This definitely helped me a lot! Thanks so much!
I just ordered the belkin wifi card together with a vimicro camera.
I think the camera will be excellent -- considering it has mechanical interface, so maybe I can experiment combine it with a stepper motor to provide software controlled telescope...
 
low price high quality. oh yeah.
Thanks again.
