Setting Up the Refractor (#21020)

Installing the Finderscope

To install the finderscope onto the telescope, you must first
mount the finderscope through the finder bracket and then
attach it to the telescope Toward the rear of the telescope
tube, near the focusing assembly, there is a small bracket
with a set screw in it This is where the finderscope bracket
will be mounted To install the finderscope:
1 Slide the rubber O-ring over the eyepiece end of the
finderscope and roll it 2/3 of the way up the finderscope
2 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

3 Tighten the adjustment screws until they make contact
with the finderscope body
4 Locate the mounting bracket near the rear (open) end
of the telescope
5 Loosen the set screw on the mounting bracket on the
telescope
6 Slide the finder bracket (attached to the finderscope)
into the mounting bracket on the telescope
7 The finderscope bracket will slide in from the back
The finderscope should be oriented so that the objective
lens is toward the front (open) end of the telescope
8 Tighten the set screw on the mounting bracket to hold
the finderscope in place

Installing the Eyepieces

The eyepiece, or ocular as it is also called, is an optical
element that magnifies the image focused by the telescope
Without the eyepiece, it would be impossible to use the
telescope visually The eyepiece fits directly into the focuser
To attach an ocular:
1 Loosen the set screw on the eyepiece adapter so that it
does not obstruct the inner diameter of the barrel
2 Slide the chrome portion of the eyepiece into the focuser

To remove the eyepiece, loosen the set screw on the
focuser and slide the eyepiece out You can replace it with
another ocular
Eyepieces are commonly referred to by focal length and
barrel diameter The focal length of each eyepiece is printed
on the eyepiece barrel The longer the focal length (i e , the
larger the number), the lower the eyepiece magnification
(i e , power) The shorter the focal length (i e , the smaller the
number), the higher the eyepiece magnification Generally,
you will use low-to-moderate power when viewing
Your refracting telescope can use eyepieces with both a
1 25" and 2" barrel diameters To use a 2" barrel eyepiece,
the 1 25" eyepiece adapter must first be removed To do this,
simply loosen the two chrome thumbscrews located around
the focuser barrel and remove the 1 25" adapter Once
removed, a 2" eyepiece or accessory can be inserted
directly into the focuser barrel and secured with the two
thumb screws
Your telescope comes with a 1 25" star diagonal This
diagonal can be inserted into the end of the 1 25" adapter
allowing you to use 1 25" eyepieces at a more comfortable
angle when viewing near the zenith
