FOCUSING THE TELESCOPE & ALIGNING THE
CROSSHAIR FINDER SCOPE
1. Focusing (see Pg. 5, Fig. 3)
Leave the telescope in the same position as when assembling
(terrestrial position).
Loosen the set screw attached to eyepiece adaptor (#10) on
the main telescope tube.
Locate the lowest power eyepiece (20mm) and attach it to the
eyepiece adapter, tightening the set screws. Aim the telescope
at a distant object in the daytime, such as a stop sign, or corner
of a building etc. Rack the focusing knob (#8) back and forth
until the object is in sharp focus.
ALIGNING THE CROSSHAIR FINDER SCOPE
With the telescope in sharp focus, look into the finder scope
(#4). If the finder scope (#4) is not in focus, turn the finder
scope eyepiece (#6) around on its thread until the views are
sharp and clear. If the object you see in the main telescope is
not in the center of the finder scope cross hair, do the
following: tighten and loosen the three screws (#25) in the
bracket, causing the finder scope to move up or down, side to
side, or diagonally. When the object is dead center in the cross
hairs, your finder scope is adjusted. Repeat this process by
replacing the lower power eyepiece with a higher power
eyepiece. Once the image centered under highest
magnification in the telescope is also centered in the finder
scope, your finder scope is successfully aligned. It may now be
used for rapid location of sky-bound objects you want to
observe with the telescope. Occasionally, the focusing scope
may have to be readjusted.
Eyepiece & Magnification
This telescope is supplied with three different eyepieces (4mm,
12.5mm, and 20mm). The power of each particular eyepiece is
directly related to the focal length of the telescope which is
700mm (millimeters); However, the power of each eyepiece is
related to the focal length of the objective mirror of the
telescope.
The formula is as follows:
Focal length of the telescope
= Magnification
Focal length of eyepiece
For example , your 20mm eyepiece will show a magnification of:
700mm
= 35x Magnification
20mm
USING YOUR TELESCOPE ASTRONOMICALLY
Before learning the technical details of this telescope, you will
find that you can now enjoy observing the stars, planets and
moon.
THE MOON AND THE STARS
If you are viewing at night, you will get the most fun out of
looking at the moon and its cratered surface. Aim the finder
scope so that the moon is in the center of the crosshairs. The
main telescope is now directly aimed at the moon. The
moon
filter
will allow you to view the moon more comfortably by
lowering the brightness of the lunar surface. You can use the
moon filter included with your telescope by simply attaching it to
the male end of the eyepiece, then inserting the eyepiece into
the focusing tube like usual. Focus the telescope as described
previously.
At this point, try the more powerful eyepieces to observe more
detail of the moon. After looking at the moon, you will probably
want to look at some of the more well-known constellations (i.e.
the big dipper). The stars will appear as flickering dots of light.
This is the case with even the more powerful telescopes.
