Allegheny Observatory - Machine Shop etc.

This hand drawn image & also the one on of Jupiter is of great interest to me. it is an original & was sketched by James Keeler on Jan 7, 1888 while using the 36 inch refractor at Mt Hamilton in California. Keeler of course was a Director at Allegheny Observatory, and was the first person to discover the rings of Saturn were made from particles, and was not a solid. The sketch was made while Keeler was at Lick Observatory, and was brought to Allegheny. They have since been remounted and a more modern frame added to enhance the beauty of Keeler's artwork - Information verified by Art Glasser - Sept 2009.

This is another Keeler sketch which at the eyepice of the 36 inch refractor at Lick Observatory. It is dated July 10, 1889 and signed J E Keeler.

Largest lathe in the shop. Perhaps 18 inches swing. I could not find a name or brand but it has the old overhead belt drive that dated the machine.
