Thats a stunning view of NGC55 Martin.
There is a pair of hard lines to the right and left the galaxy, where it would normally fade into the background (i dont know how to accurately explain what im seeing on my monitor) it looks a bit like the galaxy was cut out of another image and pasted in to this one.. do you know what I mean?
Its a fantastic image in any case, just that hard line bugs me a bit.
