Ill shead some light on the subject seems though i have a SW 10" (well
whats left of the SW parts)
Unlike the GSO's SW can be used directy to focus with a DSLR. But because of this you need to bring the Eye pieces out alot further, to the point that you need a extension tube straight up (approx 50mm) hence the 2" adaptor, better connection and no floppy eyepieces.
The problem that you come up with is if you want to put any filters/correctors for photography the "non standard collar (the ring at the top of the drawtube where the thumb screws are) is about .8mm to small and hence stopping your 2" eps/filters/mpccs from going all the way down. BAD JOO JOOS!
Recently i did a small modification to Yugents 10" to accept the MPCC and also retain the useage of the M42 T thread (the 1 1/4 ep adaptor unscrew the nose piece youll see what im talking about). Works a treat.
Go forth and pluner!
