That is excellent.

Love the dust lanes.

Lovely image Carole.

The colours look good and the large version has lots of detail.  As Mac says, the dark lanes have also come out very well.

You must be very pleased with that!

By the way, the large image shows that your new flatterner is doing an excellent job - there's almost no star distortion in the corners.

Thanks Mac, Mark and Phil.
Yes I am quite pleased with it, although I am kicking myself that there are a few blunders and it could have been even better.

1. Could not use the subs from Kelling or it would have been another 14 x 5mins on top (orientated too differently to be able to make a decent combination).
2. When I did the flats, the camera to Flattener was not quite tight and when I went to switch the camera on the camera rotated slightly, so a couple of dust bunnies resulted.
3. I was expecting to be able to use the 30 sec subs for the core that I took at Kelling, but because of the orientation I cannot seem to paste the subs from High Halden on top of the 30 sec subs done at Kelling, tried several methods but without success. So above image core is purely processed from the 5min sub.  Had I realised this would be a problem I could have done some 30 sec subs at HH.

You live and learn by your mistakes.

That looks lovely Carole.  To be picky the core does look a bit burnt out to me but you've brought out the dust lanes very well.  I've always found it difficult processing the bright areas like galaxy cores successfully, M31 is an extreeme case though.

I think that must be your best image yet, lovely.
