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....

Fair enough. In which case I need a higher power Barlow.

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.

Absolutely - I'm still blown away with what can be done with a £50 camera
and am nowhere near reaching the limits of it. I was just interested in
whether or not there was anything out there with higher resolution. Of
course, more pixels for the same image size means smaller pixels which in
turn means less photons per pixel, which means more noise....
