This composite image of Saturn has been obtained with a Philips Toucam pro 740 webcam
on the C11 + Barlow lens (ca. 6000 mm focal length).
For the above composite, 4000 individual images (almost 4 GB!) have been recorded with the webcam, the 1000 best images selected, enlarged, stacked,
sharpened and contrast-adjusted with the Giotto astro-video program.
Here is a single image obtained with the webcam:
The composite after enlarging and stacking of 1000 of such images:
The stacked image still appears blurred, however it has a very high signal-noise
ratio and rather severe sharpening algorithms can be used.
The sharpened image:
After adjusting contrast and color saturation, the final image (above) is obtained.
