Yerks Observatory 40-inch Refractor Telescope?

[Vala]

I'm doing a project involving telescopes and part of it is to do with the Yerks observatoy telescope and I was wondering if someone could tell me what it is actually used for? And maybe links to some pictures that have been taken from it?

Well I can tell you that it is the largest refracting telescope built and also one of the last due to the fact of it being an almost obsolete technology since reflecting telescopes took over, due to them being cheaper to build and they do not suffer from chromatic aberration. I could go into further detail but somethings to look up for a good start are the differences between reflecting and refracting telescopes, and chromatic aberration.

I went there when I was young, some 40 years ago. It is a specacular scope and the building is wonderful. Lots of astronomical history there. A lot of pictures came from it. I am sure many could be found on line.
