Whereas ground-based optical telescopes have sub-arcsecond ** resolution, and Hubble is quoted as having a resolution of 0.085 arcseconds, single-dish radio telescopes can only get resolutions of a few arcminutes.
First Stellar Images Nicole 2009
The Very Long Baseline Array, stretching from Hawaii to the Caribbean, regularly produces images with milli-arcsecond resolution.

In astronomy, the preferred unit of measurement for such distances is the parsec, which is defined as the distance at which an object will appear to move one arcsecond of parallax when the observer moves one astronomical unit perpendicular to the line of sight to the observer.

To image something green on the sky to 1 arcsecond (which optical telescopes routinely do) thus requires a telescope of size at least 10 cm.
Two Trinities daniel 2007
Quite nice, with image/elevation data of the world down to 1 arcsecond .
GISS Interruptus « Climate Audit 2007
The parsec in turn is defined to be a certain multiple of the astronomical unit original such that the parallax of a star as it appears from the Earth is 1 arcsecond .
