The 36-cm Schmidt-Cassegrain and CCD
The University of Ljubljana 36-cm, f/11 Schmidt-Cassegrain telescope is fully computerized and equipped with the 574x385 thinned CCD, manufactured by Wright Instruments Ltd. An additional telecompressor yields the f/6.8 ratio and is very useful for observations of extended objects. A 10-cm, f/10 guiding telescope is mounted piggyback and attached with the ST-4 CCD autoguider.
The telescope will be available for the participants of Astronomy On-Line project during the hot phase.
The 36-cm telescope is most suitable for
| - standard BVRI stellar photometry |
| - imaging of faint comets |
| - imaging of deep-sky objects |
