I have the CCDT67 - and it works well with the RC10 and illuminates the APS size sensor on my Canon 20D.
BUT
It is a reducer only so you get field curvature in your image - quite normal for the RC design. With a full size sensor and an RC8 I expect you will see this issue. I think you will need a flattener more than a reducer - the HOTECH units get good reports.
Flatteners require exact CCD spacing to work well - reducers are not so sensitive (but you will not get the rated reduction if the sacing is not by the book).
The WO unit is a flattener/reducer and has adjutable spacing...but I do not think it works on the RC design - it is intended for refractors.
