TCP

 

The TCP camera (Tromsoe CCD Photometer) is a portable instrument optimized for fast readout photometry (Windowed system) based on CCD technology. TCP incorporates the possibility of an on-line data reduction, i.e. that light-curves of the targets can be produced in real time, so that the observer can investigate the results as they arrive. This instrument was built at the Physics Department of the Tromsoe University (Norway), in a collaboration with the CUO (Copenhagen University Observatory).

Below we show the light curve of the pulsating star RV Ari (magnitude ~12), in blue, with 19-second time resolution and ~0.2% error, with a fainter comparison star, in red. It was obtained with the TCP at the IAC80 telescope.
