Nice presentation on the Yerkes Observatory.  I visited there when is was operating a few years ago.  Neat old technology.

So is she talking about a super Chromacor?  Why not?

I think she exaggerates a little about the color reduction of the second element of the air-space achromat...

My wife and I got to look at Mars through the antique 26" refractor on observatory hill at the University of Virginia about 50 years ago - just spectacular, although the seeing didn't rally support it (nor I guess could it). No canals. They used to do visitor nights once a year.

See https://www.cloudyni...kes/?p=12228217 for another discussion.  Saw that thread while passing through the area and took a tour of the facility.  Worth the side trip.

Interesting video.  I never considered that it was a doublet.

 

I had the pleasure to look through the 36 inch refractor at the Lick observatory here in California, about the time I was just starting into the backyard astronomy hobby.  It was aimed at the core of M13 at the time, and the blaze of light and color is still burned into my skull.  It's apparently a doublet as well.

I live relatively close by Yerkes, and would also often go to San Jose for work, where I discovered the beauty of Mt. Hamilton Road and Lick Observatory. Every time I'd go there, after visiting customers who were pretty close by, I'd take a ride up to see the 36". Very peaceful and scenic.

Yes, it is a very beautiful area. I go up to Mt. Hamilton often when the weather is nice. Its a great location for binoculars, with nice views of the south bay area. Although the 36 inch refractor is no longer used for research, you can just smell the history in the building.
