Opticron GS 52 - Manual (Page 2)

Getting Started
Your GS telescope will open up a whole range of new and exciting
impressions, whether for general use or specialist study. To focus at
different distances, simply turn the main focus wheel in
conjunction with the 9:1 ratio accurate focus adjuster 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.
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.
