I upgraded the focuser on my TOA-130 to a 4 inch focuser.
This may be useful for someone with a refractor who wants to upgrade their focuser.
Front end screw thread measures at 154mm in diameter. I have no other details of the thread. Happy to answer any other questions as best I can.
Draw tube travel is 80mm.
There are no accessories included. I have removed the plate with the serial number of my scope.
Beautiful focuser, but I needed the 4 inch diameter for a flattener, so this one has been sitting in a box unloved. Can't ever see me having a reason to use it again.
