You've read all you can about how various types of ADCs and DVMs work,
I
trust? Schemes intended for getting slower conversions at sub-ppm
resolution may be adaptable for different speed/accuracy regimes.


Just to go back to Dylan's original question for a moment, can anyone
recommend something that WOULD be a good step up from a Toucam for
Planetary imaging ?

I would like to be able to get higher resolution on the planets, given
all other things being equal.
Unfortunately, as I tried to say at the beginning, I don't think there is
much 'step up', for planetary work.
To get more resolution, increase the magnification....
Webcams, have represented a 'breakthrough' in planetary imaging, allowing
people from the most unlikely sites, to get very good planetary images,
that better in many cases, images taken with scopes/cameras costing dozens
of times more.

Best Wishes
