I thought Mars was a lot bigger. Doesn't look big enough for a Musk colony.

It's a composite. Physics cannot get both in focus at those distances.

While it's true that only one plane can be in focus, depth of field grows with distance from the lens. 'Physics' absolutely can get both 1/2

in focus at the same time. Indeed, many small aperture devices have such an enormous depth of field (often something like 15cm to 2/3

infinity is not uncommon on phone cameras) that the ability to adjust focus is omitted altogether. Any claim about depth of field is 3/4

machine specific, *not* a claim of physics. 4/4

Aren't most photos of things in space composites?

'Most' would probably require qualifying a lot of other words in that sentence, but essentially all professional or serious amateur 1/2

images of celestial objects are composites. 2/2
