inches (26.7 cm) wide, and is 4 7/8 inches (12.4 cm) deep. The
sextant features a worm gear drive that can be overridden for
large angular movements. A micrometer drum mechanism is
used to precisely change and read the azimuth
angle. Squeezing the mechanism disengages the gearing for
smooth, large angle moves The 8-inch sextant have six filters
mounted on heavy swing-arm mounts. The telescope
produces a bright clear image, and can be extended to focus
and collapsed for storage. The index mirror has three inset
adjustments to align the optical path. The mirrors are aligned
at the factory and checked prior to shipping When the sextant
is set to zero degrees, the image through both optical paths
as viewed through the telescope align to produce a single
image. Moving the index arm causes the image to split in
half. When viewing two objects, such as the horizon and a
celestial body, the index arm is adjusted until the two are
superimposed. The micrometer drum reads out the angle
between the two objects. The micrometer rack is cut directly
onto the limb of the sextant. The sextant’s handle is made of
hardwood with a brass plaque. The sextant is fully functional,
but has not been calibrated and is not intended for navigation
