In fact, imaging Jupiter requires a very good seeing due to longer exposures and limited contrast of the Jovian astmospheric marks. One must target steady conditions while the planet is as high as possible in the sky in order to have some chances to get satisfactory results. Once again, the observer somewhere around the equator or generally speaking at lower lattitutes will be previleged. Jupiter's displays a wide range of subtle colors only visible at the eyepiece with somehow large apertures and good seeing. Getting true color images of Jupiter is made difficult with the ST6 given the limited downloading rate of the camera and rapid rotation of the planet.
Frames are hard to assemble as the planet has always rotated while imaging the various colors.
Results obtained when the planet was still high in 93 are reported at the following page The magic world of Jupiter and also include the frames obtained during the collision of SL9. Saturn Imaging Saturn photographically is a nightmare and the results are too often frustrating. The CCD makes it so easy that one wonders whether it is the same object. In fact, I would recommend to keep exposures reasonably short even though this might somehow limit a bit the dynamic of the images. True color imaging is also possible even though Saturn is all but remarkable for its colors.
