Just for refference guys.
Gleeecooo: in you picture. The orange moon represents where the the moon WILL be once you enter the orange line.
Also when your turning around 180Degrees, look for a green arrow with the lines at funny angles (On nav ball) the is optimal decent vector.
Youtube is your friend too learn quickly. (But trial an error is more fun)
Also land slower than 2m/s an with no lateral drift, or it'll break up.
I personally find using uptimal desent vector, until 100 meters at 5/10m/s.
Then engage ASAS with the nose pointed straight up, us main thrusters to reduce speed to 1-2m/s an Translation RCS to stop all lateral drift.
Greatly simplifies landing work load, only have 2 Dimensions to manage, rather than 4 normally.
Easy as crashed Kerbal pie.
