Inspired by Mike Sidonio's attempts to show the extended halo of NGC 253 I have attempted to do this too. Not sure if the experiment has been entirely successful but you have to try these things. Unfortunately, my FOV is too small to include the Peter Ward S-bend
Constructive criticism appreciated...
