Hey Lewis,
In trying to sort out my own focuser upgrade options i found this base plate from the feather touch selection.

might make it easier for you!
i'm still battling to find out if i am able to install a 2" moonlite / feather touch focuser in place of the 3" on the bintel gso scope. a bit hard when i haven't got it yet. details seem scant!
cheers
