Geoff - here's where I have mine.

Your loss of image quality sounds like you have the system running too hot. I suffered this until I built a pulse-width controller for it. Being able to turn the heat down to where it was doing the job, but no more, was the key.

You do NOT want to heat the corrector plate. You want to WARM the air in front of the corrector and semi-trap it inside the dew shield area. You only need a differential of a couple degrees to prevent dewing.

Here's a photo of where I installed my home-made strip, and it works fabulously well and does not affect image quality because the heat is set to the bare minimum for the effect to work. I turn it on at the beginning of the evening and let it reach temperature well BEFORE it is needed.
