Im thinking if I do it 250mm and have a small reduction at the top ( say over the last 30mm or so) down to 180mm for the Titan adapter then this might just do it.
Jeff, are you sure about the pier being 1800 out of the ground? With a decent mount on top of it, your scope will be 2 metres or more off the ground.
