Nipon Optics LV780-26-78x78 Installation instructions

NIPON 780X78 (LV780-26-78x78) Refra-Reflector Compact Telescope
User Instruction
1. Overview
This scope is featured with refra-reflect objective lens, which makes the instrument shorter, lighter,
non-chromatic aberration and more powerful. It combines spotting scope and telescope two in one.
The scope adopts the Maksutov-Cassegrain optical system. The objective lens has a focal length (F)
of 780mm, and its diameter (D) is 78mm. The scope has a standard 1.25” eyepiece holder that can
take a wide range of eyepieces with 1.25” (31.75mm) fitting diameter to achieve different
magnification levels and field of view. These features, plus its compact size and lightweight, make
this scope suitable for long distance observation, sightseeing, bird watching, and hunting during the
day, as well as observing stars and the moon at night.

5. Usage
 Stabilise the scope on a tripod (by connecting the tripod to the screw hole under the
tripod-fitting host of the scope, and tighten the connecting screw). Please do not try to make
an observation while holding the scope by hand, as it can be quite difficult to view an object
at such a high magnification power due to hand movement.
 If you use a large tripod, please adjust the height of tripod to a suitable level for observation.
Care should be taken to keep the tripod legs locked and steady.
 Turn the tripod host in azimuth and vertical direction as necessary. Care should be taken not
to turn the tripod direction adjustment screw with excessive force.
 Insert the eyepiece into the eyepiece holder of the scope.
 Aim at a distant object (at least a few hundred yards away – the further the better), and
adjust the focusing wheel clockwise or anticlockwise until the image is clear.
 Keep the eye as close to the eyepiece as possible (fold the rubber eyecup down if you wear
eyeglasses).
6. Maintenance
 Because this is a piece of precise and delicate optical instrument, please adjust the system
with smooth movement and equal power if possible. Prevent the system from shock and
vibration.
 Use a soft brush and lens cleaning cloth to clean the scope and the lenses when necessary.
 In order to keep the damp from fogging on to the lens, please keep the scope in a higher
temperature place for up to two hours after it is used in a cold and damp environment.
Warning: Do not use this instrument to directly observe the sun or other very bright,
light-emitting sources, or it can damage you eyes.
