Completed my first rendezvous today while orbiting Eve (to rescue Bill and Bob, Jeb stayed behind to go down with his ship) without any mods. Anyway the best advice I guess I could give is patience, and a good understanding of orbital maneuvering. You can't just thrust towards your target because you'll affect your orbit on the other side of the planet and you'll move away faster than you can correct. You need to sync the orbits so you catch up to your target. Like mentioned above, lower orbit to speed up and higher to slow down. It can be very counter intuitive at times. If you're ahead of your target but your orbit is going to be lower than your targets orbit, you have to thrust away from it to allow it to catch up. Also, again as mentioned, RCS. You can't really do it without it. As for a step-by-step, this is as I understand it: 1. Align orbit planes. 2. Position your apoapsis in exactly the same place as your targets apoapsis (this is your rendezvous point). 3. Position your periapsis below your targets so you catch up and meet at your apoapsis (next to impossible to judge accurately by eye, maybe mechjeb helps) 4. When you catch up to your target at your apoapsis you make your periapsis identical to your targets (Assuming the rest went as planned this is the easy bit) However, information required to do this is missing or a pain to get for now. Hopefully that will change soon. In my experiance (I'm counting orbiter in this as I've only done this once in KSP) you need to match up your orbits so you get within 1km of your target and then use RCS to finish. I can't help with mechjeb or docking side of things, I'm waiting for it to be included as standard. Anyone more experienced please correct me if I'm wrong.
