Hi H,

Looking at it it seems like a custom fit is the only way. Without pulling it apart or closely inspecting it, it is hard to say which screws on the bottom you could potentially use: perhaps the 2 Phillips head screws up forward. The 2 aluminium thumbscrews aft might be useful, but unfortunately they are used for other focuser tension or locking.

It would be possible to make or buy a suitable split collar or lens tripod collar/clamp which you could mount up forward around the cylindrical body of the focuser. Also another possibility is that given the Bintel and GSO focusers appear identical perhaps there is an off the shelf GSO brand motor bracket/fixture available which might work (not sure you'd need to check).

Do you know the external diameter of the focuser? If so you could target a suitable collar. I suspect it's in the 60-70mm-ish range so something like one of these might be useful in providing a fixture point for the base for your bracket or a further custom simple bracket. The screw thread is typical 1/4-20 camera tripod screw thread. BUT don't take my word for it: verify any details, sizes, diameters in the any advert.....

There usually are also some sizes in the 70s, just keep looking if none suit
