![]() ![]() ![]() It's a recurring problem I find, hence my choice not to use a service center, as I'd be back there in another 6 months! But for now it's a huge improvement - thankfully. While not perfect it removed about 80% of the 'muck' for me - another couple of such procedures and I'll probably have it clean. I Used strips of Zeiss lens-cleaning wipes the width of the sensor, held in cover-slip forceps (as they have squared ends to their jaws rather than points) and dragged (dampened with lens-cleaning spray) across the sensor - one drag per piece then a new piece - about 20 times. Yes I've recently bought such a blower or 'rocket' as they're known! They're very good indeed, but my sensor was past the 'blow it off' stage. You can buy them for much cheaper and it cleans the sensor chemical free and without haven't to physically touch it. I find a good item to use when cleaning a camera sensor is an air blower like this one here. John - You are right, Liveview does make the sensor a lot more exposed.

In Zerene, When the stack is completed, go to "Start Retouching". In this particular image it is very easy to retouch that. But when run a stack and you allow x/y shifting, or magnification changes, you will get the dust "trails" (Much less so with Helicon Focus Method "B"). Not too bad if you are re-touching a single image. In these cases be sure the brightness adjustment is checked. When you have a soft, out of focus background it can get pretty shabby looking when there are some significant exposure variation in the frames. Don't know why, the exposure times are the same). I noticed in the source files there is a significant difference in brightness with some (the last few especially are much brighter. You should get a hugely improved rendition than the one you posted. When, halfway through the stack, the program shows a slider to set the threshold use about 84% for this stack. Don't use any "auto" value for the threshold setting in preferences. I downloaded your source files and had a look. ![]()
