FINDERSCOPE ASSEMBLY
INSERTING EYEPIECE (Fig.10)
1) Unscrew the thumbscrews on the end of the focus
tube to remove the plastic endcap.
2) Insert diagonal and re-tighten thumbscrews
to hold diagonal in place.
3) Loosen the thumbscrews on the diagonal.
4) Insert the desired eyepiece into diagonal
and secure by re-tightening
thumbscrews.

Locate the finderscope bracket and carefully remove
the rubber-o-ring from it. Position the o-ring into groove
on the finderscope tube (Fig.7).
Slide the finderscope bracket into the mounting slot and
tighten the screw to hold the bracket in place (Fig.8).
Loosen the two adjusting screws on the bracket.
Position the finderscope into its backet by sliding it
backwards until the rubber o-ring seats. Align as
described below (Fig.9)
These fixed magnification scopes mounted on the optical tube are very
useful accessories. When they are correctly aligned with the telescope,
objects can be quickly located and brought to the centre of the field.
Alignment is best done outdoors in day light when it's easier to locate objects.
If it is necessary to refocus your finderscope, sight on an object that is at
least 500 yards (metres) away. Loosen the locking ring by unscrewing it back
towards the bracket. The front lens holder can now be turned in and out to
focus. When focus is reached, lock it in position with the locking ring (Fig.11).
1) Choose a distant object that is at least 500 yards away and point the
main telescope at it. Adjust the telescope so that the object is in the
centre of the view in your eyepiece.
2) Check the finderscope to see if the object centred in the main telescope
view is centred on the crosshairs.
3) Use the two small alignment screws to centre the finderscope crosshairs
on the object. The screws work in opposition to a spring-loaded knob (Fi.12).
