ADJUSTING THE FINDERSCOPE
Since the telescope has a limited field of view, it can be quite difficult to locate a given star or planet. For this reason the
telescope is fitted with a finder scope with reticule for orientation. It is advisable to complete the following settings in daylight:
1)
Insert the eyepiece with the lowest magnification in the Zenith mirror or Zenith prism. Look at a stationary. Easily recog
nizable object that is not further away than 300m. Turn the telescope with the horizontal axle, and move the vertical axle
until the object is in the middle of the field of view, and then focus the image. Tighten the adjusting screw on the mount
so that the telescope remains in this position (the higher the object is above the horizon, the easier it is to locate).
2) Now look through the finder scope. If the object seen through the telescope is not visible, than release the adjusting
screws and move the finder scope until the object can be seen. Now retighten the adjusting screw while ensuring that
the object remains visible in the finder scope. To simplify this procedure use the adjusting screws to adjust the object in
the centre. The finder scope will move in the direction of the screw in which it is being turned. All screws can be finally
tightened as soon as the setting with the eyepiece coincides with that of the finder scope.
ALTITUDE AZIMUTH MOUNT
The telescope is fitted with an Altitude Azimuth mount. “Altitude” refers to the up and down or vertical movement of the
telescope. While “Azimuth” refers to the sideways or horizontal movement. The Altitude Azimuth mount, in conjunction with
the micro adjustable Altitude control (A), and Azimuth lock (N) enables you to observe the entire night sky, or any celestial body,
without having to move the tripod.
WHICH MAGNIFICATION?
SELECTING THE CORRECT EYEPIECE
Magnification defines the power of a telescope to enlarge an image or to 'pull it in' closer for viewing.
Example:
700mm focal length ÷ 12.5mm focal length of eyepiece = 56x magnification
The required magnification depends upon the object being observed. The following general guideline is recommended for this
purpose: ideal viewing conditions are obtained if the magnification is more than 15x - 20x the diameter of the objective lens, i.e.
an optimal magnification of 100x - 125x can be expected with a 60mm dia. Objective lens to observe most celestial objects. A
lower magnification power is advisable for the observation of stars. The field of view is wider so that the object for observation
is more easily localized. The highest magnification power should only be used for particularly clear observations of the moon an
object that is relatively close and exceptionally bright - so that good detail resolution is achieved at high magnification ratios.
BARLOWLENS
The Barlow lens increases the magnification of the telescope. A 3x Barlow lens will therefore treble the telescope's
magnification power. Consequently A 56x magnification can be trebled to 168x with a 3x Barlow lens. The highest magnification
power of the Barlow lens should only be used for large and bright objects such as the moon and the brightest planets, as well
as for nights with optimal observation conditions.
Do not use the Barlow lens and the erecting eyepiece in conjunction with the angle prism as this produces a particularly low
resolution level with the result that the image can no longer be sharply focuses. To use the Barlow lens take the angle prism out
of the tube. Insert the Barlow lens into the focus tube and then attach the required eyepiece to the Barlow lens. Focusing is then
completed in the customary manner.
GENERAL REMARKS
Avoid sudden temperature fluctuations as the moisture in the air will condense on the objective lens. Should this happen, than
place the objective lens not too close to a source of heat and allow the moisture to evaporate slowly.
CAUTION
To avoid eye damage never look through the telescope into another optical instrument, and never view into the sun.
