Hi Robin

If you take a look at the image I think you'll see what I mean. The original
image is smeared slightly but the trailing removal technique smears the
image much more. Although the stars look better the nebulosity in the image
looks much worse, to me at any rate.  You need to study the removal
technique in PW to understand why it happens this way.
