ligning

the Finderscope

1) Focus the telescope eyepiece on a distant object.
2) Once the object has been centered in the telescope 
    view, ensure the locking screws are tightened.
3) Use the three alignment screws to center the 
    finderscope crosshairs on the object seen in the
    telescope view (Fig.a). 
    
    

Depending on telescope design, the object may appear 

    inverted in the telescope view. 
    Do not over-tighten the three alignment screws 
    on the finderscope mount.

OPERATING YOUR TELESCOPE

Fig.a

Telescope should be balanced before each observing session. Balancing reduces stress on telescope mount 
and allows precise control of micro-adjustement. A balanced telescope is specially critical when using the 
optional clock drive for astrophotography.  

The telescope should be balanced after all accessories (eyepiece, camera, etc.) have been attached. Before 
balancing your telescope, make sure that your tripod is balanced and on a stable surface. For photography, 
point the telescope in the direction you will be taking photos before preforming the balancing steps.

R.A. Balancing

 

1) Adjust altitude of the mount to between 15º and 30º by 
    using the altitude adjustment T-bolt. 
2) Slowly unlock the R.A. and Dec. lock knobs. 
    Rotate the telescope unitl both the optical tube 
    and counterweight rod is horizontal to the ground, 
    and the telescope tube is to the side of the mount. (Fig. b)
3) Tighten the Dec. lock knob.
4) Move counterweight along counterweight rod until 
    telescope is balanced and remains stationary when released 
5) Tighten counterweight thumb screws to hold the counterweight 
     in its new position. 

Dec. Balancing

All accessories should be attached to the telescope before 
commencing with balancing the declination axis. The R.A. 
axis should be balanced before proceeding with Dec. balancing.
1) Adjust altitude of the mount to between 60º and 75º. 
2) Release the R.A. lock knob and rotate R.A. axis so that the 
    counterweight rod is in horizontal position. Tighten the R.A. thumbscrew. 
3) Unlock the Dec. thumbscrew and rotate telescope tube until it is paralled to the ground.
4) Slowly release telescope and determine which direction the telescope rotates. Loosen 
    telescope tube rings and slide telescope tube forward or backward in the clamps 
    to balance Dec. axis.
5) Once telescope no longer rotates from its parallel starting position, re-tighten tube rings 
    and the Dec. lock knob. Reset altitude axis to your local latitude.
