The Finder Scope: 

 

The Finder scope (A) is a small telescope that sits 
on your telescope tube. It magnifies objects 5 times 
and has a light collecting lens that is 24mm. in      
diameter. 
 
When you look through the Finder Scope you will 
see an 

upside down image

. This is normal and you 

will quickly get used to it. 
 
The viewing field of the finder scope is much wider 
than that of your telescope and if you properly align 
the Finder Scope it will make it easier for you to  
precisely aim your telescope where you want. 
 

Installing Your Finder Scope: 

 
1)        Your Finder Scope (A) comes already         
           installed in its mounting bracket. This bracket 
           attaches to your telescope at the end where 
           the focuser (F) is located. If the Finder Scope 
           tube is wrapped in plastic, loosen the three 
           positioning screws (Fig. 3) on the bracket un
           til you can slide the Finder Scope out.          
           Remove the plastic and reinsert the Finder 
           Scope in the  same direction that it was posi
           tioned in before. Tighten the three positioning 
           screws. 
 
2)        You will see two chromed bolts sticking out 
           from the tube (Fig 3). Each one has two nuts. 
           Remove only the top nut from each bolt and 
           carefully set the two nuts aside. 
 
3)        Position the Finder Scope and bracket so that 
           the two holes in the bracket slip over the two 
           upright bolts and the larger lens of the Finder 
           Scope faces in the direction of the large lens 
           at the front of your telescope. Then thread 
           the two nuts you previously removed over the 
           two bolts. Tighten them firmly, but do not 
           overtighten, as you may crack the bracket.
