ORION TELESCOPES & BINOCULARS 52588, Instruction Manual

Doing so will allow the pre-installed 3V CR-2032 button cell bat-
tery to make contact with the finder scope’s electronic circuitry 
to power the finder’s red LED illuminator. The tab can then be 
discarded.
To use the red dot finder scope properly, it must be aligned with 
the main telescope. This is easiest to do during daylight hours, 
before observing at night. Follow this procedure:
1.  First, remove the dust cap (M) from the front of the tele-

scope.

2.  With the star diagonal and 25mm eyepiece already in 

place from step 11 above, 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. Center the target in the eye-
piece by turning the slow-motion cables as needed to point 
the telescope. For larger telescope movement, release the 
R.A. and Dec. axis lock knobs (

Figure 7) and move the 

telescope tube by hand to the approximate location, then 
retighten the lock knobs and make finer pointing adjust-
ments with the slow motion cables.

 To install the equatorial mount, first remove the azimuth 

tension knob.

 Place the equatorial mount on the tripod, then secure 

it with the azimuth tension knob.
