Part I – Construction
1. General/Location
Before you begin assembly, choose a suitable location for your telescope. It
is best to build the telescope in a place where you have a clear view of the
skies, a stable footing and sufficient space around you.
Before beginning assembly, remove all the parts from the packaging, and,
using the diagram, check to make sure no parts are missing.
2. Tripod
Take the tripod (9) out of the box. Carefully open the legs and place the
tripod on a level surface place and lock the accessory tray (13) on the centre
knob and rotate until it snaps in place (No. 3).
Note: Please do not forget to remove the accessory tray before collapsing
the tripod.
3. Telescope
Loosen the screw in the dovetail mount so that it is completely retracted
(No. 4). Place the telescope with the dovetail in the mount and tighten the
screw. Make sure that the National Geographic logo is upright.
4. Altitude knob
Loosen the vertical knob by rotating it anticlockwise, align the optical tel-
escope tube (1) horizontally and retighten the knob (No. 5).
5. Mount
Place the mount base's mounting holes on the tripod's mounting screws and
tighten them (No. 6).
6. Eyepiece
Remove one eyepiece from its eyepiece holder (6) and slide it into the
eyepiece connection (3). Tighten the holding screws (No. 5). Start with the
lowest magnification eyepiece, which has the highest focal length printed on
it (e.g. 20 mm or 25 mm, depending on your model) to locate objects and
find the correct focus. If you have the object you want to view centred in
the field of view, switch to a higher magnification by using an eyepiece with
