I published a Topic before but it was a bit complex for someone starting out . I have shortened the formulas I used . And made the Images into Masks so they can be used in several ways including filters as in the example test .
Notice I put the main formula in the X position Field that gives us the opportunity to tweak the Opacity
The Formula in Rotation is to make the Moon correct for the Southern Hemisphere .
$#LAT#>0?0:180$
I have made this a WiKi so it can stay live forever .

Images start at 0 = NEW MOON
