I'm hoping someone with a 10" or 12" GSO or Bintel Newtonian may be able to provide some data for me. I need the centre-centre distance for the mounting holes of the Crayford focuser on these scopes.
Hi Mark,
I have a LB12". It takes both the std Crayford + the 10:1 that I have just fitted.
They both fit on the same base, the distance centre to centre is 70mm.
