Yep Lee. I do.
Here is an example of the same objects with and without the FR.
Same gear as yours: ED80 and camera equal to 6mm EP FOV. (DSI, LPI, Toucam, Neximage etc).
You will also notice that you will capture better colour at shorter exposures with a Focal Reducer
1. M83 normal ED80.
2. M83 with Focal Reducer in ED80
3. Trifid normal ED80
4. Trifid with Focal Reducer in ED80
