Newtonian primary mirror
A Newtonian primary mirror made of glass in a box. The mirror is in its original iron cell with a narrow brass retaining rim and a close-fitting tin cover. It is transparent and is mounted on velvet. It was not removed from its cell. The general figure of the mirror is very even, except for a small central spot of long focus, surrounded by a narrow zone of short focus of radius 1 inch and a narrow zone of short focus about 1 inch from outer edge.
