Hi Markus,
I believe your scope has a 2 inch focuser, so if you used a 2 inch Plain Male to M42 T2 camera adapter, which sometimes have an INTERNAL M48 x0.75 thread then you could mount your 2 inch filters to the M48 internal thread and possibly the camera/eyepieces somehow at the other M42 end with the right adapters etc, (excepting 2inch eyepieces of course)..
Something like this....

and possibly one of these mounted to the rear of the above adapter in order to mount 1.25 inch eyepieces...
