I am admittedly a fairly new player of ED: Horizons and have opted to use trading as my main source of income. I have been struggling with locating specific markets though; for example, the galaxy map says that in the Llyr system, there are markets such as the Malecela Command Site and the Casari Hydroponics Hub, but I cannot route directly to them and they do not show up on the External Panel's Navigation page or the system map. How do I find these and visit them? They often have really good trade prices, but I can never make use of them.
