what i do when taking images of Jupiter with my DSI is uncheck the box next to the shadow enhance, and then click auto exposure, as the program starts to figure out the correct exposure, you'll see jupiter appering, just stop the progress and manually bump it up or down, until you dont get any over exposure on the image, only issue i have with doing it like that, is i cant get the moons to show up in the image, hope this helps
