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.
