Because of the lack of the Celestron 0.7x Reducer for the EdgeHD800 here at German sellers, I have tested the TS CCD47 0.67 Reducer from my old RC Telescope.
The result is in my opinion surprisingly good, I see only in the outer corner some elongated stars. For me the sharpnes is ok, I don't think, that you can in this night with very poor seeing expect a lot more.

So, this is a quiet cheap alternative; the back focus with it is easily to adjust and for me with my Baader click-lock it was also easy to adapt. The ideal back focus from the Reducer is 85mm, maybe interesting for someone with a filter wheel and other gear.
