Opticron IS 70 R - Manual (Page 2)

Getting Started
Your IS 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
connected via the tripod socket located on 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.

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.
