I’m trying to balance a tandem set up (side by side) with a 5” and 3” refractor. Can anyone share tips on balancing the DEC axis - I can’t seem to find anything out there so I’m guessing I’m searching for the wrong stuff! 3 D balancing seems to crop up a bit but I’m not sure what it is. Perhaps I should have the scopes piggy back given the difference in length?? Thanks in advance for any pointers. John |

Put your guide scope on the lighter of the 2 scopes and move your tandem bracket laterally until it balances.

Thanks Reg I can balance the scopes in any given position but the DEC goes out of balance as RA changes. So the whole thing balances perfectly home position but then goes increasingly out of balance in DEC while rotating in RA. I’m guessing it’s because of the different scope lengths one is 900 mm the other is 540. Just can’t get my head around how to fix it but I’m sure someone out there knows how. Just for guidance there is a 10 to 15 pound difference between the two scopes. John |
