Well done Steve, the glow effect is still a nice, soft touch to the shot.
Apparently, from really dark observing sites in the last few days some people have spotted the comet with the naked eye. It's getting closer to the Sun now, isn't it?

Many thanks all. Keith I used the 'Comet and stars stacking : "star freeze effect"' in DSS to stack. DSS does the usual star stacking method and then I had to go through each frame to indicate the position of the comet.
DSS then creates a first stack to extract the comet from the background.
Then a second stack is created to freeze the stars (the comet is subtracted from each calibrated and registered light frame before stacking it). Last, the final image is obtained by inserting the comet back in the image, in DSS.
There was still some faint star trailing evident in the final DSS image, so I created and artificial flat to minimise this effect.
Seanie... hopefully I will get an opportunity to capture it again as it gets closer to the Sun.
Cheers
