Quote:My mach 1 GTO currently holds a 1988 6" f/8 refractor. It takes three of the 9 pound counterweights to balance this. (two of the weights are at the end of the travel and one could be slid out about two more inches) I'd like to add my 80mm William Optics as a guide/finder. With rings etc. it is close to another 10 pounds. Another 9 pound AP weight may not be enough. But a Losmandy 11 pounder might be enough and a Losmandy 21 pound would be excessive, allowing me to remove a couple of the 9#'s. The AP shaft diameter is 1.125" while the Losmandy shafts are 1.250" so the Losmandy weight could fit. With the locking bolt the Losmandy C. W. won't flop around. Or will it?Musings over Monday morning coffee.Especially the 'sacrilege' bit......Dave

I lost count of my scopes. Now I just want mobility. I came, I saw, I bought some interesting accessories, and put names to faces: NEAF 2012, ASAE 2012, SWAP 2013, ASAE 2013.
