Known data:


Calculated data:
Required Earth telescope diameter for 10m resolution on Moon: 22.4 m
Required Earth telescope diameter for 1m resolution on Moon: 224 m
Required Earth telescope diameter for 1cm resolution on Moon: 22 km
Hubble arcsec/pixel: 0.08 and 0.04

Formulas:
ResolutionArcSec = 4.56/Diam_in (Dawe's criteria)
ResolutionArcSec = 116/Diam_mm
TargetMinimumDiam_km = DistanceKm * Math.tan(ResolutionRad)
LimitMagnitude = 16 + 5 * Math.log10(Diam_mm / 1000) (link)
Rad = deg * 3.14/180
Deg = Rad * 180/3.14
