Your guide isn’t very useful. Next time (which there shouldn’t be, because “guides” aren’t your strong suit), at least add some description that goes along with your marks on the map. I’m at one of your points and don’t see anything.
Which one are you having trouble with? I have followed this guide, so far to Corellia, and have not had a issue with finding the droids. Silly question are you using the binocs, and scanning up and down?
