Details:
In this collage of the Solar System the angular dimensions of the planets are all in scale (as seen from Earth), and also the distances between the planets are in scale.
From May to November 2020, all the images of the different planets have been taken with a Celestron NexStar 127 SLT and a ZWO ASI 120 MC-S (and a safe Solar filter for the Sun).
I supposed each orbit to be a circle, so that seen in perspective it appears as an ellipse: even if vertical distances are compressed, the scale is respected. The semi-major axes of the ellipses (where the center of the ellipses coincides with the left edge of the Sun) are in the same proportion of the real semi-major axes of the planets' orbits.
In the right top of the images I inserted both the scales, one for planets distances and the other one for planets apparent sizes, to better understand the image.
