1. First, remove the dust cover from the front of the 

telescope. 

2. With the 20mm eyepiece installed in the focuser, point 

the telescope at a well-defined land target (e.g., the top 
of a telephone pole) that’s at least a quarter mile away. 

3. Center the target in the telescope eyepiece. 

4.  Next, you will also center the target object on the EZ 

Finder II’s red dot. Without moving the telescope, use 
the EZ Finder II’s altitude and azimuth adjustment 
knobs (shown in 

Figure 6

) to position the red dot on 

the object. 

5. When the red dot is centered on the distant object, 

check to make sure the object is still centered in the 
telescope’s eyepiece. If it isn’t, re-center it then adjust 
the EZ Finder II’s alignment again. When the object 
is centered in the telescope eyepiece and in the EZ 
Finder II, the EZ Finder II is properly aligned with the 
telescope. 

The EZ Finder II’s alignment should be checked before each 
observing session. At the end of your observing session, be 
sure to turn the power knob counterclockwise until it clicks off.
