Should this be considered within/part of the Mount Kent Observatory complex?

https://www.unisq.edu.au/study/why-unisq/unisq-stories/research-stories/smartnet seems to suggest so, in which case we should extend https://www.openstreetmap.org/way/516925285 to cover this site and then also tag man_made=observatory on that way.

Then this way could be tagged man_made=telescope + telescope:type=optical would that be a better fit?

What do you think?
