TRIPOL is a three-colour imaging camera operating simultaneously in Sloan g', r' and i' bands. It is a visiting instrument from Nagoya University that we are pleased to offer on the SAAO 0.75-m telescope from Quarter 4 of 2012.
The beam is split by two dichroics, then directed to three SBIG cameras via the fixed Sloan filters, resulting in three FITS images for each exposure (g', r' and i'). The instrument is operated from the command line, and interfaces with the TCS such that telescope positional information is written to the FITS headers. The telescope can be slewed automatically to objects in a catalogue file stored on the instrument PC, and pointing offsets can be applied from the command line (e.g. for dithering).
Further information on the operation of TRIPOL can be found in the preliminary Users' Guide. Please direct queries to nagayama(at)z.phys.nagoya-u.ac.jp
