I then went through the process in StarTools and got (what I thought) was actually a very good image, with good detail in Cigar and quite a distinct swirl in Bodes. The problem was a fuzzy border. On a full screen it was about 1cm thick and stated about 0.5cm from the edge, a bit like a thick rectangular picture frame but not right up to the edge of the image. In the end all I could think of was to crop it out which was ok but I just wonder where it came from and how I could have got rid of it. Any help will be gratefully received. Kind regards, P.
