I had similar problems on my old Tal-1m

I solved it by adding baffles to the main tube.. a little harder on a schmidt cassegrain.

The reflections are probably caused by the scope not the camera/corrector/filters, so I would try and track down other owners of your OTA and ask them... I'm guessing the solution will involve flocking,
