I'm sure they were aware of that problem, and probably had a SRS geared to the Dec system.

"Mr Einstein is such a charming man. He has assured me that our wonderful new telescope is not sagging,

" I have to admit, Mr Einstein, that finding a target with this instrument is very challenging.

The setting circles on these modern telescopes are so small, they're just ornaments really."   😀

Good point actually, the setting circles are as impressive as the rest of the scope.

I heard things are not looking so good for the Yerkes 40" scope and it may be mothballed.
