The Starfire project provided much of the funding for a new polishing lab built in 1990 and equipped with an 8 m grinding and polishing machine and a 24 m test tower which were first used to figure the 3.5 m mirrors.

The surface is rather bumpy and to remove these irregularities it took me a 2 hours or so using a MOM mirror-O-matic and carbo 120.
