Hi Guys,
I have recently bought a 2" dual speed focuser 10:1 to replace the old crayford focuser for my F/9 Refractor. There are 3 screws that locking the old focuser in place, the first 2 screws have been removed successfully without much problem. However, the last screw is playing up with me and the screw head is now stripped.
Is that any solution that I can remove the stripped screw without damaging the telescope?
Any help would be much appreciated.
