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.



The Lumenera LU075 as Pete mentioned near the top of the thread allows
faster frame rates (What Damian Peach is using these days)

Interesting - but £750. And still only 640 x 480 pixels

Number of pixels does not matter much for panets. Even at 0.1arcsc/pixel
(higher resolution than you are ever going to get from the ground) planets
are are going to be less than 480 pixels diameter.

To get higher resolution, use optimum magnifiction (say around
0.25arcsec/pixel, but open to debate) get a bigger aperture so you can take
more, shorter exposures, and a camera that can support them, move to the top
of a mountain ;-)


There have been some tests published on QCUIAG which suggest that the
USB2.0
1.3Mpixel Logitech Fusion webcam can match and possibly improve on the
performance of the Toucam Pro despite being CMOS technology

Very interesting - and at £50, probably worth a try. 1280 x 960

Probably best to look at Steve Chambers report first
