But still, guesstimation :pE.B.

You want your median burn time to rest on the node. So if it's a 2 minute burn, burn one minute before the node and one minute after. Also if possible always burn on the apoapsis or periapsis, you'll get the most efficient delta v to fuel burned ratio at those points.Stormweaver wrote:
But seriously, this run has taught me a lot - how to get into a easy polar orbit around the Mun, how to not waste the last few drops of fuel in your orbiting stage before going to the Mun without having to guessimate when to start burning.....
I'm gotten into the habit of seeing how much fuel I have left, setting up a node that will more or less use all the fuel, then setting up another node in the same place (well, a little behind, but on the new orbit) for the actual burn with the little engines. Then you just have to tweak a little to get it in the right place. I don't know how useful it actually is, or whether I'm just using it as a crutch for my utter lack of skills in flying, but I'm going from having a slither of fuel left once in Mun orbit to often having over half a large tank. Which is literally the difference between burning up or re-entering.
