At a good site, on a high mountain with low turbulence, the seeing is typically between 0.5 and one arcsecond, meaning that any telescope will be limited to this range of resolution. Adaptive Optics Branches Out 2021-04-30T04:00:00Z

To put that into perspective, a microarcsecond is a millionth of an arcsecond. How To Build An Earth-Size Telescope 2014-04-11T16:00:23Z

But these are small angles, typically just fractions of an arcsecond. Gaia: The 'impossible space mission' ready to fly 2013-08-21T22:35:24Z

The second catalog contains information for more than a million stars, whose positions have been measured to thirty-thousandths of an arcsecond. Astronomy 2016-10-13T00:00:00Z

To give you a sense of just how tiny, we might note that 1 arcsecond is how big a quarter would look when seen from a distance of 5 kilometers. Astronomy 2016-10-13T00:00:00Z

The best images obtained from the ground with traditional techniques reveal details as small as several tenths of an arcsecond across. Astronomy 2016-10-13T00:00:00Z
