Its been 31 years since I made my last telescope (I'm that old) and have decided to make a Newtonian again. I'm having a lot of fun selecting the components but am having trouble deciding where to put the focuser. Does anyone know of a 'rule of thumb' where the mirror focal plane should be relative to the outside of the tube? I mostly use Radian eyepieces and haven't selected the focuser yet.
