I poked the numbers above into a Rayleigh criterion calculator and got a number measured in thousands of light years? My comment on if my math was correct was prescient. 10^-25 showing up should have been a hint to myself, whoops.
(The calculated horizontal resolution required for a 2 pixel wide star from the original post should instead be 100,009,624)
The corrected number for star apparent diameter should be 0.006983 arcsec. Depending on how finely you want to resolve the disk, that would take somewhere between a 70 to 140m wide telescope. (With 400nm light)

The largest optical telescope currently under construction is 39.3m wide: https://en.wikipedia.org/wiki/Extremely_Large_Telescope
