Calculated co-ordinates are wrong

[wafels]

The calculation of the position of planets in the FOV appears to be wrong when compared to their position as seen in the images. This probably because the code assumes that the observer is on the Earth, whereas the images do not assume this. The images have been rescaled so they look like they are at 1 AU for any time during the orbit. Therefore images are created with different assumptions compared to the co-ordinates. The assumptions on the distance and position of the observer from the Sun for both the co-ordinates and images need to match.

D'oh! Light travel time now included.
