Oh my goodness. That is the cutest black hole in here. And he’s comin’ this way, oooooooooooooooooh!

Are the tracking systems for those massive telescopes sophisticated enough to track objects by designation, or do they still require coordinates? Like I know they have tracking for earths rotation but I can’t even imagine needing to look up the info to set sights on some body for the allotted view time, however many days that would be done for (I assume it’s a set of long precise numbers, far too long to easily memorize)
