> The EHT images are created using synthetic aperture techniques to create an effective aperture with a diameter of earth's orbit around the sun.

Small correction: The EHT is a synthetic aperture telescope the size of the Earth, not the size of the Earth’s orbit around the Sun.

Synthetic aperture telescopes need both amplitude & phase information from each observing station & have to combine the phase of simultaneous observations in order to create the final image. We can’t do this on the scale of the earth’s orbit, because we don’t have a radio telescope on the far side of the sun!

Maybe one day ...
