ok, so you have mastered the difficult part of achieving orbit. there are two ways of getting to the mun 1. watch kerban as you orbit around it.. when you see the mun rising over the horizon then initiate a prograde burn, switch to the map view and wait for your encounter with the mun. 2. spin the map view until the mun is at the 12 o'clock position. then create a maneuver node at 5 o'clock position and add prograde (this is essentially the first method except youre using a maneuver node). Continue to add prograde juice until your orbit touches the muns orbit. If you don't get an encounter with the mun... no worries. just grab the center of the node and slide it around on your orbit until you get one! once you get an encounter just warp to the Pe you will get from the mun and burn retrograde until you get a capture orbit. I hope this helped!
