It was single point aligned with a 128 pixel box around the planet disk and I'm pretty sure it's not a processing artefect - like I said the centre of the image on each of the avi frames is pretty much a white 'blob' which I assume is what is meant by saturated. The 'right brightness' on the screen is exactly my issue - my first set I could just see the main bands against the disk and figured that stacking would bring out detail (which it did to some extent) but the verdict was 'underexposed'. With this one it just looked like a white blob on the screen and I thought 'that can't be right', but the meter was at 200 as recommended so I went ahead.
Now I'm just really confused.... What should I be seeing on the screen when the exposure is 'right'?
BTW, does the fact that I'm got the older 740K ToUcam (the egg-shaped one) make any difference? Can't see how but it's just a thought.
