Bugga, I thought I 'd got rid of them . Well it wouldn't be an image from Whyalla without dust LOL. Something has gone wrong with my flat fielding I've seemed to introduce something that causes dust donuts not to be completely removed. It might have had something to do with turning off dithering. Not saying that's the problem, but the dither may have been hiding a flaw in my technique. I thought I had got rid of them in photoshop, I will check my monitor anyway here is the last two again see if that is better.
