Not ideal conditions with the Moon 1-day before full and from home in the suburbs. I wanted to test a guided image using my Canon 70D and 18-200mm EF-S lens rather than fixed tripod. There is obvious vignetting to the corners and a spot on the lens (mid right) so flats are required. Also a suburban light gradient to the bottom right (west). See also cropped image salvaged from this.

Cropping has reduced the vignette but I'd wanted to retain the Jewel box clutser (mid left edge) so the crop is not tight enough to remove the most obvious parts it.
