The CSO instrument features major technological advances in relation to Helios 2, including new visible and infrared band detectors, more highly integrated video electronics, new cooling mechanisms for the infrared channel and a new ceramic framework for the telescope. Compared with the instrument on Helios 2, the CSO instrument is 30% larger with twice as many parts for significantly higher resolution images, but development time was cut by 40%. CSO is considered the largest and most complex "space camera" ever developed in Europe.

Best resolution probably around 0.3 m
