Thanks everyone! I'm very proud of this little image as I really didn't have that many pixels to work with. A lot of work went into it so it was a very, very pleasing result.
One thing I failed to point out was that, like my first effort, this image uses a 2x Barlow in the image train giving an effective focal ratio of f/14 to f/15. Another thing - I know this might sound odd - I've just noticed that I've managed to image Titan as well. Either that or I've got a smudge that appears in the same spot that Titan was in at that time!!
Very exciting to see Titan...
Cheers,
Mario
