Telescope designers to emulate

 Russell Porter Pencil Drawing of Palomar 200 inch - Before it was built

I found this wonderful page of Russell Porter’s telescope design drawings for a 200-inch – Palomar! The drawings, all pencil, are beautiful, and demonstrate features that any newfangled CAD software would die to be able to deliver.  This image is a sample, go to this link (http://www.weertman.com/bruce/porter/) for more.
