GM-8 and TMB 130 SS new

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!

Mike

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.
