This is a massive and beautiful 40" (102 cm) Ross London brass double barrel
telescope and fine wooden tripod reproduction crafted in the old style. This 52
mm. telescope has ground glass optics and produces a sharp image; it focused by
rotating a large adjusting ring near the eyepiece. A brass lens cover on a
chain, a sighting telescope that can be adjusted from
9.5 to 13 inches (24 cm to 33 cm) in length, a main eyepiece on the primary telescope
that extends over 2 inches for exact focusing. The tripod legs extend from a length of
37 inches (94 cm) to 63 inches (160 cm), so that the telescope can be positioned for
comfortable observation. The telescope can be easily removed from the collapsible
stand. The telescope itself has a full 360-degree horizontal range of motion around the
tripod, and 180 degrees vertical. A treasure that is sure to impress the most
distinguishing telescope collector.
Magnification is 24X and is designed keeping in view the requirements of a nautical
scope - I.e., greater field of view. More the magnification, less expansive is the field of
view and for a nautical scope this 24x specification coupled with the huge 52 mm lens
gives the best combination of steadiness and field of view with satisfactory
magnification. Please note that this is designed as a terrestrial scope and not advised
for astronomical observations, although it does make the moon look rather nice!
This is a very rare example of a truly practical Harbourmaster - so called because it is
often used to detect incoming sea traffic. You can spot the target with the spotter
scope and then focus for a grander view with the main telescope. This unit is designed
as a terrestrial telescope and is recommended to those who have a good view of the
sea or of a city's concrete jungle. The telescope and tripod weigh 13 kg. |
