Robbie, I had a 10" LX200GPS, and now a 12" LX200R, and with an MX7C camera, I could use the f/3.3 focal reducer.
However, when I changed to the larger 'chip' SXVF-H9C, I could no longer use the F/3.3 reducer, as it produced the effect you describe. Its just not suitable for anything other than the smaller CCD's.
The f/6.3 is fine, but of course won't give as large a field of view, as did the f/3.3.
Forgive me if I'm "teaching granny to suck eggs" here, but with any focal reducer, its essential to get the spacing between the focal reducer and the CCD correct, in order to achieve the stated focal ratio.
There is a formula for calculating this. With your f/10 scope, and the f/3.3 focal reducer, a spacing of 57mm, will give f/3.29. This is of course the theoretical distance, and manufacturing tolerances, would likely require some small adjustment of the spacing.
I arrive in Perth this weekend, for a five week stay with my daughter, and if I can be of any help, just give me a 'shout' via the forum.
Regards
Dave
