I'm using a null adapter on mine but still get reflections from the glass on the sensor (that'll teach me to keep it so clean ) back to the back of the MPCC glass on bright stars. So there's no filter at all between the sensor and the MPCC. Are you saying that if I stick an astronomik filter between the two I'll kill any potential reflections?
