That really is an awesome galaxy grouping Fabio. Shame it is a bit low for us down here to do it justice, although I ahve imaged it many years ago with my 12"LX200 but it was very low in the sky. That galactic cirrus is everywhere really. In the past it either wasn't recorded or when it was people didn't really know what it was and often mistakened it for gradients in the image and just processed it out
Lovely result
