HAND HELD TELESCOPES
GEORGIAN (18th - 19th century)
A
very rare EIGHT DRAW antique telescope, signed on the
first draw “ADAMS’S New Patent portable
Telescope, No. 60 Fleet Str., London” and
dates to the end of the 18th century.
The telescope
has
it’s original leather cover to the barrel, a removable lens
cap to the objective and dust slide to the eyepiece.
This instrument extends from 5 1/2 inches closed,
to
nearly 29 inches long when fully opened and has a 1 1/2 inch diameter objective.
The optics, as best as I can tell, are all original and in very good condition
with a “green tint” achromatic doublet objective and
magnifying first draw. The draws are all in good condition with no significant
damage and focus smoothly. The leather is intact with slight signs of shrinkage
commensurate with its age of around 220 years. A very rare telescope by the
world’s best instrument makers of the day.- £850
A
long antique decagonal tapered barrel telescope
from the late 1700’s, signed on the draw tube by Watkins,
London (1747 – 1784). This
very rare single draw “transitional” telescope has a decagonal
tapered mahogany barrel, the barrel
itself is 36 inches long and tapers from about 2 inches
diameter at the objective to 1 3/4 inches diameter at the eyepiece end. Overall
the telescope is 37 ½ inches long when the eyetube is pushed fully home and
draws out to 44 inches long to focus on objects a few yards away. The 1 ½ inch
diameter objective lens looks to me to be the original achromatic doublet in a
sealed cell developed by Dollond and Watkins in the mid 18th century
and the telescope has dust slides to both the objective
and the eyepiece. The non-retained 5 lens eye tube
unscrews into sections,
for cleaning. The telescope is complete and in fine condition for a 250 year old
instrument, focuses clearly, has all original optics (as far as I can tell) and
is complete. The only damage I can find is to one of the eye tube lens retaining
rings which appears to have been caused whilst some
previous owner was trying to remove one of the lenses for cleaning. This is a
very fine example of the 18th century decagonal, transitional
telescope which gives a good depth of field and wide field of view compared with
its contemporaries. - £995
A large antique
hand held telescope engraved on the draw tube, by Dollond,
London. A 2 inch diameter green achromatic objective lens is set
into the taper barrelled mahogany body tube, and has a sliding ray shade and
removable dust cap. The draw tube is engraved
in script, adjacent to the eyepiece, with the makers name. There is a single
draw tube, comprising 3 sections to make up the
erecting set and the eyepiece set of optics and dust slide
to the eyepiece. The telescope extends to 48 in. long
in total, from just under 38 inches fully closed. It
has some minor scratches on the polished mahogany barrel and plenty of original
lacquer on the brass work, consistent with it’s 200 or so years of age and is
in fine working order. The lenses are free from any significant flaws and the
telescope focuses clearly and smoothly. - £475

A
pair of Antique Brass Galilean field
glasses
or Binoculars, impressed around each eyepiece “THE
LIVERPOOL”. These type of field
glasses were made from the middle of the 1800’s until optical prism technology
overtook the simple Galilean optics in the early 20th century. These, all brass,
binoculars are in good condition with brown leather covered barrels, and sliding
ray shades. The optics are fine and free of any significant scratches, chips or
cracks and they focus smoothly giving a clear image. They measure just
under 6 inches in length with shades extended and compress down to 4 inches for
storage. The main lenses are 2 inches diameter, and
the general finish is very good for the age. A fine example of this mid 19th
century instrument.
