AFAIK, the guy shot one exposure to get the foreground. The rest of the exposures, of the sun. were done with a solar filter, small f-stop and fast shutter, so the light from the foreground scenery as insufficient to exposure the film.
Other than that no manipulation was done.
That sounds reasonable. The sun is so very, very bright that in order to get a good exposure of its disc, everything else in the frame becomes totally black.
Speaking of which, has anybody a recommendation on solar filters? I have a aluminized mylar filter that I have used to shoot a couple of solar eclipses, but it makes the colours strange:
