How does the Edge 8 + 0.7x reducer compare with the C8 + f/6.3 corrector?

If you mean the standard rear cell 6.3 reducer/corrector... the edge HD is far beyond that. If you mean a corrector from starizona or something... then it becomes more of a fair fight. The edge optics are amazing and it doesn't go unnoticed.

Visually, there's not much difference. The stars at the edge of the field with the Edge and f/7 reducer are noticeably better, but it is not like night and day. OTOH, the field is a little wider with the Jim Riffle designed Celestron reducer/corrector (which IMHO is better visually than its competition), but it is not like night and day.
For the average person, a standard SCT and the 6.3 r/c still makes a lot of sense.

In my experience for both imaging and visual the EdgeHD is a much better system. The cooling vents and mirror locks are also really useful.

Although I didn't care for either (visually), I found the EdgeHD/0.7X combo better ad of course more $$$$.
