2.
Mount the finderscope bracket (#4) by mounting the bracket over the studs protruding from the
tube and tightening it down with the supplied nuts.
3.
Slide the rubber O-ring over the eyepiece end of the finderscope and roll it 2/3 of the way up the
finderscope.
4.
Insert the eyepiece end of the finderscope through the bracket until the O-ring presses tightly
between the finder and the inside of the bracket.
5.
Tighten the three adjustment screws until they make contact with the finderscope body.
The finderscope is now installed and only needs to be aligned before it is used.
Attaching the Accessories
In order to use your telescope there are some standard accessories which must first be installed:
The installation of each is described
1 ¼" Diagonal (for #21077 & #21016): Loosen the thumb screw on the eyepiece holder located on the
focuser draw tube. Slide the smaller end of the diagonal (without the thumb screw) into the focuser tube.
Tighten the thumb screw to hold the diagonal in place.
Ocular: Loosen the thumb screw on the eyepiece holder (or 1 ¼" diagonal for #21077 & #21016). Slide
the barrel of the eyepiece into the eyepiece holder and tighten the thumb screw to hold the eyepiece in
place.
Aligning the Finderscope
Accurate alignment of the finderscope makes it easy to find objects with the telescope, especially
celestial objects. To make aligning the finderscope as easy as possible, this procedure should be
done in the daytime when it is easy to find and identify objects. To align the finder:
1.
Choose a target that is in excess of one mile away. This will eliminate any possible parallax effect
between the telescope and finderscope.
2.
Point the telescope at your target and center it in the main optics of the telescope. You may have
to move the telescope slightly to center your target.
3.
Adjust the screws on the finderscope bracket, tightening one while loosening another, until the
cross hairs are centered on the target seen through the telescope.
4.
Tighten the lock nuts to secure the position of the finderscope.
