Hi all,

i am wondering if anyone can help out with this issue.
Appears to be in all my flats on a variety of filters (and might be in my lights too - just a bit) - centre zone of image, ending up with black speckling or noise? Fog / frosting / dirty flat panel?

crops of individual flat (with magnifier in DSS v5) / and individual light.

Thanks

Rusty
