Thanks for this further note. Attached a crop on the galaxy, high stretch and inverted, no noise reduction nor other algorithms used to avoid to add any artifact, just a very strong nonlinear stretching..
I am not sure if what is out there is a system of shells or a kind of very faint spiral arms, definitely somebody with a much larger scope and deep exposure could get more details on that. After all I just used a 140mm lens at 1.83 "/pixels, too small to perform these studies..
Maybe it could be a good suggestion for somebody with a larger telescope next season this object gets high in the sky
Thanks again for the interesting exchange..
