Al Paslow, and my 10 inch f-20 primary mirror for a Buchroeder reflecting Schiefspigler Telescope. I broke this mirror in the early 70's while attemping to remove a small central zone during "hot pressing" the mirror on the pitch lap. I slipped on some water on the floor and broke a section from the mirror trying to place a heavy weight on to the combination. I made this mirror shortly after this particular design was sent to me directly from Richard Buchroeder, in 1971. It was a modification of the design which appeared in Sky & Telescope Dec 1969. The modification was called O'Neil- Buchroeder Schiefspiegler" and no one had compleated an instrument of this type. This mirror might well have been the first.
