I started playing RSS w/RP-1 four days ago and just achieved orbit today, I'm still struggling how to properly launch on the plane of the Moon, same for the Lunar Transfer Window Planner mod included in the RP-1, I don't understand how it works. I've just been launching my rockets at random times since I don't need to go to the moon yet, but I want to learn and understand doing gravity turns and using the Lunar Transfer Window Planner for future missions. My question is at what angle on the navball should I launch rockets so that there's a little to no difference on the orbital inclination of my craft and the moon?
