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.
Getting Started
Stay-on-the-Scope Waterproof in Black
Water resistant multi-layer padded cases individually
designed to fit each model. Protects instrument while
fitted to a tripod and in use. Includes removable end
caps and adjustable carry strap.
Stay-on-the-Scope Waterproof in Green
As black models but supplied with a fully adjustable
neoprene carry strap for extra comfort.
Waterproof Cases
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.
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.
Care & Cleaning
Telephotography using SLR cameras (digital or film) and
compact system cameras. In this system the camera lens
is substituted for the fieldscope + telephotoadapter or
fieldscope + eyepiece + photoadapter. To convert your ES
fieldscope into a telephoto lens (ES 80 950mm1/f.11.9,
ES 100 1250mm1/f.12.5), you will need a 40215
telephotoadapter. Alternatively connect a suitable push
fit photoadapter to your viewing eyepiece.2A T-mount is
required to connect the assembly to the camera body.
Notes. Focusing is facilitated on the fieldscope. Camera may need to
be operated in manual mode with shutter locks disengaged where
necessary. The high magnification to aperture ratios result in slower
shutter speeds compared with conventional telephoto lenses so choose an IS0 setting of 400. For 35mm SLRs 400 ASA film is
recommended. If possible use a cable release or remote control to reduce camera shake when operating the shutter.
1This is an approximate figure based on 35mm SLR cameras. DSLR/compact system cameras use different sized image sensors
compared to 35mm so an equivalent telephoto conversion figure must be calculated separately.
2For information on push fit photoadapters visit our Digiscoping & Telephotography pages at www.opticron.co.uk
Digiscoping with digital compact cameras, camcorders and mobile phones
Shooting high magnification photos and video through your fieldscope is possible if you have
a suitable camera, camcorder or mobile phone. To find out how suitable or not your device
is for digiscoping, position it up to the viewing eyepiece and see if an image appears on the
screen. You may have to position the unit a few mm away from the eye lens of the eyepiece
and increase the zoom to get a full frame image.
To find out more about bespoke digiscoping kits, universal mounts and brackets visit the
Digiscoping & Telephotography pages at www.opticron.co.uk or contact Sales on +44 (0)1582 726522.
