Cheers Rod, yeah you need to have a decent screen, properly calibrated for brightness and contrast and then the dust is obvious
...many monitors are poorly calibrated for astro viewing and or we view in bright rooms. At home I have a well calibrated monitor in a study nook that I use for processing and a family computer, one of those all-in-one screen/tower combos and I can't adjust the screen fully, it stays quite contrasty, even at full brightness and the dust is visible ok but not as natural, the contrast takes the edge off subtle features and also makes noise a little more obvious in the faint areas. I usually also check my images out on various monitors at work too, to get the right balance. On the good ones it looks great
