I present a work done in collaboration with another italian astrophotographer, Stefano Conti. We have taken this beautiful galaxy with its neighbor in the past we. I think I can say that we went very deep. Considerable effort lavished on the management of color and detail and in putting together data from different instruments with very different fields.
If anyone is interested in taking a look at our result, the link is as follows:
