I have an early 2000's model of the WO Megrez 80. Great optics, however it still has the original focuser on it. Not knowing much about focusers, I still would like to upgrade to a 2 speed Crayford and hopefully be able to attach an EAF soon. (Original focuser is round and would not support the bracket I think.)
My question is, will any Crayford focuser for a 2in refractor fit this? I was told that the inside base flange diameter is 86.6. However, I can't find the specs anywhere on the internet to back this up.
I was hoping someone had some knowledge on these old scopes and could guide me in the right direction.
