Can you give me also an indication of the costs and the transmission rate of the fire wire camera? Currently I shoot at 10 fps on Jupiter with out much image degradation, but it is still USB1.1 @ 12Mbit/s.
It would be nice to upgrade to 25 fps without bus compression.
Cheers,

Erwin,
The camera is a Unibrain fire-i mono camera, currently on the unibrain website they cost US$154. I modded mine with a simple alteration to the board so that the shutter is always open - i.e. at 25fps I get exposure times of 40ms. Normally the onboard controller has a max exposure time of 30ms, not long enough for my 10" mirror.
This camera has worked pretty well for me, but it has a few problems, and I'll be upgrading to something better in the near future so I don't know whether I should reccommend it to you or not... I've had mine for about 15 months, and I know that the newer fire-i cameras are better than my version, but you might want to hold off for a couple of months until I get to try out a new camera in case it's a lot better.
firewire is 400Mbit, so no image compression at all. I use a mono camera + filters, so I get full res in each colour and no hassles fiddling with colour balance etc in the camera.
