You should make sure you protect the dark areas and only sharpen the bright parts of the image, Pete. The easiest way is to make a copy of the Luminance or Lightness and black clip it to make a mask.

MaskedStretch is a PI process that stretches an image iteratively but uses a mask to protect the bright areas of the image and prevent them saturating. It can be used as a substitute for HistogramTransformation (or can be used to do a mild stretch followed by HT to complete the stretch.)
