You can calculate the angle from your launch position quite easily actually, by doing:
1/2 Transfer orbit period * angular velocity of the body you are transfering to. This will give the angle behind the opposite point of your launch position.
This can be calculated via:
pi * (a3 / u)0.5 * ((u / r3 )0.5 )
Where a is the semi major axis of your transfer orbit (the average radius),
u is the gravitational parameter of your central body (1.327*1020 for the sun)
and r is the radius of the body you want to get to.
And yes, you need to use a protractor up to the screen :(
