The objects were compared to an asteroid database and were later found to be known asteroids. The coordinate system of the sky - right ascension and declination. The brightness scale of the stars - magnitude. The size of the images are measured. Speed of the motion of the objects is measured.
Retrograde motion is shown on some of the images.
The creation of digital images of the night sky with CCD cameras is explored. Locating Internet sites from URLs. Converting images from one format to another. Digital image processing - animation, aligning, measuring, enhancing, false color, etc. Saving and opening files.
