As the images are taken at different points in time and from a different perspective I would guess that the shadow from a cloud that makes one part of the border of one image dark, but doesn't do the same to the same region in another image will cause photometrics to go wild occasionally if it tries to make the two brigjtnesses match. Also basically what you do is what the "stitching murals" tutorial does do => any checkpoint on nearby features will show a different parallax error than a point in the horizon.
As the question was if the images can be made sharper: does making more pictures and trying to make an HDR image help? This might average out some noise, but overlaying more images might produce ghost images of everything with an parallax error.
