First Philips 900nc photos - can it be better?

Hi,

I've finally got my Philips 900nc webcam working. The first one sent to me from a seller in Canada did not work. It would be detected by the system but the drivers could not be installed (even if attempted manually). Finally, the seller was good enough to send another.

On the weekend I tried imaging Jupiter using K3CCD. I have a 6 inch GSO reflector and used a 5x GSO apo barlow. The image without a barlow, or my 3x barlow was just too small.

The results:

Stacked image:

Movie used to create it. Not much detail visible and a fair amount of boiling and fringing:

Apart from the seeing conditions being less than ideal, how much more detail can I expect to see?

How is magnification calculated for my 150mm F5 reflector with 5x barlow?

It was not possible to focus the image more sharply. Jupiter was about 45 degrees in the sky but I didn't want to wait to 5am.

The GSO 5x apo barlow is fine but there's still a lot of false colour in the image. Would buying a Televue barlow, or a powermate improve the image substantially? I don't want to waste a lot of money needlessly, seeing as this is only a 6 inch scope.

Thanks,
