Activities with Goto 45-CM Reflector at Bosscha Observatory, Lembang, Indonesia: Results and Aspects for Future Development
In 1989 a 45-cm telescope of a cassegrainian type was installed, tested and commissioned at the Bosscha Observatory, Institut Teknologi Bandung. It was immediately put into use for UBV photometric observations of close binary systems. While the main function of the telescope was for photometric observations, the versatile design inherent to a reflector made possible to include a spectrograph which spectral dispersion could match the MK spectral classification. Activities related both to education and research conducted using this reflector since its installation comprise of scientific (photometry, spectroscopy, imagery) and experiment in instrumentation (fiber-fed spectrograph, CCD camera insitu testing). An important side result of the photometric observations is atmospheric study based on long-term atmospheric extionction coefficients. A multidiscipline approach, involving meteorologist and mathematiciants, on the study of natural and antrophogenic pollution of the atmosphere over Lembang has been recently undertaken. At present the telescope is, however, suffered from obsolete technology in its control functions. This has hampered it to be utilized fully, and therefore a plan to upgrade and extend the capability of the telescope has been made. The background, activities and results with emphasize to the collaborative work will be presented. Aspects for future development of the telescope and its auxiliary instruments will be discussed.
