Slowly unlock the R.A. and Dec. lock knobs. 
Rotate the telescope until both the optical tube 
and the counterweight rod are horizontal to the 
ground, and the telescope tube is to the side of 
the mount (Fig.a).
Tighten the Dec. lock knob.
Move the counterweights along the counterweight 
rod until the telescope is balanced and remains 
stationary when released. 
Tighten the counterweight thumb screws to hold 
the counterweights in their new position.

A Telescope should be balanced before each observing session. Balancing reduces stress on the 
telescope mount and allows for precise control of micro-adjustment. A balanced telescope is 
specially critical when doing 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 level and on a stable surface. For photography, point the telescope in the 
direction you will be taking photos before performing the balancing steps.

Dec. Balancing

The R.A. balancing should be done before proceeding with Dec. balancing.

Release the R.A. lock knob and rotate around the R.A. axis so that the counterweight rod is in a 
horizontal position. Tighten the R.A. lock knob. 
Unlock the Dec. lock knob and rotate the telescope tube until it is parallel to the ground.
Slowly release the telescope and determine in which direction it rotates. Loosen the telescope 
tube rings and slide the telescope tube forward or backward in the rings until it is balanced.
Once the telescope no longer rotates from its parallel starting position, re-tighten the tube rings 
and the Dec. lock knob. Reset the altitude axis to your local latitude.
