Getting Started
Your ES telescope will open up a whole range of new and exciting
impressions, whether for general use or specialist study. To get the
sharpest picture turn the focus wheel slowly until the image being
viewed becomes sharp. To minimise image shake caused by high
magnification the instrument should be supported using a suitable
tripod or mount. These mounts are connected to the telescope
tripod adapter socket located on the base of the tripod sleeve. If the
eyepiece being used has a fold down or retractable rubber eyecup
it should be used in the down position when wearing glasses. This
ensures the maximum available field of view is obtained. Be sure to
return the eyecup to the up position if you or anybody else wants to
view without glasses. The retractable lens hood should be extended
when viewing in bright sunlight. Make sure it is retracted before
fitting the integrated rubber objective lens cap.
Care & Cleaning
To clean outer glass surface of the eyepiece and objective lens, gently remove excess dirt and dust using a compressed
air device or blower brush. Caution. Hard and persistent rubbing of dirty surfaces can cause abrasive scratches on the
surface of the glass which may distort viewing. Breathe on exposed glass surface and then wipe with an optical
cleaning cloth (code 30277) in a circular motion until the surface is clean again. Do not attempt to dismantle the
instrument as this will invalidate the guarantee.
WARNING. Never under any circumstances use a telescope to view the sun. Doing so will cause serious damage to
your eyes.
Whenever possible store in a stable dry atmosphere away from moisture. For extra protection, use the gift box or one
of the optional cases available.
