Description

I had a lot of trouble trying to set the proper exposure to see anything on Jupiter (what I have to do is use Windows XP under VMWare and run Craterlet. When capture starts, I have to open the camera control and set the exposure (around 50 ms for Jupiter) manually. When capture finishes, it resets to some badly overexposed value. I haven’t found a better work-around). This image was exposed a little more than most I took tonight (105 ms). Io is to the upper right, just prior to beginning transit
