Released as a special product for International Year of Astronomy 2009, the Galileoscope was designed by scientists and educators to provide a near replica of the 'scope that Galileo turned on the heavens 400 years ago. One of the design features is a very reasonable quality 2" objective lens. To get an idea of the quality possible from this cheap 'scope, I attached a Philips Toucam 740 webcam and started filming. This video is speeded up 2.5x to make a 25fps video from the original 10fps capture, and is upscaled to 720p to keep as much quality as possible on YouTube. The 'scope was fixed in place - the movement of the Moon is due to the Earth's rotation
@riquelegau Hi there! Neither in fact - the 500mm focal length of the Galileoscope combined with the small size of the imaging chip in the Philips Toucam - approximately 6mm across the diagonal - gives about 85x magnification - enough that the whole Moon won't fit in the image!
Clear skies,
Paul.

Did you used zoom of the camera or the barlow lens?
