Thanks Big Fella!

I did go back and have a look at the PS file to check there was no clipping - just to be sure. The histograms are certainly very steep at the black end (typical of small galaxy shots), so I hyper stretched to check the shape. See the attached histogram (which shows a very exaggerated but otherwise invisible blue cast). You can see a nice tail at the black end in all 3 channels - so there is no clipping.

David is a brave man but he's right - treat yourself to a good monitor. Also do a check using my calibration image: http://www.pbase.com/gailmarc/image/75937224 . See also http://www.lagom.nl/lcd-test/ for a more detailed examination of your monitor.

You have excelled to pick that up so well.

Thanks Allan, much appreciated. Did you notice the very faint stubby tail at the bottom pointing downwards? There's also a faint element of halo above it as well extending towards the dwarf companion. You need a good monitor and a darkened room to see it.
