Presumably you meant to say 14 miles, not 14 feet. Also, since the adaptive optic system acts on the near-IR light, let's shift the 500nm used to calculate the Rayleigh criterion to at least 1 micron, which doubles the limiting resolution to around 0.011 arcsec.

Close, 16 mas in R: https://sites.google.com/inaf.it/shark-vis/home

The Rayleigh criterion gives a limiting resolution assuming monochromatic light. The quoted 16 mas is a demonstrated resolution for a broadband filter. So, I was ballparking things and they have achieved an awesome result for a relatively short wavelength! That resolution is just achieved for the inner 1 arcsec of the image, though.

Yes, sorry, 14 miles (a wishful typo!)
