I was quite excited to open up the starshoot 4 and take some pictures of Jupiter high in the North last night. Unfortunately all I get is the same thing I had with my homemade Logitech camera setup, see the photo below, a white disc with poor resolution and little white dots for the moons.
I have the included "Webcam monitor" software and spent half an hour fiddling with gain, brightness, contrast etc etc, turning gamma up made the picture soft-focus and smoother but no hint of planetary features with any of this.
I am using a Bintel 200mm Newtonian and tried with and without a Barlow reducer, which made no difference.
Very frustrating, has anyone encountered this and overcome it?

edit: the picture below is a stack of 30 or so, but the original single shot photos were pretty much identical
