Eyepieces
Your ES fieldscope will bring a new dimension to long range observation bringing far away subjects into clear and
sharp focus.
1. To minimise image shake caused by the high magnification, the instrument should be supported using a suitable
tripod or mount.
2. Connect the fieldscope to the tripod or mount using the tripod socket located on the underside of the tripod sleeve.
3. Make sure the eyepiece is attached securely. The retractable rubber eyecup 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.
4. To focus, locate the subject in the centre of the field of view and rotate the focus wheel until the subject comes into
sharp focus. At high magnifications when depth of focus is shorter use the fine focus adjustment for greater accuracy.
5. If you are using a variable magnification or zoom eyepiece set the magnification to minimum when trying
to locate your subject, only zooming once the subject is centred. With some eyepieces a small amount of
refocusing may be required as the zoom is adjusted.
6. The retractable lens hood should be extended when viewing in bright sunlight.
WARNING. Never under any circumstances use a fieldscope to view the sun. Doing so will cause serious damage
to your eyes.
