The 61-inch (1.55 meter) for the U. S. Naval Observatory at Flagstaff, Arizona was the first large aperture complete telescope designed, manufactured and installed by Boller & Chivens as a joint venture with L&F Industries.
\nAfter that time, all telescopes with apertures up to 52-inch (91.32 meters) were assembled in a new Boller & Chivens assembly building at the South Pasadena plant.<\/p>\n

The 100″\u00a0Carnegie Institution of Washington will \u00a0be located at Las Campanas Observatory, Chile<\/div>\n
The telescope\u00a0is being assembled by Boller and Chivens personnel in a\u00a0telescope assembly pit at the L and F Industries\u00a0assembly building.<\/div>\n

In the foreground is Larry Steimle standing by the 100″ main double mirror\u00a0secondary\u00a0support system.<\/div>\n
The\u00a0main support ring ties the top\u00a0Serrurier trusses\u00a0together on the telescope tube assembly.<\/div>\n
<\/div>\n
Mounted inside between two bearings on the centerline of the main support ring, is an\u00a0inner support ring that can rotate 180 degrees.<\/div>\n
Plunger type pins on opposing sides assures that the inner ring when rotated will stop\u00a0exactly at 180 degrees.<\/div>\n
<\/div>\n
The inner ring\u00a0has an assembly containing two separate opposing secondary mirrors. This allows setting up two different observing\u00a0f\/stop observing ratios. Either one of the two different secondary mirrors\u00a0can quickly be optically positioned for different observing conditions.<\/div>\n","protected":false},"excerpt":{"rendered":"
