Which one cant do in ingame galnet, which further reinforces the point about ED being more of a browser-forum game...
Anyhow, not sure if it has been mentioned, but when viewed from the "bottom" of the galaxy (i.e. when when putting camera under galactic plane and looking up), new systems roughly repeat pattern of monolith locations in our known ruins (please note, that it was not my intent to align map screenshot perfectly, but rather to roughly illustrate my observation)
Assuming for a moment that these line up with tower relics, that would be incredibly obscure, the galaxy map can be viewed in a 360 sphere, was/is there a reference at the site that might indicate the angle to view galaxy from? if not, then the positioning of the tower relics become meaningless.
