Hello Jean-Pierre!

Even though I am the one (so far) that has been compiling and packaging 'libgphoto' and 'gphoto2' for Maemo (until someone else hopefully takes over the responsibility), I am personally not using 'gphoto2' on my N800 very much -- because it is so unreliable with my Nikon Coolpix cameras. Perhaps you will have better luck than me with it

I am also interested in the 'Papywizard' system, especially since it can be controlled on a Nokia internet tablet. I am personally waiting for good prices and availability of the Orion/Merlin GOTO mounts in Canada, as well as a cheap/easy wired (or wireless) connection to control it (bluetooth?). The last time I checked the project, it still looked 'tricky' and 'expensive'. It sounds like you want to try to *combine* the 'movement' control with gphoto2 via USB controls?
