It is simple.
1. Choose a position where the proportional sizes of the Earth, Moon and Mars are what they are on the page. This is likely far away above the ecliptic (the plane the planets are in).
2. Choose a telescope focal length to set the right scale for the planets. Ie magnification.
3. Pan and imagine there is an object in the ecliptic plane at the center of your field of view. Mention the calculated speed of the object.
This all results in a moving star field.
