i finally got an odyssey character into the system and FSS to generate the logfiles BodyID's. Including asteroids, barycentres and rings, there are 77 bodies in the system. unfortunately, its a layer G system , so only the first four bodies (two suns, a barycentre and an asteroid) are targetable by the overflow method. If there is a hidden spacestation here, it will be body 78. If anyone has any other ideas or suggestions, I'd appreciate your thoughts. cheers
