Oh yea!
A camera with no filter at all (as i think Houghy's is) is very red biased. Your 20Da has a different filter which lets through the Ha you want but still blocks the infrared, which causes the problems. Many people who use a modded camera start their processing (after calibration & stacking) by multiplying the red channel by 0.6 before doing anything else.
