Thanks for the info Malclom, much appreciated

the Camera uses a CCD sensor but as you mentioned, under Video mode , i have no control over ISO or exposure unfortunately.
As for more frames, i know that the features on Jupiter rotate every 90 seconds. So my question is do we have to capture as much frames as possible during the 90s seconds or is there another way of doing things to get more frames ?
