Reading this report https://visao.as.arizona.edu/eyepiece/eyepiece-observing-with-magao/ is bound to make you insanely jealous!
Visual observation of the Apha Centauri system at the diffraction limit of a 6.5-metre telescope (with adaptive optics)! (Actually, I'm a bit surprised that a modern adaptive- optics large telescope actually has an eyepiece holder!)
The eyepiece had a very red filter installed, passing wavelengths longer than 685 nm. This means the sharpest details in the image were as small as 22 milli-arcseconds. We’re pretty sure that this is the highest angular resolution image ever formed on a human retina.
...
During the night, 9 people looked through the eyepiece. These astronomers are the inaugural members of an exclusive club: “L’Ordine degli Astronomi al Limite di Diffrazione” (The Order of Astronomers at the Limit of Diffraction).
