For anyone is using this combination, how much counterweight do you use to balance the tube? It seems like the standard weight would be too little. Thanks!

I have the APM/TMB 130/1200, I added an 11 lb weight. The scope is 15 lbs. I am not sure what the SS is.

It is listed as 18.5 pounds, and the rings are another 3 pounds. Add in a finder, and I think that 22 pounds is a good number.

I'd just get 22 pounds in counterweight, but with the weights sitting at the end of a shaft and the scope closer in I know that it doesn't have to be 1:1. Thanks!

I was using mine on a CGEM with one 23lb CW about halfway down the shaft. The 21lbs losmandy weight should be enough as long as you don't any heavy accessories.
