Datatype: UBVCam
The UBV system has been adapted to the use of electronographic
cameras and filters. However this technique did not develop very much
due to the difficulty of operating the electronographic cameras and is
now replaced by the CCDs . A few clusters have been observed with this
kind of instrument.
