RE: (ATMoB:Discuss) Counterweights for Dobsonian

I have a 10" Coulter and needed to balance both a telrad and finder.  I used 2 x 5 lb dumbbell weights. I attached one to the end of the tube and the other to the side of the tube opposite to the finder and telrad.  I tried to get them as close to 180 degrees away from the attached equipment so that the tube would be balanced in all orientations.  If not, you may have problems particularly at zenith.

I'm looking for suggestions on how to counterweight my 10" Dobsonian.  I added a TelRad and now its top-heavy.  Thanks for any sources or suggestions.
