Yerkes is a wonderful place and instrument, but, there are lots of amateur astronomers with better equipment in there back yard than the scope there.
And most are in darker areas.
It should be preserved, but, unfortunately, it’s not good enough for useful science any more :(
.
Functional observatories these days are all “Adaptive Optics,” and in very high places.
I understand; but it’s so beautiful, and still useful for some educational outreach purposes. I hope they can find a way to preserve and keep it open. (It would make a great art gallery space!)
