JC-1000 Instruction Manual
FINDERSCOPE ADJUSTMENT
As the telescope only offers a limited field of view, it may be fairly
hard to locate a given star or planet for observation. This is why the
telescope is fitted with a cross-hair finderscope for orientation
purposes. We recommend performing the following adjustments
in daylight.
1)
2)
Insert the eyepiece with the lowest magnification factor into
the angle prism connector. Observe an easily recognizable fixed
object that is no more than 300 meters away. Swivel the telescope
through its horizontal axis and adjust it along the vertical axis until
the object is located right in the center of your field of view, then
immobilize the telescope by tightening it down securely.
Now look through the finderscope. If the object seen through the
telescope cannot be seen, slacken the adjusting nut and move
the finderscope until you can see the object. Then tighten down
the adjusting nut making sure that the object remains visible in
the center of the finderscope. To simplify this procedure, use the
adjusting nut to position the object in the center. The finderscope
will move in the direction in which the nut is turned. As soon as the
eyepiece adjustment coincides with that of the finderscope, all of
the nuts can be finally tightened down.
