    how i can determine the temperature at the focal point and power

    Excellent idea! I wonder how painting on a fine coating of acrylic would work to make the mirror a bit more 'permanent.'

    The mylar has a first surface side and a second surface side. The aluminum deposition or the shinier side should go inside. This exposes the mylar to the elements and the aluminum coating to the interior. This is the big one that explains all about the process.
