A great thank for everyone who helped me! especially:
Chris Peterson for sharing his experience and his
precious technicals advices, and to have patiently answered all my novice questions. A major part of my all-sky camera is based on his own.
Sébastien Morin who encouraged me in this project and helped me to develop the "computer" system.
Matthew Schilling, with his international network I was able to make this project cheaply, without forgetting the small ... screw..
Tim and Pat Becker, UPS international competitor ;-), who allowed me to receive my camera and the objective at a lower shipping price.
My grandparents who haven't hesitated to make holes in their house to get the cables through and install the camera.
And of course my Katalin who supported me during this time and without whom I couldn't have done all of this.
