Very nice result Paul, it is such an intriguing galaxy, so many swirls and the accompanying galaxies make for a lot of interest in the scene
One of the coolest bit of this galaxy though, is a faint two lobed outer loop extension. It is hard to pick up in your image as displayed but extends down to the lower right and out of the frame in a 5pm direction. It is discernible in your image under a strong stretch. If you had positioned the galaxy a bit further to the upper left and rotated the camera slightly clockwise you would have fitted it all in nicely I recon..?
Anyway, that's just an aside, still a great shot.
