Hi Marc. Work has kept me away for a while. In between busy periods at the moment so I've come up for fresh air. Indeed they are due to interstellar reddening caused by dust in the area. Don't think the Ha blend has done much for you on this image. Rather undersampled to boot - not sure if the combo is working for you. Will check out some of your other images.
