How to get to Gilly

Gilly seems like a particularly hard moon to get to, since it's on an inclined, eccentric orbit and has a very small SOI. But here is an easy efficient way to get to it.

The most important insight I found was to line up the periapsis of the incoming trajectory with the plane of Gilly's orbit. This means that the apoapsis after capture is also on the same plane, which means the plane change maneuver can be performed near apoapsis, greatly lowering the delta-v required.

This technique should work for any moon, particularly when you're coming into a planet's SOI at a high inclination with respect to the moon's orbit (like Bop for example).
