Opticron HR ED - Manual (Page 3)

Getting Started
Your HR ED 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.
