In the absence of an entry for the individual world quest I encountered (neither the wowhead search nor google can find it, as it appears),
this seems the best place for it:
Technoscrying: The Mysteries of the Concord Observatory
Some folks are talking about issues with the quest, but I didn't experience them, in the thread (official forum) HERE.
Landing in the area, I was able to immediately get started.
Zenata appeared to be marked, but didn't offer anything to me (my Technoscryers were in my bag).
She's meant to offer you another pair of goggles / Technoscryers, if something happened to yours.
She won't, if you have them somewhere (like your bank), according to the thread (official forum) HERE.
A War Mode switch was not needed for me. I was in a standard PvE setting, with War Mode off, and everything was fine.
Equip the Technoscryers in your bag, click the button to scry and get started.
Positions approximate / close (with Technoscryers used and scrying started):
