Skywatcher MN190 focuser advice

[Thommy]

Dear all,

I recently bought a new MN190 that is going to be used for deep sky photography. I am quite satisfied with the focuser except for the internal extension tube. Even when it's not extracted, the camera and FW wobbles quite a bit. Any of you had a fix to this problem? My idea is to bolt it to the focuser and use external extension rings if needed. But this is easier if the internal extension tube is removed from the focuser first - do any of you know how it is fixed to the focuser?

By the way, I don't want to replace the focuser with a moonlite or similar - just fix the original.

Thanks,

Really no advice on how to fix the internal extender of the original MN190 focuser?
