Thanks all. Processing is half the battle after getting the data to start with. Initial processing in IRIS then finishing off in photoshop seems to work best for me. Having polar alignment so accurate that DEC adjustments are hardly needed even on 10 or 15 minute sub's makes hand guiding that much easier too.

My Mount sits on reactive clay so alignment changes over just a few nights.
