The siderostat is a single flat mirror mounted in front of the objective which directs
the beam of the telescope to the desired position in the sky. The mirror itself may
be either equatorially mounted or driven at varying alt-az rates, in which case it ...

Case Studies in Reliability and Maintenance
The state of each of the four kite triangles is modeled as a column of cells which
align with the representation of operating siderostat bays discussed later. The
collection of SBBLs is modeled as a matrix of cells, with a column corresponding
to ...

Astronomical Observations: Astronomy and the Study of Deep Space
The siderostat is any of a class of astronomical instruments consisting of a flat
mirror that is turned slowly by a motor to reflect a given region of the sky
continuously into a fixed telescope. In the traditional siderostat, the mirror is
rotated by a ...

An Introduction to Optical Stellar Interferometry
Pointing to the star can be accomplished either by rotating the telescope orby the
useof a siderostat, whichisa plane mirrortilted soas to directthe starlight in a
direction which does not change during the day; the siderostat may feed a plain ...

The siderostats are driven in each axis by a novel drive system consisting of in-
line dual harmonic drive gear reduction units driven by stepper motors. The yoke
and mirror cell of each siderostat include provisions for accurately intersecting
the ...

The third line represents the external load at the tip of the siderostat that is
required to displace the tip by 1.0 micron; the corresponding maximum stress is a
small 0.2 psi. The structure is assumed to be cantilevered at the intersection of
the ...

Le Verrier—Magnificent and Detestable Astronomer
A siderostat conceived by Foucault, which he did not live to realize, was
constructed at the end of 1869 by Eichens and Martin, with special financing by
Napoleon III.36 At first it fed a fixed horizontal reflector with a 20 cm diameter 35

The ingenious scientist, Foucault, the perfecter of the siderostat, aimed to give the
equatorial the power of making the entire heavens pass before the observer
without his having to disturb himself or to displace the instrument. The siderostat,
as ...

The History of the Telescope
To avoid the expense of a large dome and equatorial mounting, and to ensure
adequate stability, the promoters, led by F. Deloncle, ordered from Gautier a fixed
-tube instrument fed by a siderostat.” The Teumont glassworks cast the 80-inch ...

A Polar Siderostat has a single mirror that reflects the light from a chosen part
ofthe sky into an objective or primary mirror. The French natural scientist Boffat
first introduced the concept late in the 17th century. Others employed the concept
for ...
