PetersonEng - EZ Balance™ On-Axis Counterweight

Some SCTs are very nose heavy when equipped with a dew shield, and this is the situation that the EZ
Balance is designed to correct.  This simple but unique 3.3 pound counterweight has a thin flange that
fits between the telescope backplate and the EyeOpener (or the manufacturer's supplied visual back). 
It fits all 10" through 14" Meade and Celestron SCTs, from early models to current versions.  It does
not fit the LX400 series scopes.

The unique feature of this counterweight is that it is on-axis.  (Centered on a line that runs through
the center of the tube).  As long as you do not have any heavy accessories (such as a large secondary
telescope)  attached to the top of the optical tube the scope will stay in balance regardless of the 
orientation of the tube, and regardless of whether it is mounted on an Alt-Az or Polar type of mount. 


Do you need this counterweight"  Loosen your declination clutch.  If your scope is nose heavy you can
roughly simulate the effect of the EZ Balance by hanging a 3.3 pound weight from a string wrapped
around the scope's visual back.  You may still have a slight imbalance, but if this reduces the overall
amount of unbalance in your system you'll want the EZ Balance.  

The counterweight has a protective covering on the back of the casting to prevent scratching of your
telescope's backplate.  The counterweight is easy-on easy-off, so it can be readily removed to keep
weight to a minimum when carrying your 'scope.  No screws or rail systems are required.

Why balance your scope"  The drive motors and drive gears used in these telescopes are quite small. 
An unbalanced scope will lead to excessive wear on the drive train with early life failure of  motors
and gears.
