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  

lNDERSCOPEANDROLLITOFTHEWAYUPTHElNDERSCOPE

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.

Optical Tube Assemblies

Depending on the telescope kit you purchased, you may have received one of the following optical tubes.  This section of the 
manual will walk you through the setup of the basic types.
