CAMERAS REQUIRING EXTERNAL METERING DEVISES Set the light meter’s ISO index to the rating of the film being used. Select the magnification and not f/stop as explained above. If, as in many cases the smallest f/stop shown on your light meter is f/45 and you need a reading for f/56 or f/64, refer to the Light Extension Scale or increase the ISO setting as previously explained.

REMINDER

After using the Discoverer as a telephoto lens, the Telephoto Adjustment Control must be turned all the way counter- clockwise to resume use as a spotting scope.

QUESTIONS & ANSWERS

Q:Can I use lens filters on my Discoverer?

A:Yes, any standard 67mm diameter threaded filter will screw on to the objective lens exactly as does the lens cap. In long range telephotography, ground haze can diffuse the light between the camera and the subject resulting in a hazy appearing picture, lacking in contrast

Q:Will heat affect the image?

A:Yes, warm temperature conditions can cause the image to quiver or “dance”resulting in a blurred effect. This is not due to a defective scope, but rather the effects of heat mirage.

Q:Can I take pictures of the moon?

A:Yes, since the moon is illuminated by the sun, you can use the exposures shown in the instructions under “How To Determine Shutter Speed.” It is important to realize that exposure time increases as the moon wanes, with 10 times normal exposure necessary in its crescent stage.

Q:Is the Discoverer waterproof?

A:No, it is “shower tight”. If the scope has been exposed to moisture of any kind, wipe it dry as soon as possible.

CAUTION: Do no attempt to disassemble or repair any part of the Discoverer yourself. In doing so, you will invalidate your warranty. Special apparatus and considerable skill and experience is required to make even the simplest internal adjustment.
