He can clearly see the roof of the imperial facility. With the macro's, you can clearly see the gun crews and what look like observation droids stationed on the roof. You have clear shots to all four anti-personnel cannons, and the uplink is also clearly visible.
Doing a scan, Trax spots on a nearby building what appears to be an Imperial probe droid. It looks inert however, having clamped itself to the roof of the building. It's sensors are facing your intended target. Continuing the sweep, there is another probe droid in another nearby building, in a similar stationary configuration. Finally coming to the debris pile, Trax can make out through sightlines in the debris, the upper shell of a similar droid. Judging from the positions around the Imperial facility, the Empire has placed droids to watch the approaches to the base. The others were inert, but the movement you saw suggests you may have activated the droid on this building, but there is no indication it has seen you yet.
You droid is about a hundred meters away, on the far side of a debris pile.
