation (e.g. photometer, CCD camera and CCD spectrograph) can be used for spreading the joy and excitement of observational astronomy among postgraduate and research students in colleges and universities. On the basis of our experience over a decade of observing with small optical telescopes it has been amply demonstrated that such a facility, which any university can hope to procure and maintain, can be effectively used for teaching and research. The Physics Department of Pt. Ravishankar Shukla University at Raipur, India offers Astronomy & Astrophysics as one of the specializations of its MSc program in Physics. A set of observational exercises has been incorporated with a view to provide training in observations, analysis and interpretation of astronomical data. Observing facilities available in the department include 8”–14” aperture telescopes equipped with a photometer, CCD camera and a CCD spectrograph. A facility of this kind is ideally suited for continuous monitoring of a variety of variable stars, and thus can provide valuable data for understanding the physics of stellar variability. This is especially true for a class of variable stars known as chromospherically active stars. The stars belonging to this class have variable light curves that change from year to year in a rather strange way. A large fraction of these active stars are bright; hence the importance of small aperture telescopes for collecting much-needed photometric data. For over a decade the research activity using the 14” optical telescope has focused on photometric monitoring of well known and suspected active stars. These data, together with X-ray and radio data from archives as well as spectroscopic data obtained at Indian observatories, has led to the identification of new chromosperically active stars. This paper is aimed at sharing our experiences with the colleagues from the developing world on the usage of small optical telescopes for teaching and research with the objective of spreading the joy of astronomy among young students.
