A minute of arc [See Link] or arcminute (MOA) is a unit of angular measurement, equal to one sixtieth (1/60) of one degree. Since one degree is defined as one three hundred sixtieth (1/360) of a circle, 1 minute of arc is 1/21,600 of the amount of arc in a closed circle.
There are 148,510,800 square arcminutes in a complete sphere.
A circle is 360 degrees.
A degree is a circle divided into 60 equal parts.
An arcsec is a degree divided into 60 equal parts.

An arc-second is equivalent to one sixtieth (1/60) of one arc-minute. An arc-minute is equivalent to one sixtieth (1/60) of one degree.
What is 0.01 arcsecond?
0.01 arc second is one hundredth of an arc-second.An arc-second is one sixtieth of an arc-minute. (There are about 30 arc-seconds across the visible diameter of the Sun or Moon).An arc-minute is one sixtieth of a degree.A degree is one three hundred and sixtieth of a circle.So a hundredth of an arc-second is a good resolution for a fine telescope.If you have an image of the Moon where the moon is 3000 pixels wide (probably twice the width of your computer screen) then 0.01 arc-second is one pixel.
Can the unaided eye resolve a crater on the moon whose angular diameter is 1 arc minute times 60 arc seconds. Take the pupil diameter to be 5 millimeters and the wavelength........?
I can resolve 100 arc seconds. If craters are 60 arc seconds I'd bet that there are people whose eyes are good enough. 60 arc seconds is certainly within the 20 arc second maximum capability of the eye.
