If you find that it’s awkward to put your eye up to the eyepiece, you can rotate the telescope tube 
by loosening the knob on the tube clamp and moving the telescope tube until the focuser is in a 
convenient position.  Be sure to tighten it again! 

You may find that the telescope tube is either too hard to move or does not stay in place. Use the 
altitude adjustment tension knob (it holds the telescope to the upright part of the base) to find the 
right level of tension. 

Operating the EZ Finder 

A “finder scope” helps you point the scope, rather like a rifle sight.  The 

EZ Finder 

works by 

projecting a tiny red dot onto a screen mounted in the front of the unit, so that when you look 
through the screen, the red dot will appear to float in space.  Turn the power knob clockwise until 
you hear a “click” indicating that power is on.  With your eye positioned near the rear of the 
telescope, look through the EZ Finder with both eyes open to see the red dot. The intensity of the 
dot can be adjusted by turning the power knob. Use the dimmest possible setting that allows you to 
see the dot without difficulty. When the EZ Finder is properly aligned with the telescope, an object 
that is centered on the EZ Finder’s red dot should also appear in the center of the telescope’s 
eyepiece. Checking the alignment of the EZ Finder is easiest during daylight. Aim the telescope at 
a distant object, such as the top of a telephone pole or chimney and center it in the telescope’s 
eyepiece. Now, turn the EZ Finder on and look through it. The object should appear near or under
